New battery 5000mAh - Acer Iconia A500

Anyone had heard about this new battery if yes any feedback?

Thanks

What is the capacity of the stock battery? I am impressed by how long the stock one lasts, but would much rather have a super capacity battery in there for an even longer run time.

IIRC, the stock battery is 3260mAh.

Correct, and there are actually 2 of them.
So does this mean we can have a pair of 5000mAh batteries? That would be awesome!

Actually there is only one, but this one is 2cell battery. Li-Po batteries come in cells, one cell is 3,7V. So you can build them like legos. You can add cells in series to increase voltage (1S 3,7V, 2S 7,4V, 3S 11,1V) or in parallel to increase endurance (1S 3,7V 2500mAh + in parallel 1S 3,7V 2500mAh = 1S2P 3,7V 5000mAh).

Is there a teardown guide for our tablet?

Yes, several of them.

So would this battery have a longer life than the stock battery?

Theres two 3260 bats. In teardowns it looks as though its one because both are together.

Nop. Only one, but inside this one are two cells. So only one battery.

Theres two 3260s. Not one. If there is only one 3260 I doubt our tabs would last as long as it already does. Call it one or two batteries whatever, like the specs say, 3260x2

Look. There is only one battery 7,4V 3260mAh 24WH Li-Po in our Iconia. Inside this battery are two Li-Po cells each 3,7V 3260mAh connected in series so capacity remain the same only voltage is doubled. My laptop has 9 cell battery but I'm not saying that I have 9 batteries. You can google by yourself for battery code 934TA001F you'll see only one baterry.

Ok. Sorry. Geegz. I still love you.

It's annoying, isn't it? So many people today just don't know the difference between a cell and a battery. Makes you wonder what they hell they teach in science class these days...
For those who get confused... A battery is ONLY a battery when there are multiple cells inside, linked either in series for parallel. If there's just one cell, then it's NOT a battery, it's a cell.

has anyone tried buying this yet and see if it works

They didn't teach about batteries in my science classes in highschool, nor in college. That was all in an electronics class I took for my ANSI certification.
Good luck buying one, minimum order is 100. I wonder what price per unit is, I'll email them and check details. I've made orders through them before, it's not too bad.

Secondary battery

Has anyone tried buying a non official battery for their MS2 and care to comment or recommend any? Im going on holiday to france and i know my phone wont last a whole day without charging, so I was thinking of buying a second battery.
I read in another forum that using a non-Motorola battery displays some kind of warning. I'd go with an original battery.

using a non-original battery could have detrimental effects on your phone. there was a discussion on this on the forum of another phone. using a non-original battery could lead to leaks and other problems which would eventually lead to the warranty of your phone being voided.
stick with original motorola products. yes the battery might be very underpowered, but its the safest bet to ensure the longevity of ur phone
With a non original battery, the battery indicator of your phone shows a interrogation symbol. Also, it does not charge with the phone charger.
Sorry my analphabet english xD
@Motorola Milestone 2
bp7x 2300mAh battery
I 'm using a non-original battery . The MOMAX and everything's good ,it feels just like the original one except for battery tempperature sensor. the temp is always 26 in celsius
I personally have used seidio for my milestone and it works like a charm, its the extended 2800mah one it really performs like it should and not like how a lot of people claim thats its way less than stock! It does not always read it correctly but a quick reboot fixes that, like 50% after reboot would usually be about 70-80%. They way i used to use my phone (light to moderate level) would last about 2-3 days but after the extended I got twice that and some more. Just make sure you get stuff from the original manufactures either way and don't go for deals at amazon or whatnot as those guys might be selling either defected or not proprely stored stuff. Batteries are critical components don't go cheap on them! And no, my phone has not been messed up or had any leaks or anything and I have this for about 3-4 months now. The original battery degraded in about 6months if you have to compare.
That sounds promising, does the battery need to be charged with an external charger? And does the milestone complain that you are not using the official bettery

reebooting your phone to get the exact picture also works on the standard battery. my question is, does the back part which houses the battery heat up when used? does the phone get hot during charging? do you need a new battery cover for it? and besides the longer usability, have you noticed any other performance issues on the phone?

Actually the rebooting to get the exact picture is not the same here, a jump to 20-30% on a stock battery? I don't think so. No I never encountered any odd behavior with the other battery. No getting extra hot during charge or use, get the typical little bit of heat while using 3G and browsing like mad but that would happen on the stock battery too. Battery cover for a 2800? of course, that stuff is huge! its protrudes like mad! a quick heads up though, the extended battery for the milestone 1 and 2 can use the same extended batteries. Don't know about the droid x though. Anyways, no performance issues, no heat while charging. The back covers supplied by these after market guys are not the best quality though so if you are someone who loves dropping phones and what not would recommed getting a spare back cover from the guys you get the batts from.

No, I use my original charger and no complains or warnings by the phone. Not on the milestone 1 at least. In fact some times i use my ipod's adapter so no big issue. And it charges at the same pace as the stock, additional 1 hour or whatever. restart the phone to getting a proper reading as it shows 100% but upon restart its 70-80% since only the stock level is charged. I hear this app called battery left does great for calibration.
ALSO a thing to note, I only know of Seidio and Mugen to be relialbe after market battery guys hence their hefty pricing at times. The others claiming to have bigger batteries have cheated people with stickers and what not and usually end up underperforming and degrading considerably faster than burning paper! I remember 1USD batteries for nokias back in the day good for a quick one time run i suppose but these 1USD guys are now selling them with a better branding for like 20-40 USD.
Anyways Sedio and Mugen have facebook profiles and keep people posted on the latest on devices usually there, although its kind of sad since seidio have not followed through promised products at times.

thanks for the info mate. ill do a lil more research and probably check it out myself.
Thanks for the info i have bought a Seidio Innocell Extended Life for Motorola milestone 2 from mobilefun £30.49 its the 1500mah version same size as original battery so no extra cover is required.

Cool but as I suggested try and get them off the manufactures themselves as I have noticed some people complaining when purchased via 3rd party retailers.
Also another bud of mine had picked up one for the Nexus one, that phones back cover is a full one unlike the moto's and he too can vouch for the products positive performance. Either ways also check out some reviews from amazon.com for peace of mind.

After my first day of use I got around 11 hours of use before reaching 5%. Here are the usage statistics at 15%
https://picasaweb.google.com/105351366297036719015/DropBox?authkey=Gv1sRgCJna6ZH6hLKxzQE
Wifi was on most of the time, I was using my phone for the usual things. Occasionally checking socialfeeds, engadget, xda every hour or so and internet browsing I played 10 minutes of angry bids. Updated some apps and downloaded a few new ones.
Overall not a significant increase in battery life maybe an hour or so more from what I am used to.

Time to replace my stock evo battery ?

Its been a year since i got this phone and the poor battery has had nothing but heavy usage the the entire time. Im wondering how after 500+ charges a evi battery should be holding up and what the life span of it is till its time to replace after heavy usage and on quite a few ocvasions more than one full charge per day.. Old age is a ***** haha. Thanks guys
Unless you notice it's not holding a charge like it used to, heating up a lot, or swelling up, I'd say it's still perfectly fine.
First 75% or so just drops fast. 75% through 25% so so and the last 25% holds strong like the whole 100% used to. I wasnt sure if it because miks rom and heavier usage from 3.0 though?

U got the point there. U made up my mind. I hear u cant get one thats 2000mah that fits under the stock hood? I havent found one online, any suggestions?
Yea I wouldn't mind finding that battery too. I really don't want to make my phone thicker with the big extended battery.
We're comin from a pure power source.
Usually batteries typically should last a year (or longer) but when I used to work at tmo I found that they start to lose full charge at around 8 months; im only speaking for HTC batteries based on my exp w/ their devices. If you can get another one id say go for it.

[HARD MOD]Dock + 750GB HDD + Double Battery

Edited 01/04/2012
If you're about to ask me if I've considered an ssd instead, know this. I may be an idiot, but I'm not that stupid. My IQ may be around 30 or so, but It's just high enough for me to figure out that an ssd is a much better option than an hdd. Jesus christ, stop asking this question already. The reason I've opted to put in an hdd instead of an ssd is because of cost. It cost me about $50 to for a 750GB hdd. An ssd with the same capacity will cost an arm and a leg. Go ahead and look that up.
So, please, if you're going to suggest I use an ssd, consider reading the above paragraph. And if you're going to email me telling me what an idiot I am for using an hdd instead of an ssd (like that turd a couple days ago), then also consider pushing the donate button right below my name so I have enough money to buy an ssd with comparative capacity. Goodness...
People, just because this is the internet doesn't mean everyone else beside you have an IQ of a potato. Get over yourself already.
****************************************************************************************************************************
I'm making a new thread because this is an entirely different mod than the other one.
So, I've added 2 more battery cells parallel to the other ones, doubling the capacity while maintaining the voltage. in addition, I've also added a 750 GB HDD.
Unlike the other mod, which suffered no deformation, there is a little bit of deformation in this mod. I can still close the netbook form. And if you look, you can see the curvature of the keyboard dock. It's not very noticeable, but if you know it's there you can definitely see it. Here are the pictures. I am currently testing out the battery capacity to see if it's really doubled like it's suppose to. We'll see, I guess.
By the way, while I am very happy with my result, despite the slight deformity to my dock, I definitely recommend against this for anyone else.
Speaking of which, how do I recalibrate the battery indicator? Looks like it's dropping at exactly the same speed as before.

It only affects the tablet battery. I can't get a definite answer from all my searches how to recalibrate the dock battery.
Aw, the deformation is a no in my book, but I think the mods themselves are awesome. If I tried this, I think I'd go for more batteries because I can't find enough stuff to fill my 32g usd cards anyway.. (or a secret compartment storing unmentionables).

I don't blame you. The deformation is hardly noticeable, but it is there. I'm actually happy with this setup. The slight deformation doesn't bother me. As long as I can still close the netbook form.

Well, I gotta figure out a way to recalibrate the dock battery first. It's dropping at exactly the same rate as when I only had 2 cells. Can't freakin' figure out how to do this.
By the way, I think I saw that you said your method is more refined and less risky now in another thread; is the method different, or have you refined your skills? If the method is different, could you post a tutorial? I think I might attempt it after I find out if I got into any good grad programs.. (because then I will know whether or not I will have some amount of money to burn for no damn reason ).

Both, actually. Before, I was both stumbling around blind and doing things in not so efficient and safe way. My soldering skills have improved greatly and I have also refined my procedure to involve no risk at all. It's all in the wrist, man.

Uh... no. This mod voids your warranty. I will take my methods with me to the grave.
PS - Isn't it obvious from the photos?
Added by edit.
Ok, my conscience got the better of me. There is something I left out of the photos. A key ingredient to making this whole mod work. Without this very simple but critical thing that is covered up by other components in the dock, the mod might as well be a piece of brick. It took thousands of hours and millions of dollars of research to figure out this one small piece of modification to make the whole thing work. My dock was sitting there for almost a month dead before I brought it back to life with this thing I'm speaking of.
In other words, don't try this. Trust me, you'll regret it not knowing what this thing I'm talking about is. It took me a whole month to figure out this thing. Thinking back, my goodness, the solution was so simple. And yet it took me a whole month to solve it.
Added by edit again.
I just figured out how to make the deformation go away. Damn, why didn't I think of this before. I'm too lazy now to open it up and apply the fix.
Are you not worried about charging two separate battery cells without a load balancing charger? At least from the RC world, this is a big negative. Fire can be no fun.

Exactly right, lion/lipo batteries need to be balanced in charge otherwise you will burn out the batteries and in extreme cases, BURN the batteries.
Having said that, many/most of the lipo batteries I have worked with in electronics have balancing circuits per "cell" so in reality you can simply add them like any battery and they take care of themselves. If lipo batteries were purchased without that circuit, then they are very cheap to buy and add as well.
I havent cracked the transformer, and dont plan to because the stock battery life is plenty for me; however, I have increased the battery capacity on several laptops, and other types of devices, and the first key is to ensure the cells are balanced before connecting them together, then ensuring you have a balancing circuit to EACH cell otherwise over time they will come out of balance (normal use and internal resistance). Once you have done those two things, you can connect them and use them.
Now, the other point is the meters. I have no idea about the transformer but most battery meters work simply on the voltage on the batteries and assume the discharge in a linear fashion. This is rarely true for batteries, but it is simple, cheap and gives you an idea about how much power you have left. Sometimes this is error is covered by software that "maps" the battery discharge rate and gives you a "real" battery left level. So to the point of all that paragraph, once you balance the batteries, connect them and run through a few full charge/discharge cycles, you will likely find that the meter will catch up.
A point of caution, the word "cell" does not refer to a nicely packaged lipo battery with two wires. A cell is a single constructed unit that is usually 3.7v in the lipo world (different chemistries of batteries will have different voltages). If you added a pair of 3.7v (1s1p) batteries in parellel with a pair of 7v batteries (2s1p) you could really confuse the battery meters.
Enjoy the mod, I love reading about them..

I just redid the mod. Unfortunately, it was 3am and I forgot to take pictures before I closed up the dock. But basically what I did was charged both batteries up to 100% and connected them in parallel as is with their balancing circuits. Before, I took the cells out and added them to the circuit of the other one. This time I kept the circuits and added the circuits together.
It seems to work. The new battery pack is recognized. We'll see what happens later.
Here is a picture to give you an idea.

Bottom line: don't buy it.
thanks dude.... sorry for not searching the threrads before new post...

I've got one and it seems to work better than the original battery. Haven't had any problems. Haven't been analysing though.

my friend bought one of these batteries for your defy and lasts only 3 hours
The only brand of extended battery really works is Andida , I had one in my old N78 lasted 1-2 hours more than the original
don't buy it
My cousin got this battery , apart from the inflated capacity , it battery also leaked fluid and became inflated :crying:
same size as bf5x/hf5x, significantly higher capacity, definitely a scam, may even be dangerous.
battery chemistry hasn't evolved that much in the past few years. there's a limit on the weight&volume/capacity ratio.
avoid it.
not that good
i bought it and it's 10% her half a hour :/
Third-party batteries often lack good protective circuits. They may die unexpectedly and/or kill your phone. Be wary!
There is also a possibility that those batteries don't get fully recognized by the defy and the batteries might not charge up to 100%
thanks for the warnings.
any idea where one could get a legit replacement battery?

But a battery with 1700+ does not exist right?
anyone try this ebay.com/itm/221285995275?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 battery..

What is my real battery capacity? Acubattery varies wildly

So quick question:
If I charge my phone slowly, accubattery reports my battery as being ~2700mAh whereas if I do quickcharge, I get an abysmal ~2000mAh. I mean I already bought a new battery, but how much of my original is left?
Any good way to tell exactly how much my phone will hold?

On my case, I installed a new battery then I did a test myself.
By using USB battery capacity test tool, the result is near 3100 mah.
By accuracy battery, the result is 3400 mah.
The result on accuracy battery not change for a month whatever on normal charge or quick charge. So I think the app is pretty accurate minus 300 mah.
So you may keep charging on both methods. Then use the average number to minus 300mah.
(I guess you have 4 hours SOT, right?)
I believe he's referring to actual, physical battery life. How long will it last before it starts to fail and needs replacing.
Maybe.

So I have about 1900mAh left in my battery? Lol wonderful
Guess I should get my lazy ass to tearing apart this phone and putting a new battery in. I have maybe 3 hours SOT.
According to Accubattery I now have 2254mAh battery capacity

I bought it from taobao (china online market), I dont think it support other country but china.
The seller said the battery will label random from 3100 to 4000 mah.
But I think it is fake, by using usb tester, the capacity is still about 3150 though, I dont know how the battery can fool the accubattery app.
So any battery will work just the same.

Well, I also had about 2300 mAh three or four months ago. Now I found out that snapping an HDR+ pic with less than 40% battery will shut off my device (voltage goes below the shutdown threshold from abt. 3.7V) since all cores go at full tilt when processing...
I think Accubattery's reading is good mainly for knowing when to change the battery, i.e. if it says less than 2700 it's time to get a new one. Sadly I can't find one, so I'll have to put up with this until I find someone that sends stuff to my country

eBay doesn't ship to your country?
I have about 2300mah left and if my phone is cold it will get to 30 percent then die and not reboot until it's connected to the charger.
Now I have read that someone else's shuts down I will now eBay a battery and set about replacing. Cheers

Ebay and Aliexpress ship to my country, but I'd have to go to customs to get the battery, fill in a lot of paperwork and pay double the price in taxes... i'm not sure if it's worth the hassle. I'll try to get one if someone travels out of the country

You should buy a new one, but the fix for that is maybe just a calibration

I mean, my battery was only $13 on eBay. To each their own, though.

I'd end up paying north of $40 plus having to go get it to customs

What battery did you buy? I'm looking in Aliexpress (Stuff gets to my country from there albeit after a month or two) and there are original batteries, and Losoncoer and HSABAT 3650 mAh batteries

I finally bit the bullet and bought an original one via Aliexpress. It cost $6 plus about $5 in shipping. Now to wait a month or more, as usual with aliexpress
My battery is one year 8 months old. Whenever it got down to 30-37% it would automatically shut off, no warning or anything. When I plugged it in it read 30-37% and would start right up. The battery life in general was terrible.
So I would say if your battery is over a year and a half old and your having problems with it you should think about replacing it. No software will overcome a worn out battery.
I bought my battery from ebay and put it in myself. Not as easy as some would make it look but it's doable. What helps get the back of the phone off is a small flathead screwdriver with a very thin tip to get inbetween halves and then twist to seperate.
