[Q] Changing the battery for Acer A500

Batteries performance degrade overtime so are we able to change A500 battery if it is degraded or can we even upgrade it with a higher capcity in order to achive better performance?
Is their a tutorial for such procedure?
UPDATE: I would like to thank bvdrax for his help we are one stop closer to understanding our tablets

I was thinking about that this past weekend. That's one of the few things that I would like, that it currently doesn't have (a user replaceable battery). Although, I would imagine that we could find a battery that would work with it and replace it, if we didn't mind opening it up and voiding the warranty!

Of course the battery may be soldered in, at which point even if getting the case apart without an issue is easy enough a soldering job would be needed. I would guess the warranty would be long since over by the time our batteries start going.

google openiong iconia or something like that
There is a walk thru I Sen a week or so ago on replacing battery and so on. I think this device snaps together at the seems at top and bottom. Ibhave notices the button of mine is a bit wider crack then the top. So I do think this makes sense.

By the time my A500's battery dies enough for me to care, I fully expect to have replaced the tablet itself. My Droid's 2yo battery hilds up fine still under much harder use (including hotter processor and case temps from overclocking and from living in a car mount.)

There is a post on androidtablets.net that shows the tablet partly dissembled. I can't post the link because I don't have 8 posts.

I pulled the battery out of mine just now. It is not soldered in. The case came apart very easily using a pampered chef plastic orange peeler, and just easing it into the seam and following it around.

The back of my box said 3260mAh x 2 ( 24.1 Wh ) ... is there 2 batteries ??
you mind taking pictures showing the steps of dissecting this baby ??
BTW ... that attached pic is way too small to see anything ( at least I saw the plug...that's a good thing )

Once I find the good camera I will take some better pics of how to tear it apart.
Try the link below for a better pic.
I am pretty sure this little plastic job has 2 batteries in it, as it looks to be segmented into two compartments. Also, the leads seam to indicate two batteries.

^ 2 cells, not 2 batteries. A battery is merely the word for a collection of cells.

Here is a quick video of me cracking my A500 apart. Also, I have some better pictures of the inside with and without the battery and the battery itself.

Thanks for the pic/video bvdrax
still not seeing 2x battery ... and it said Lithium Ion on the battery ...while it said Lithium Polymer on the box ..etc
Li-Ion & Li-Polymer are similar but different.
Whatever
at least it's not solder on.

Thank you in behalf of all the Acer Iconia owners who are curious to see how we can crack this one open. You are one brave individual for trying and succeeding and making it possible for us to see how easy it is to do so. More reason to love the Iconia, replaceable battery!

Let us know if you find a Mini PCI-E slot while you're digging in there.

thanks BVDRAX! Great job man!

The average Li-on battery carries a ~3 year useful life. More likely than not, three years from now most of us will have a different tab and you'll still be able to use yours over a/c.

If you look at the 3rd link (or second link in the stills) there is a spot for a standard mini pci-e card, however there is no socket installed and looks like there is a number of electronic compnents missing which are associated with it

You are a brave soul. Thanks for risking your warranty to show us how to do this!

thx bvdrax!

Wow, great video and pics. Thanks a lot, good to know whats in there and how to get there.

Battery voltage when fully charged

Hey guys,
can you post what voltage you have, when you fully charged your sgs2?
my value is 4,145V i'm just curious if thats the value i should have when fully charged, or if i should calibrate my battery (i switched some roms)
thx

I've got 4125-4135mV

ive got 4215mV hehe, healthy battery

The same at my cell.
Sent from my GT-I9100 using XDA Premium App

last time i calibrated the battery i reached 4,205 , that is my personal record. But this value is not very significative because it depens from the corrent usage of the phone. Screen on + cpu running a little bit can decrease voltade showed by 0,1 volt. And i also noticed that the charging process is strange. I assembled a little photovoltaic power station and i know the charging process of lead acid batteries. Because they are composed by 6 elements connected in series, at the end of the charging process the charger need to provide for a short time a voltage 1 volt higher than the normal to equalize the cells. The behavior of the Galaxy s2 charger is similar. The top voltage is reached for a few minues then it decrease to a float level. Very strange thing because the battery is a SINGLE cell and don't need the equalization charge like lead acid batteries.
Probably i just have to study much and play less with my galaxy

Roughly the same.

this time i have 2,204V right after reaching 100%
i guess it varies a lil' more than on my hd2 (i had always the same value there)
EDIT:
obviously i mean 4,204V haha

4,152 V most of the time. Didn't notice it go higher than that on my phone

Please tell me how often you do the power cycle and how?
Thanks in advance

i power cycle every time, charge it full overnight, use it for two days, then charge it overnight again
rinse and repeat

mine was just at 4195
i left it on charge for about 30mins after it beeped to say it was full and just callobrated it as i have been flashing loads of stuff all day

After three calibrates, I get a max of 4.200v and a min of 3.451v

My review on this product is basically this.....
This product is amazing in every way it's described. Small, portable, lightweight, lots of energy, and can charge anything.
It comes with 2 ports to charge (can be used at the same time), and 1 port to charge the actual battery.
Can charge my iPhone more than 6 times....I have not been able to test it efficiently, but it works, and it works well!
How to describe this product....
Think of an iPhone 4 in a Otterbox. Now imagine it was a bit longer like an iPhone5. Now imagine that it looks like an iPhone, yet there isn't really a screen, it's just for looks. Now what you do is you put this charger in your pocket with your phone when it's getting low (or in the car, in a bag, purse, whatever), and than you instantly have POWER IN YOUR PANTS.
I've been questioned....why do you have a wire coming out of your pants? How are you charging your phone while walking around? What type of magic is this?
On a more serious note...everyone phone dies...everyone wishes they could charge their phone while moving, and they also wish their phones would never die. This device does that and more.
It's programmed to charge iPhones and Androids faster than normal.
It comes with a ton of connectors to charge tablets, all phones, laptops, and basically anything I can think of.
for $40...it's a steal. Buy it, you'll love it. Thank me Later ♥
My review on Amazon is very basic, and lists the only two flaws I saw....
1) The iPhone connector will unattach itself from the provided cord that comes with the device. I think the same applies for Androids, and tablets. I suggest using the standard cord your device comes with to connect to the external battery.
2) there's a lot of important attachments that come in this very small bag, and all the pieces are very small. None of them are really needed besides the USB cord to charge the battery, but I wouldn't want to lose them, and yet they are so small...I likely will. Wish there was a small zipper in the protective pouch it comes in.
Conclusion:
★★★★★/★★★★★ (A universal product that should be owned by everyone)
Cost: $25-$40...I suggest buying the largest one, simply because it's an amazing deal. I bought it for $50 not too long ago, and it can be a life saver. (Think about the shows where you get lost in the woods, and your phone dies) ^_^
Edit: basically changed my review on amazon to this. Hope that's alright with you guys.

where is the link for this thing or even a name for it to buy? i am not seeing it. sorry if i missed something.

My apologies, I seem to have forgotten to place both! It's made by Anker, or can be found at iAnker.com, or this direct link to Amazon. http://www.amazon.com/gp/product/B009USAJCC/ref=cm_cr_ryp_prod_ttl_hst_61
Sorry about that!

Anker user checking in. Love mind, hooks a great charge and is portable enough to carry around.

[DIY] Mobile Charging Dockinstation

Hi there, thought i might post another little Mod that came into my mind
We all know that the Xperia-Z ist not quite an endurance runner when it comes to Battery-Life and i guess most here will most-likely have a power-bank with them, just in case.
Problem with that is, the o-rings are prone to damage due to opening the flaps all over again.
This is most-likely also a main-reason for water-damaged devices, you know it, i know it, and Sony knows that too.
So lets see what we can do to that dockingstation, so that we get a mobile Power-bank Dock.
Its actually plain simple, you simply get yourself a so called "EasyAcc 3000mah U-Bright"-Powerbank, this Powerbank fits easily centered unto the Back of the Dockingstation without being distinguishable looking at it from the front side, and if you dont know the Dockingstation even sideways.
The Dimensions:
Topside of the Sony Dock : 14,4cm x 3cm
Easyacc 3000mah U-Bright : 10,7cm x 2,2cm
A picture of the Easyacc:

}
which would basically go behind the XperiaZ, and look like this Illustration:
The way you fix it in place would be really up to you, probably glued, or by using neodym-magnets, or probably even some Velcro or zip-ties.
Other than that you just really need a really short usb/-to/microusb-cable that goes from the Power-bank to the Micro-USB-Port
Hope this probably is useful for one or another!
Thanks.

That's actually not a bad idea!

Does anyone know what the voltage/current specs of the dock that connects via the 2 connections on the left side?

Do you mean polarity or really only the specs e.g. Voltage/Amps? The dock itself has an output of 5V/1,8A which is kinda funny as the default Sony-charger is rated 5V/1,5A
The mentioned Easyacc Powerbank outputs up to 5V/2,1A without (verified) getting hot.
Hope this might help

Apparently, the top contact when holding the phone is +.
See this post that states that + is the left pin when looking at the dock from the front.

If you are holding your phone horizontal with the connectors facing down (like you would put it in the dock), well then:
LEFT-> POSITIV
RIGHT-> Is negative.
Its actually even marked on the Dockingstation itself, in case you have the Dockingstation
See:
Hope this helps

Nice!
I had something similiar for my SGS3 but was missing something alike for the Xperia-Z.
Well i now did the modification mentioned above and iam good actually
Eventually get a power-case later on, although i kinda like the Xperia-Z as it is (thin as hell )
Thank you anyways for mentioning it, probably a better alternative to other Users

3500MaH Spare BATTERY SPOTTED in the WILD!

Hi Guys,
Did anyone come across this battery? http://www.ebay.com.my/itm/Quality-...850?pt=LH_DefaultDomain_0&hash=item2ee3147afa
its a 3500mah battery.... how would you know if it is not safe to use?

i think this is a fake...
Do not shipping to germany is a indicator that they have big Problem with the german law... think, do not buy

For $10, it will attract some curious people. We will just have to wait and see the review and feedbacks. But when demand goes up, price goes up.

Then the phone will light on fire as a new and improved feature of the battery ahaha.

who's gonna be the first to try quick charging with that battery?

OK, I've said it in the past... I'll say it again...
Don't you all think that if LG could, they would have implemented a 3,500 mah battery instead of a 3000 mah battery? Especially seeing that it's a minimal cost... If it were truly 3,500 and could withstand the 300-500 recharges as its current battery can hold, then I truly think they would have done it. EVERY review simply states "it's big, but not the biggest in the new flagships" or something of the sort... LG could have had it says "bigger than any other flagship out there!"
This is a total fake. If it's real, that charge won't last more than 20-30 charges, tops, at 3,500 mah.

Actually I have seen manufacturers shy away from bigger batteries to save a few $ (even if it isn't that much). But yeah, this think is probably 2900-3050 mah. I have had multiple Chinese knock offs and the usually work but at best they match the original battery unless they are massive (like my G3 6500 Mah). Only way to know is to try it out and if it sucks get your money back and let everyone know. You'll only be out a few bucks and you might have a battery just as good as the original. My 2 cents

Battery life is fine on this phone...

I have had multiple Chinese batteries, and while they last a while for the first few charges, after that, it's all downhill. They aren't as reliable - at least not these no-name brands. I'd stick with Mugen, they make very good batteries! But hey, at least at that price you can get a battery that you can keep in your bag or something as an emergency. I didn't say it wouldn't work! I just said that the capacity of 3500 probably isn't true.
