Hi!
I had a battery probelm (same one everyone else seemed to get with there 1yr old uni) where it cuts out at 60% due to the voltage from the battery dropping below the threshold really fast.
Anyway I got a new battery .. my old one was 1650ma (or something like that) I got this new one which is 1750ma (or something like that).. definitely different.
Now I plug my original charger (5v 1a) into the pda and the charge light turns on .. I leave it for an hour and the battery hasn't charged any.. in fact its lost charge as you'd expect if it had been left switched on with no supply.
So.. I plug my motorola krzr charger (5v 550ma) into it and go for a shower/sh*t/shave come back and the battery has gained 10%.. great! atleast I can charge it now.
I also have a desktop cradle charger (5v 1a), same problem.. it sits there forever and a day and discharges... no charge.. (I only got it when I got my new battery so could not prove it before hand)
USB charging works with no problems (not from the cradle one though). So my question is ... Why?
Could it be something to do with my new battery?? I got it from PDAAddons and they've always been good in the past so I believe I can rule out it being a fake.
My new battery is a Li-on Poly.. I've got to admit I didn't look at my old one to see if that was a poly too ... was definitely a li-on though.
I can live with using my moto charger on my exec but unfortunately the ac adapter for my cradle is of a different connector type (female pin sleeve thingy like nokia) so before I search the world for a 5v 550ma version I could do with knowing if i'm barking up the wrong tree and about to waste my money..
Any electronics whizzes in the house say ho!
anyone? :''-(
Aahaahaa!
I'm here! Now, what you say sounds very interesting and yet very strange, why?
- Normally more current from the charger should be better, you cannot put in the PDA more current than it's factory maximum (which I don't know how much it is, but that's not a problem), the internal charger (inside the PDA) knows how much it is and how to limit, also takes care of the right charging profile for your battery.
- You don't have to worry about the exact battery type you bought, boths are Lithium, so chargind profiles are mostly the same, these (LiIon and LiPoly) are "exchangeable" usually (I've heard of no problems until now, since several years I mean).
- If your battery is discharging means only one thing, you're not puttin current into the battery, you're taking it out of it! So, either you might have a deffective charger, a deffective charging circuit (the one inside the PDA) or a defective battery.
- You can charge the battery with your Moto's charger, so battery is probably ok, you have used your original charger/craddle until now, so they might be ok, you have charged one battery at least to 10% so PDA should be ok.
What can it be?
Possibilities are:
Slightly deffective PDA's internal charging circuit, the fact that you can charge with a lower rating charger (the one for your Razr, thing that I've done myself two weeks ago), might point to this, because you have already "limited" the maximum current to 550mA (Razr's charger max current).
Slightly different battery, most of the batteries do have some kind of thermal protection circuit inside (chip + temp sensor, etc.), if the behavior of this circuit is not "compatible" somethin strange can happen, however I personally consider this option not to be the best.
One or two of your chargers might also be somehow "deffective", why? Your original battery might be ok and you are just having problems with your chargers or your High capacity chargers (the original one and that from the craddle) have some problem to give enough juice to your batteries.
I surely might proceed as follows:
try to charge both batteries with a stand alone charger, this is not an easy task, because Lithium batteries are the most "delicate" types, charging method is the "strangest" one, I have two stand alone battery chargers that came as gift with some Nokia batteries I bought from an Ebay seller, eventually, I could give you the full schematic so you can construct it (if you want and if you can).
In this way I will not have any more suspects from the batteries.
Second, test each of my chargers, it can be done by connecting a medium -and suitable- load to each charger for some minutes.
A wire wound ceramic resistor should do the trick, ie for the Razr charger (5V, 550mA) I could use a 250mA load, R=V/I, so 5V/.25A equals 20 ohm (1.25W max power, use at least a 2W resistor, 3 or 5W better).
If the internal PDA circuit should be defective, take it to fix or try to fix for yourself.
Hope this helps

There is some anomaly about charging with a plug-in charger. You may have to turn the device on so that it can recognize the charger, then close it and let it turn itself off; or perhaps it's turn it off then on, I'm not sure, but I've encountered similar oddities with both 110v, 220v, and 12v chargers, and I've seen discussion about this anomaly on this and/or other fora. Once you get the AMBER light, you're fine (as long as it's putting out at least +5v; +5.5 is better).
I think it has something to do with its looking for a [non-existent] USB signal along with the voltage under some conditions, but not others, but that's just a wild guess. Anyway, I don't think there's necessarily anything wrong with your battery, device, or charger. Hope this helps. Cheers,
Thanks for the reply, I'm 100% that the amber light turns on. Not only that the screen brightens so it definitely knows its connected. I've tried several combinations of turning it off/on etc during the charge/before but nothing seems to make this desktop charger actually put anything in the battery.
New pocketPC user. Got the Tilt a couple of days ago. First post, so forgive me. Very PC literate - still learning on the pocketPCs. Testing out ROMs now, thanks to all of you.
When I bought my case (Krusell), I just added on an aftermarket car charger (Fosmon). But I've been reading some of the posts about blown USB ports and a few other issues that seem like they could be power related. As a noob, did a ton of searching on the forum and can't find where anyone has given any opinions about aftermarket chargers. Part of me says stick to HTC or even AT&T brand because they are made for the unit (although an actual HTC is a pain in the ass to find and get shipped to me in Florida for an upcoming trip). Another part says they're all probably made in two factories in China and all I'm doing is paying more than twice as much for the same unit. Just don't want to risk having a problem on my new baby.
Any opinions?
I've been quite happy with my VersaCharger Pro from Boxwave -- works as a wall or car charger, and can put out the 1000 mA the Tilt needs.

Bingo! I've used Audiovox(HTC), Motorola and Blackberry home chargers, Motorola and no-name car chargers, my work laptop and my home desktop and all have charged my Tilt with no problem at all.
I'm interested in this particular topic too !
It's actually quite hard to get the specs (current in A and voltage in V) for official car chargers ! (and quite hard for many chargers).
The official wall charger gives 1 A and 5 V.
It would seem that you don't find that many mini usb chargers providing 1A.
You can find some on ebay but then most would provide... 5.5 V... could that arm the Kaiser ? I wonder, if anyone's got an idea.
Going for a lower current would mean the charging would be much slower.
Some extra notes about USB car chargers. Usually they will only provide 500mA and you won't have them work well with a regular sync cable (usb <-> mini usb) except if you mod them by welding two pins in the mini usb part (look for more information on the hermes section of this forum).
Today I had someone tell me that the best option for a car is actually an inverter with a home charger plugged into it. They said that Li-Ion and other rechargeables aren't meant to be charged via DC and that's why they sometimes (albeit rarely) brick via car charging. However, an inverter will prevent that. Sounds like BS to me, but I am not knowledgeable at all. Thoughts on this?

I flag BS! The charging circuits for the li-ion batteries are not built into the charger itself. Its built into the device. The purpose of the plug-in chargers is to provide enough current/regulated power to run the device and charger it.
Hello all
I value the opinion of the members here so I wanted to ask an updated battery question for my FUZE. There are many threads here about different batteries, but most are old. I am looking for current info if any.
Background:
1) I do not like the way the extended batteries look and how huge they make the phone.
2) So I am looking for a second backup battery (regular size) that I can have charged and with me on business trips to use when first battery runs out of juice.
THE QUESTION -
Can anyone post current links to backup batteries they have purchased that either have cradles with them, or some other external way to charge them outside of the phone. I need to be able to use my phone while the back up battery is charging.
Thank you everyone for the links and feedback.
Also - is there something like this - http://www.daydeal.com/product.php?productid=27821&cat=3792 that comes with the cradle AND the second battery THAT PEOPLE RECOMMEND. Thanks
I am in the same boat. I am reluctant to purchase batteries off ebay for fear they are fakes. There are way too many "too good to be true" deals. I made that mistake with my Tilt and I am reluctant to go down the same path.
Daydeal.com looks like they might be legit.
That site looks ok, and the cradle looks good including the dock for a second battery. Has anyone on the forums picked one of these up?
dwight.
I picked up a extra Seido battery, but am also hoping for some type of 2nd charger or dock. This one looks rather nice, but I wonder if there are any other alternatives (such as an official HTC dock)?
If anyone does pick this up, i'd love to hear an opinion on it.
pick up the seidio 1500mah extended battery. it is really your only option. it easily adds 2-3 more hours of usability.
Pulled this off another thread. Looks better than the one on daydeal.
http://mobile.brando.com.hk/prod_detail.php?prod_id=03819&dept_id=039&cat_id=1149
I purchased this one - http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=350158863101
I received it in a little under a week. It is black, very slick looking and the replacement battery says htc innovation on it so it looks legit. it came with both a usb connection to the computer and a power cord adapter to plug into the wall. Is pretty small and compact. I will report back after using the replacement battery once it has charged for a while.
TVDinner,
Hows that battery doing for? I'm thinking of buying same deal today.
see this for emergency charge I buy them and never has a problem with runing down power finaly I can use my GPS with offroad map on mountain

I got this one off of eBay and it' great Clicky
The base is nice and sturdy, not like the cheap crap the one for my N95 was. And the spare batter lasts for along time as well, so it's all good
I picked up this dock (w/spare battery charger) for $16.83:
http://www.amazon.com/Premium-Multi-Function-Cradle-Touch/dp/B001I1LJ8M
along with this spare battery for $8.59:
http://www.dealextreme.com/details.dx/sku.16225
From my visual comparison, the battery looks almost identical to my original as far as the printing goes except the new one is white where the old one is more of a really light gray. The meter on the battery from dealextreme doesn't seem as accurate as the OEM battery but it seems to hold a charge well. I guess that's the trade off for not buying an OEM battery.
The cradle itself is really sturdy but I've noticed that if I leave my Fuze in it for too long, Activesync loses the connection and I have to unplug everything and reconnect to get it to recognize (this doesn't happen with direct USB connection). However, it will continue to charge even if Activesync loses the connection. The cradle comes with a miniUSB cable and an AC adapter (barrel plug) that can be plugged into the rear. The spare battery charger will only work when the AC adapter is plugged in but either connection allows the phone to charge (both connections at the same time is not recommended).
My battery and doc
Had the same problem, and found (with my previous Hermes) that having two regular batteries and a doc that could charge the phone and extra battery at the same time was the best solution. I went to the AT&T store and bought the extra battery for $35 or so. At mobileplanet.com (eXpansys) I bought the extra battery charger/dock http://www.expansys-usa.com/p.aspx?i=172873 that has been great since. One word of caution (if you care)- the dock/charger comes with a wall charger cord that DOES NOT end in a mini USB. Therefore the dock uses the standard round 5V connection instead. Since mine stays stationary next to the bed (i grab the batt and phone each day when I leave, and put them back at night) this was a non issue. However, unlike the HTC branded one for the Hermes, the battery is flush in the charger, rather than standing up at an angle behind the phone, so this dock is a bit larger 2.5" by 4" then previous versions, but does all you are asking for.
USB Charger w/Backup Battery Support
I found the same charger on Amazon.com for a few dollars less if some of you are worried about DayDeal. Here's the link:
http://www.amazon.com/Hotsync-Deskt...GGPS/ref=sr_1_3?ie=UTF8&qid=1241719899&sr=8-3
I bought this today and am heading across the country on a trip. I'll report back on how well it works.
Has anyone tried this spare battery charger?
http://www.seidioonline.com/product-p/bd3-bcsi3htchx1-bk.htm
I don't really need a cradle. If I needed to, I could connect a USB cable to this and charge me phone as well as the spare battery.
Not really sure if its worth the price or not.
Charging Station/Dock and Spare Battery
So I received the spare battery and charging station that I ordered from Amazon. It isn't anything spectacular, but feels solid and works like a champ. It came with a 120v A/C Wall adapter and an extra USB cable so I could either use it to connect my Fuze directly to the computer by USB, or just plug it in to an outlet for charging. Works great. I would recommend it, but I haven't had much experience yet, just charged the spare and swapped the batteries out of the device.
Whos got Extended battery on there Att Fuze ?
Is it worth the bulk
& which one to get ?
1,500 / 1,800 / 2,000 diff kinds i see
with diff company
First off i'd like to say hello to everyone, this is my first post on the site.
I read the post about the 3600mah battery and it looks like the phone would sit on a slant. Looking at this 3500mah battery by seidio it looks like the phone may sit level. check it out and let me know what you guys think of this battery
I have the 3500 battery and it sits flat.

The poster that commented on the slant must have seen the same pictures I posted about on another forum. Fortunately, I was corrected by someone who had bought the Mugen 3600.
Across the forums, those who've tried both pretty much all prefer the power & size of the Seidio & the look of the Seidio cover. Plus it's cheaper.
I got my Seidio 3500 Thursday night. The instructions say to do an 8 hour initial charge before putting the battery in the phone & that performance would increase after 5-6 full charges. I did the initial charge Thursday night, put the battery in the phone about 7:30 Friday morning, was down to 32% about 4pm Saturday. I put the battery on the charger Saturday night, put it back in the phone 6am Sunday morning, am at 38% as I write -- slight improvement. It looks like a fully conditioned Seidio 3500 ought to easily go two full days...maybe longer.
I'm using the unlocked UMTS version on AT&T.
I have this battery, bought it on day one because I use a lot of data with my phone and normally, even in Edge, a 8 hour battery is CRITICAL. I can't say what the original battery can do, but this battery is AWESOME!!!! I'm getting greater than 5 days of battery on this huge guy! Even when I'm in range of the 3G/HSDPA area, I'm getting at least 2 days.
I use GoodLink with my corporate email and it keeps the data connection HOT 24x7. Usually drains a battery VERY quickly.
Another pro is that the Seidio cover is non-skid black rubber coated plastic. While not matching the "pretty" glossy finish, I like it better because the phone doesn't slide around on surfaces.
I have one issue and I'm not sure if anyone else has this battery and have experienced this issue. But I can't charge this phone/battery with any USB cable I've tried through my USB ports. I've tried 3 different cables, including the included Palm cable, powered hubs and monitors with powered hubs.
I can't figure out what's going on here... Any help here???

I can leave mine in the phone & charge it using my Palm cable or the retractable Seidio cable. I also have a Mobi Products cradle -- phone with normal sized battery in the front slot, the Seidio 3500 in the spare battery slot, both fully charged when I get up in the morning. Sounds like you might have an issue either with the phone itself or your USB ports. Are the ports fully powered USB 2.0 compatible?

You must have the windows mobile device center/activesync installed on your pc in order for the device to receive power.

In the Treo Pro manual you will read that the phone takes much longer to charge on a USB connection. In other words it is suggested to use the AC adapter and the usb cable to get a powerful and fast charge. That being said maybe the battery needs and AC charge and USB wont suffice.
I have read so many reviews and your problem is a one of a kinder.
About getting this battery cheaper.
Go seidioonline.com and enter coupon code: ITB0630 for 10% off an order over $50.
They sell battery $65 ($5 cheaper than most) plus you get 10% off.
My total purchase was $64.35 shipped.

I don't have a Treo (yet) but I've had the same on other devices.
The thing about a USB cable is that if no driver exists to tell the device what it's connected to, it doesn't know whether it's USB2 or USB1, so can't assume there's much power to use. (though I would have thought USB1 still presents a useful amount).
Some devices charge slowly on plain USB without software, some don't charge at all. Of those that do trickle charge, the rate can be less than the power consumed by keeping the backlight on and/or running the GPS, so all that happens is the device stays awake and runs flat quicker.
Sometimes there's a pin in the connector to indicate "this is a charger that supplies what's needed", and you can get an adaptor cable to use with generic USB cables or chargers.
Was thinking of ordering one on eBay found HERE.
Would be around €40 + €17 = €57. But this would mean it has to be shipped from the States to the Netherlands. Why isn't their any battery available a bit closer to home
At this time I get just two days if I'm lucky. Doesn't seem that to many use the 3500 mah from Seidio though. No more users tried this baby?
Bought one of these guys to hardwire a charger in my car:
http://www.mountguys.com/product_p/mfx5v-b-micro.htm
On the charger is specifies 5V 1500mA output. Is that ok? I know it's more than stock, but I thought circuitry can step it down if needed.
Also, I'm thinking I want to hardwire to the always hot lead that goes to the radio memory function. Any chance of current problems? Don't think it will drain my battery if I leave it charging while shopping (or at the bar)
Thanks.
I'm curious why you chose to hardwire it, when the device can only pull 700mA, and these little wonders work perfectly.
Nice! Got one of these also... twice the ports and 5X the price:
http://www.amazon.com/Griffin-Powerjolt-Dual-Universal-Micro/dp/B0042B9U8Q/ref=pd_cp_e_2
Yours and mine above specify 1A... this one:
http://www.amazon.com/Charger-Samsu...96/ref=sr_1_15?ie=UTF8&qid=1318442293&sr=8-15
2.1 A.
I just wanted a cleaner look in a little sports car... the hardwire is going to come out the panel and go straight to a dock. But now I'm worried that 1500 mA could be troublesome?
It won't be troublesome, just useless.
I have a setup for my iPod that utilizes one of what I linked. I've got a USB+RCA-to-dock cable running into my center console, then into a port in there, to some empty space in front of it (under the trim, totally invisible) where my audio guys spliced a new line into the RCA jacks that came from the factory, and split off another power line. The charger's in there, cable connects to the ports... It's nice and clean.
this should be fine. the amperage rating on a charger just tells what it is capable of if requested. it is up to the phone itself to provide the requested amount of current. that is to say if this charger can provide 1500mA, but our phones can only use 750mA, your good. it is provided all the current it needs. now on the other hand, if you were charging some device that could use 2000mA(unheard of) this charger would provide all it could, the device would just charge slower.
the voltage is fine. most chargers are rated at 5v, and should be spot on as long as it is a decent brand from a trusted source. a knock off may be out of spec to what it is rated. that is where you could run in to trouble with frying a phone.
anyway, besides all that, this seems risky. not hardwiring a charger to your car, but leaving it there while you are shopping or in the bar. ever heard that an ounce of prevention is worth a pound of cure? id hate to come out of a bar to a broken window and no phone...
i never leave my phone unattended outside of my home.
