8125 Battery Alternative

I recently left my Cingular 8125 in Bootloader mode over night, connected to my PC not knowing that it couldn't charge while in that mode. I woke up, and couldn't turn it on; I eventually found out that the battery couldn't charge while in Bootloader mode.
The only solutions that I've seen posted are to: (A) Get another charged battery, (B) Charge your battery in a working Wizard
Both solutions aren't possible for me at the moment... what I needed to know is if there is a way to charge using some funky wiring rig using standard AA batteries to power it for about 7-10min. or so.

Cut one end off an old usb cable. Then plug the usb cable into your computers usb port and touch the black wire to the (-) on the batt and the red wire to the (+) on the battery. It takes a few minutes, but the battery will charge. Then put the battery back in the phone and boot into the os. Then charge the phone as usual.

You can jump some wires to your battery from a battery charger to get some power to your battery --- need 5.7 volts -- positive to positve, negative to negative but I would not recommend doing this. Your battery is a lithium Ion which takes a special charge. Take it to a Cingular Store and ask the clerk if they could just charge it up in another phone for a couple of hours. I'm sure they won't mind.
Lithium Ion batteries are fussy about how they are charged, so its best to do it in another phone or a charger made for your battery.
Cheers!

Thank you guys sooooooooooo much for the info.
You have no idea how important this is.
EDIT: I stripped the USB cable, the outer wire is silver and there is quite a bit of it... there are four wires encased in the middle: one black, one brown, one red, one orange... I do not know which wires to connect to the pads on the battery.

fix: for battery completely dead.

Here you go
tools.
-2 usb cables
-wire cutter or box cutter
-computer- laptop
-wallcharger (optional)
btw dont try cutting up the wallcharger(you may electrocute yourself) only USB CABLE!
easier fix, take a standard usb cable. rip off the smaller end with a wire cutter, expose the red and black wire. take out your battery, than connect the negative(black) wire to the negative end of the battery, than the red wire to the positive end of the battery, leave it in there for exactly 3-5 minutes for jump start. after that turn your wizard on, and quickly shove it inside a new usb cable. or the wall charger.
note:
if not done correctly, you may damage your wizard or the battery. if theres a power overload or your power goes out. your wizard will burn out!
feedback is greatly appreciated.
p.s after that my battery seem to be weak, charge barely holds for 12 hours. after 12-14 hours it will die out. so i suggest buying a new battery after couple of days.

how to charge htc 8125 with no original usb cable and(or) without orig. wall charger

hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks

charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!

no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway

I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.

I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.

seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.

Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.

thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging
//pinouts.ru/CellularPhones-A-N/razrv3_charger_pinout.shtml
so, any more help will be appreciated a lot
thanks

SOLVED: HTC Wizard (Cingular 8125) Dead Battery Wont Charge

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!

Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.

hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?

So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.

old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.

Dead charging circuit?

Hi everyone;
I've having an interesting time with my nexus 7 (2012 wifi 32gb).
Before I left on vacation I couldn't get the thing to charge. Looking at the usb port I thought it had become to damaged to make a good connection. So while I was away I ordered a new port assembly. Installed that and still no charging.
Oh the battery cell voltage had gone down to 2.2V so it's in a sleep mode. No problem used a proper lion charger to trickle charge it back to life then further to about 3.8V.
At that point it boots up though the optimization took the charge down to 2% so couldn't do more testing but clearly it worked just fine. However the thing won't charge. Plugging it in to USB it does detect the connection but does not draw any current (as shown by a usb voltage/current monitor). It will show the charge screen, go through 3 cycles of the battery filling animation then shut off.
I check and the voltage is getting from the usb cable into the connector. I traced the ribbon cable from the IO board up to the motherboard and at the other end I also get a nice 5V reading. Clearly the connection from the USB to the device is being made no problem.
At this point I am thinking that maybe I blew the charging circuit. When I was orignally trying to get it to charge before leaving I was applying all kinds of stress to the connector to get it to charge and there was a few times where I think I shorted it (usb monitor showed >3A and the device reset).
Anybody have another theory?
At this point I can't really use it as charging the cell externally is dangerous and not convenient. At this point from what I have seen with my testing and on here if I want to use it I would have to apply 5V to the battery connector (sans battery) which I haven't tried yet.

Weird charging issue...

Hand my Nexus 6P three days now. Everything has been fine until this after noon.
Came home and put it on it's stock charger took it off a few hours later and noticed it was at 78%. I put it back on the charger and say it was not taking a charge. Here is where it get strange. The phone will charge off other chargers and the Nexus Charger will charge my LG G5 but the Nexus xharger and the Nexus will not work together.
Don't know if this matters, but I have noticed that the USB-C port of the Nexus 6P is a bit tighter than that of the G5.Don't think that should effect anything, but thought I'd mention it.
As i just got it I'm considering taking it back to Best Buy, but it's the 128gb model and I'd have to wait for a replacement.
Any ideas or should I just exchange it.

OK, this is a new one...
I rebooted the device and it seem to be charging with the stock charger again.
I'll have to keep my eye on this.

In the past I've noticed charging issues (on the 6p or previous android devices) can be caused by a dirty usb port (sometimes it's even caused my phone to restart over and over). I *carefully* used a bent paperclip and a *small* piece of cotton soaked in rubbing alcohol (I used ripped the end of a toothpick) to clean out the port. I got a decent amount of gunk out of it. (Caution though, I've also broken several ports and had to send for an asurion replacements when I wasn't extremely careful while pressing down on the middle tab/contacts of the usb port.)

Hummm.... I might just use compressed air every so often to try and keep things out of the USB port. Don't wanna be sticking things in there that might break it.
But the phone is just a few days old so I don't thin that was my issue.

I have a new Nexus 6P, and mine seems very finicky when charging over USB using a Benson Leong approved Type C-to-A connector. In fact, I end up losing a charge quite rapidly sometimes, as if my Nexus is trying to charge my desktop computer (i.e. "power supply" mode), even though it's in USB charge mode. However, it will work fine on a wall charger. I try to avoid wall chargers since it's hard to beat computer power - I mean the wall charger isn't a 650W 80+ Platinum PSU with all the fancy safeties and ripple suppression. Any idea what it could be? I think it might be a software bug.

First, just use the wall charger.
"I try to avoid wall chargers since it's hard to beat computer power - I mean the wall charger isn't a 650W 80+ Platinum PSU"
you are very wrong with that statement!
Depending on the trype of USB you computer has it will only supply a fraction of the power your charger will. USB 2.0 will max out at 500mA (.5A) USB 3.0 will max out at about 900mA. Many of the ports on you PC will supply even less power, usually one one port will actually supply the the full power of the USB standard. The PSU on you computer has nothing to do with it.
It is generally recognized that that using a computer to charge you phone is very slow and only if you have no other option, and even then you have to plug it into the main port to make sure it has enough power to charge (slowly) you device. Unless you lucky enough to have a new computer with USB 3.1 type-C that can deliver up to 3A, stay away from charging from you computer.
I just tested on four on my computers USB ports on my computer and only one gave me a little over 1A and that almost 1/3 of what the Nexus wall charger can do.

My 6p did this after I used a cheap usb a-c cable off eBay to charge my device in the car, after a reboot and a replacement a-c cable (belkin this time) I've never had issues again. Like you I only had issue with the original nexus charger when I went to use it at night, other chargers were fine, and a reboot did solve the issue.

You're very wrong in your interpenetration of my statement. The low amperage is precisely what I want. If I'm in a hurry, I'll use the rapid wall charger, otherwise I charge my phone overnight; it's habbit and convieniet for me since I have a small room and sleep next to my computer. The slower charge puts less wear on battery and it doesn't trickle as long either. There is also a redundancy of protections - the surge and overvoltage protection of the motherboard, from the PSU itself (including ripple/noise suppression) and then there is the surge protector the computer itself is plugged into - there isn't any safer or cleaner power in the house for charging my phone.
