Hello, If i get out the battery, and I the meter the voltage between the pin 1 and the pin 5 I have 0v.
But If I plug the battery into my prophet, when I meter the voltage I have 4,60v.
This is normal?? It´s my battery ok???

QTEK 2020 POWER battery,the world record, I do it my self.can last more than a week in normal
it is 1200+2200*3=7800mah, SIX times MORE than the orginal battery, and the qtek2020 is wm5.0 frmo windows mobile 2003， I bought it three years ago
wow
please post a tutorial to make this
i have 3 battery 2300 mh
how to do this?
thanks in advance
yes it's simply
1,open the battery
2,get 3 18650 battery,such as sony g6,or sanyo and make the 3 18650 battery electrode parallel connection,
3,connect the 18650 battery and the qtek2020 battery(when you open the qtek2020 battery,you will find an battery inside) with the same electrode
4,the battery is ok now.(FASTNESS THE TWO BATTERY)
5,FIND a power charger(you can use the original one,I prefer to KODAK charger,and I made a battery base using a used tape)
6,you can charger with your phone ,but I advise you to charging the battery single with the charger.Because it's slowy using phone.
what important is:
You can't use the orginaly battery.Because the Orginaly battery is so smart that it count the charging electronic for only the orginaly power level.for example :your orginaly battery is 1200mah,and you charge with 1000ma,you will be notice that it's full after an hour,and can't be go on charge .
I destory my orginaly battery ,and I using the compatible battery later and succeed.
look at the pic careful and it's ok.
I charge the power battery using the kodak charger in 1.2A for 9 hours to make it full.
and I can do anything I wish.gps(bt),reading book,playing games...and no worry about the power supply.
why I still using the QTEK2020,that's because the largest screen and strongest cpu in ppc
Don't you have to connect the 3 AA batteries in series to get 3.6volts? (the original battery gives 3.7volts)
oh,it's 3 18650 LION BATTERY ,each of the battery is 3.6V-4.2V,,it's not 3AA battery
how i make charge my prophet battary with external charger ??? and i have one with 2 pins
I bougth a 3200mAh battery on ebay, when it arrived, I changed my old battery.
The new one lasted for 2 days afther a full charge (12h BT on, 2h WiFi, and a lot of GPRS messenger)
at 2% I wanted to recharge the battery but afther 1 minute it doesent charge anymore it drains itself and charge again to 2% an stops and it does this over and over
what can I do? any sugestions?
Maybe the problem is with the charger could not withstand it or the batery that u brought has been used before when you have not buy it or the batery is spoit when arriving.
hy, meanwhile I changed back to my old battery, plugged in the charger, it showed that it's charging but it was actualy discharging, the % where going down, could it be a phone hardware problem?
buy some charger with 2000 mah or higher..
Buy The Charger That Has A Stronger Voltage
thank you for your interest, the problem was not the charger, just the Uni charging port, Because my Uni is real used the port metallic part was loosen so I tightened it together a little bit, so now my 3200 battery is charged via USB from my laptop in aprox. 9h
but it is an idea to buy a 2A charger (the original is 1A)
I forgot the usb cable in the office and I have to charge the HD2 battery. I tried connecting the PSP charger directly to the battery blades for 30 minutes but nothing seems to have charged.
PSP Charger: 5Volt 1500A
The HD2 battery have 3 blades:
[+] [?] [-]
Did I have to use the blade in the middle as positive or negative?
Do you know anything?
Thanks
The middle one isn't needed for bare wire charging.
Just a thought but did you put + to + and - to - ? ( which you should)
Got an old mini USB cable? Use that, end off, black to - red to +,,,, and thirty minutes is about 28 minutes into the danger of explosion/damaged battery zone.

Try to measure charging current with a simple multimeter if got one and put a 1.5 kOhm resistor in series with battery and charger. This should limit charging voltage on battery poles to regular 4..4.2V as needed for Li-ION battery charging. Seems like internal battery security circuitry detects overvoltage (above 4.3V) and cuts off charging.
Hello,
i had resently installed a Nexus 7 Tilapia in my Car.
I had removed the Battery from his own Circuit Board and conntected it to a DC-DC Step Down Converter (10A) with a Output Voltage of 4.25 Volt.
After some time of Useage the percent of the Battery slowly decreases, but the Voltage stays Stable.
Does someone know how to fix that?
I want to Keep that board because of the Battery Display (100%) and the Clock.
Thanks.
Hello there .were you able to fix this issue?i am facing the same thing right now in grouper.it was drawing battery,so I connected the tablet directly to my car battery with dc dc hoping to solve the problem but instead the percentage keeps dropping and I have to disconnect the pcb board (battery board) and restart the tablet.i see 100% and then it starts dropping ?
hello, no i dont. that peace of shi* broke down, so i trashed the whole project. sry
