Re: How to identify cell phone battery terminals?"

I have a dead cell phone with no charger I want to try and recharge
from a power supply. It's a Sprint PCS model TP1100 with a LiOn battery
model LGLI-AAEM. There are 4 terminals on the outside of the battery
with no voltage reading between any terminals. There are no polarity
markings, but there is a 10K resistance reading between the center 2
terminals. There are 3 terminals on the inside of the battery that
contact the phone circuitry. The 2 outer terminals on the inside are
shorted to the 2 outer terminals on the outside of the battery pack.

Any idea how to identify the positive and negative terminals to
recharge the battery from an external power supply?

If it reads 0 volts, my first guess is that it is not be rechargeable at
all. The terminals with the 10K resistance reading are probably a
temperature sensor. There may be a fuse inside the battery pack which is
blown.

I'm not sure what kind of charger you have in mind other than the original
one. Li-Ion charging requirements are rather exacting, and batteries can
explode if mistreated.

I have no idea who this "Genome" character is.
