AA Battery Powered Cell Phone

Has the battery in your cell phone died forever? Try this to extend your phone's life time.

See picture...

You'll also need a cell phone that takes a battery of 3-3.7 volts.

If your battery case has wires on it already, skip this step.

Use the needle nosed pliers to hold the wires while you strip a small amount of the jacket off of the wire. Then solder the wire onto each of the contacts on the case.

Find what terminals on the phone are positive and what ones are negitive. the phone may not say it, but the battery is legally required to state the polarity.

Use the jumper cables to hook up the phone to the batteries and test to make sure your phone works.

Solder the wires from the aa holder onto the contacts, then cut a hole in the battery cover for the wire to come out of the case, then hot glue the battery holder to back to the cover.

BE SURE TO GET THE POLARITY RIGHT, you may want to put some hot glue over the contacts to prevent shorting.

(note, if the phone works, but the batteries are hot, you need to add another set in parallel, i had to)

After doing several tests and calculations, I have concluded that 2700mAh Ni-Cd rechargeables give roughly four times the battery life than the 880mAh standard battery.
