Default Can You Bring a LiFe back to Life?

I have a 42% Fusion LHP* 6.6V 2600mAh LiFe battery in a plane that I left the switch on overnight. It is reading 3.1v. Anyway to bring this back as my LiFe chargers say battery voltage too low to even try to charge it?

I have done the same thing with 1100ma Black & Decker Lifes (senior moment trouble). I just charged them as a Nimh battery on a old charger until the voltage came up to around 5V for the 2 cell pack and then put them on my regular charger and finished the job. Did a couple of cycles to make sure they were OK, which they were. Still use them, didnt seem to hurt them a bit. They are a lot tougher than Lipos in my opinion..

Good Luck

I had one last week that did the same thing, and the NiCd setting on my charger brought it back. 1 hour at 1/2c and then finish it on LiFe setting.

I spoke too soon. It never wants to finish a charge. Used to take 40 minutes or so and after 90 it is still charging - twice. I think it is dead.

Why risk it, buy a new battery.

Bought a new battery but decided to try to bring this one back to LiFe. I cycled it about five times and it will now discharge about 2800mah and take about the same on a charge. Looks like it may be OK. What do you guys think?

I'm sure the hobby shop has another kit in stock or can order one for you.

Actually, I bought this kit from Tower and they are currently out of stock on it. So I guess I need to wait until they are back in stock before I attempt to use this battery.

I did that once with a LIFE battery, I trickle charged it with a wall wart until the voltage came up enuogh to charge it properly.
The battery never came back 100% I eventually replaced it, and now use the damaged one for bench testing.
