How to Recharge a Lithium Battery

I bought a lithium battery and completely drained it. Whoops. Anyway, can I bring it back to life?

John Talley: Yes, but be really careful doing this. With lithium batteries, you don’t just throw them on a regular buzz charger, like in the good old days and bring them back up like you would a lead acid battery. The lithium batteries have to be brought up in a certain fashion, and then topped off as far as their charge. And when one has been knocked all the way down like that, even some of the best smart chargers can’t pull it off. So be prepared for the fact that this one might not come back. But make sure you can get ahold of the best lithium battery charger that you can, to hopefully bring it back to life. Just be careful about that.

John does a rundown of how the different battery types work and why they’re used for certain applications. He also covers what chargers to use for bringing each battery type back to life.
