Rechargeable Lithium Battery Link
Since most rechargeable lithium batteries are 3.7 volts or multiples series thereof I found this article to be useful https://learn.adafruit.com/li-ion-and-lipoly-batteries/voltages

Acutally you didn't go far enough down the page of my link..
18V LITHIUM TWO PACK FOR $92
So that is $46 each and you don't take the risk of burning up you or your property.
Okay, I see it now. But these are the P102 batteries. I can get two of them for $99 CDN at the store (with a drill and driver free in the package)!
If the Ridgid truly has a lifetime warranty on batteries, I should spend a little more and get it instead of throwing money away on Ryobi. I had a good chat with a manager at Home Depot and he told me straight out that I have a two year warranty on the Ryobi, redeemable at the nearest Home Depot repair center, which is 500 km away in Edmonton. Postage is expensive in Canada and he calculated that mailing there and back would cost more than buying a new one. He agreed that the warranty is useless to everyone in our area. I expect the same catch22 applies to Ridgid products. I must explain all this to the nice lady at Ridgid's call center. Maybe she will give me a freebee.
gdetrailer, those cautions for Lithium batteries are beyond reasonable! Do you remove the battery from your cell phone when it is not in use? I replaced the one in my iPhone, no trouble at all.
