Product Description

The P108 is the strongest battery in the Ryobi One+ lineup. At a whopping 4 amp hours, this has a long runtime, serving your needs through a variety of applications. Being the flagship battery for the One+ family, you can be sure that it will work for over 70 18V power tools from Ryobi. It also acts as a fuel gauge. At the push of a button, you’ll be able to see how much charge is left, so you can prepare other batteries as needed. The P108 also boasts one of the fastest charging times out of the Ryobi batteries. It can go from empty to full in as little as 60 minutes! Unlike its NiCad cousins, this lithium ion battery will not drain when not in use, so you don’t have to keep it constantly charging. Simply plug it into your tools when you need it, and rest assured in its reliability. Remember, Ryobi means power done right.

Third party vendors do not warranty beyond 30 days

Third party vendors do not warranty beyond 30 days
ADVISORY: Be careful when purchasing from a third party vendor and not Amazon directly; the three year warranty will not apply. I purchased this battery and charger to replace NI-CD battery that came with my original kit(which is allowable and compatible, according to Ryobi) in July '15, used successfully until April 2016, when the battery lost power, began to get hot, smoked and then died. So hot the housing around the contacts started to melt. So, this battery was defective in some way and the vendor third party amazon vendor will only allow a 30 day return policy. The product is good, just the warranty is not honored, which is reason for my low rating, Fortunately, Home Depot is having a spring sale on a two pack of Li-Ion batteries.
