Questions & Answers

How can you determine the age of the battery for warranty

How can you determine the age of the battery for warranty
Asked by: DepotBoss
For warranty purposes, your receipt should verify when you purchased it. You can determine its age by looking at the serial number on the bottom of all Ryobi batteries and tools . It starts with 2 capital letters. The first 2 numbers after those letters are the year, and the next 2 numbers are which week of that year the battery/tool was produced. On a 40V 5ah battery I have, those numbers are 1932, meaning that battery was made the 32nd week of 2019.

Yes. I've been using mine for several weeks and the charger that came with the battery works better than the older style charger.
