Review: Excelente
Review: Perfect. Powerful. Long lasting. Worked just fine with my Ryobi weed eater. Haven't tried it with my other Ryobi products, but I'm sure it will do just fine. This twin pack cost less that the single one I purchased from the big box store a couple of years ago. Since I only had the I wanted a back up for it. I do have three of the original small amp batteries that came with my drill, chainsaw and weed eater that still work and that I'll continue to use, but they do not last as long. Can't share how long it took to charge because I didn't time it. I just recommended putting it on the charger as soon as you get it so it's ready for the next day. By the way... Once charged it stays charged until you're ready to use it. Enjoy P.S. the green tags mean they're charged.

## Questions & Answers

**Q: What is the difference between this one and ryobi p122 (https://www.amazon.com/dp/b015qikgjk/ref=psdc_552354_t2_b07j5wjf1c)?**
A: The difference is more than the shell.  This product looks like the Ryobi P145 Lithium battery set.  P122 contains Ryobi Lithium+ which are better batteries.

**Q: Can i use the lithium battery on older ryobi tools**
A: Yes,you can use this battery with all ryobi tools and the blue one too

**Q: How many charging cycles can the 4ah battery go through before losing its charge capacity?**
A: This question should be asked to ryobi directly. To answer your question it depends on how and what you use the battery with. Every scenario and tool is different on how it drains a battery a small led light can lady maybe a whole 24 hours but a 18v shop vac can empty it in maybe 15 minutes so every tool is different.

**Q: Is it a P197?**
A: yes this is P197 which is the batteries shown in the picture
