RYOBI 18V ONE+™ 1.5 Ah Compact Lithium-Ion Battery
RYOBI 18V ONE+™ 1.5 Ah Compact Lithium-Ion Battery is rated 4.7 out of 5 by 93.
Rated 2 out of 5 by from Good and Bad I had a battery that came with a power drill and after 2 months of use it will no longer charge. This is the reason for my low rating. I have tried to call the warranty line with ryobi I twice and sat so long I had to hang up. 30 minutes plus. I have since purchased other batteries and had a good experience with them. When they do work they last a for a good amount of time with moderate use.

Rated 5 out of 5 by from My grass says thanks! So where do I begin? Pricing? Well for only 100 bucks a cordless weed trimmer, that was a good bargain. Than product handling and weight. Very very easy to use, buttons are a wonderful thing, I like how easy and user friendly it is to operate, none of this throwing out your shoulder just to start the device. Weight, well its extremely light, I'm 31 and I feel I could use this if I'm 131. Last thing I want to say is thanks, im happy with the product t, was happy with the warranty it came with.

Rated 3 out of 5 by from mediocre battery without charge indicator In my experience, these ryobi batteries are at a good price point, but tend to be short-lived and run down faster than others. they also have a tendency to go "bad", taking a limited charge or get deemed "defective" or unchargeable by the Ryobi smart chargers. I always buy extra batteries because they all fit the Ryobi 18+ line of tools. Only buy these small batteries if they are on sale or included in a kit. My preference is the 3AH and larger batteries.

Rated 5 out of 5 by from Accept nothing less The 1.5 Ah battery came with a kit, and it performs amazingly better over the 1.3 Ah battery. This seemingly small difference in rating significantly reduced my chances of overheating, and has extended my run time considerably. The 1.5 Ah battery should be the bare minimum at which you run a tool that requires more power than a flashlight.

Rated 5 out of 5 by from Long Lasting/Fast Charging These batteries are small and lightweight but are long lasting and fast charging. Make a huge difference compared to the old nickel cadmium batteries!

Rated 5 out of 5 by from 1.5AH battery really kicks for the money & weight I am very excited about these 1.5AH batteries from Ryobi. They have really upped the value to price ratio. I am very happy to say that this powers everything from my Ryobi Jigsaw to my Ryobi Impact driver. This lasts and really shows the power that Ryobi has put into their products. You will not be disappointed. the 18v ONE+ platform is the best out there. I am a return buyer for these products. Thanks guys!

Rated 5 out of 5 by from Small and compact The 1.5 ah. batteries I use mostly on drills or impact drivers and they work great on other Ryobi tools with more power drain I have 3-4-9 ah. batteries and they all work great.
