18V ONE+™ High Capacity Lithium-ion Battery
18V ONE+™ High Capacity Lithium-ion Battery is rated 4.6 out of 5 by 43.
Rated 2 out of 5 by from Didn't Last Long Bought a Ryobi String trimmer with the 18v lithium ONE+ battery about a year ago. I used the trimmer about 5 times, and used the battery in my Ryobi drill twice. Now the IntelliPort charger says the battery is no good. It will not charge. I dont see the sense in spending $50 plus on a replacement battery, that I will use less than a dozen times.

Rated 1 out of 5 by from POOR BATTERY LIFE Have never had good life with these batteries. After about 1-1/2 years they fail to hold a charge very long, even when setting on the shelf. There must be something better!

Rated 5 out of 5 by from Long life So far so good. The extra capacity ensures I don’t have stop in the middle of using the blower. This one also holds the charge when not using. My old original ones would die after one use with the blower and if I did not charge it hours before they would be dead when I went to use them.

Rated 5 out of 5 by from Reliable and Affordable Power! I own DeWalt, Milwauke, Ridgid and Ryobi 18V-20V cordless tools and consider these brands among the best in the indsutry. However, when it comes down to cordless tool options, innovation and affordabilty, Ryobi can't be beat. $ for $ the Ryobi 18V One+ 9.0Ah batteries can't be beat for power hungry tools on remote work projects.

Rated 5 out of 5 by from Long lasting, quick recharging! Bought these battery replacements for my aging drill batteries. I worked on a new metal roof with lots of screws and the new battery didn’t disappoint! Lasted for two days! Supper impressed! Waited for the ryobi days sale and was able to get a free tool as well with the purchase. Ended up buying two!

Rated 5 out of 5 by from Umm.....Awesome! All of the Ryobi tools and batteries are awesome! You cannot compete with the value over cost on any of the tools they sell. I use my Ryobi power tools, lights and batteries on a daily basis as a professional electrician and farmer and have yet to be disappointed. Great product, great company!!

Rated 5 out of 5 by from One+ system is so helpful I have about five of these batteries for my steadily growing power tool collection. And the One+ battery system has been invaluable. This will be my go-to from now on should their products continue to be this economical. Many companies should have thouth of this decades ago.... (Milwaukee)
