18V ONE+™ Lithium+™HP 4.0AH High Capacity Battery
18V ONE+™ Lithium+™HP 4.0 AH High Capacity Battery is rated 4.8 out of 5 by 204.
Rated 4 out of 5 by from works good so far I have but only recently started buying these one+ tools, and so far everything seems to work well. I have one of the smaller Ryobi hybrid fans that I used one of these batteries on during a recent power outage that on the low setting ran for over 5 to 6 hours while only draining half the battery. Other more power hungry tools like the ExpandIT weed trimmer and 12 inch chain saw one of these batteries lasted 30 to 40 minutes, but ran at what appeared to be full power until the very ended of it's charge. I cut up two fallen trees with that 12 inch chain saw and only changed the battery right at the end, but I was cutting the limbs up into smaller more manageable sizes while I was going.

Rated 4 out of 5 by from Lots of power I recently purchased the 18V ONE+ Lithium+ HP 4.0 AH High Capacity Battery as a secondary battery for my Ryobi Brushless Expand-It Attachment Capable String Trimmer. The 4.0 AH High Capacity Battery has plenty of juice to get through the job and has a fairly short recharge time. Definitely a good investment

Rated 1 out of 5 by from Disappointing Product I recently purchased a Ryobi 3 gallon portable shop vac, the first Ryobi product I have owned. I am a woodworking hobbyist and use Festool and Dewalt products but decided to go with Ryobi because of its 3 gallon capacity. The vacuum works well but the battery is terrible! It won't hold a charge overnight. I would estimate the actual intermittent use time in a day is 10 to 15 minutes, not a lot of use time in a day in my opinion. If I don't charge the battery first thing the next day, it will die in about 60 seconds. My Festool and Dewalt batteries go weeks between charges. For the price I paid for the battery, it should hold a charge longer than 24 hours. Based on my experience I would not recommend this product.

Rated 4 out of 5 by from Great for big jobs I bought this battery to use with my Ryobi chain saw. The original battery would die after only about 15 minutes of run time cutting large, dense tree limbs. This larger, more powerful battery lasts nearly twice as long. It is also very heavy, so it is not without a sacrifice, but "tree trimming is easy", was said by no homeowner ever!

Rated 5 out of 5 by from Awesome battery I bought this battery about 3-4 weeks ago and I've been able to do a few projects with it and I love the battery for all of my Ryobi tools it's there when I need it and it's always fully charged because I bought that supercharger for it I would highly recommend this battery or to anyone and I would buy more if I had the money

Rated 5 out of 5 by from Turbo HP Battery! I replaced an older lithium battery with this new Lithium+ HP battery, and right away I could see and hear the difference, especially on my orbital sander, angle grinder and corner cat sander, also gave my impact driver more power. I am planning on buying the 3.0 AH 2 pack next! Love my Ryobi!

Rated 5 out of 5 by from Awesome 4.0 Ah Battery I purchased this battery 3 weeks ago of which this is the 1st Ryobi Battery. I am upgrading to the Ryobi tool system from the Black & Decker Matrix 20v Lithium System. So I can say that it has lasted w/ the 2 Tools I have currently: P770 6-gallon wet/dry vac & P4001 Drain Auger I absolutely love the built in 4-bar charge indicator coupled with the Dual Chemistry Intelliport Charger which charges the battery in 30 minutes. Awesome. I look forward to using this battery with some more Ryobi tools.

Rated 5 out of 5 by from 18V ONE Lithium Battery The battery came with the charger. I like this version because it is easier for me to insert and remove. It holds a full charge long enough for me to do the exterior of my 450 sq ft home. I like that it's also lighter in weight.
