18V ONE+™ Lithium+™HP 9.0 AH High Capacity Battery
18V ONE+™ Lithium+™HP 9.0 AH High Capacity Battery is rated 4.9 out of 5 by 132.
Rated 5 out of 5 by from Home run I've been hoping that Ryobi would put out a battery this big. I have big Ryobi battery tools that a battery with this kind of run time was needed. So awesome! I can now use less batterys in my day. I put this battery on in the morning & it lets me go all day. All though on some smaller hand tools this battery makes the tool weigh more. So that being said each person would need to judge for them self if the weight on smaller tools is ok. All in all this battery gave me everything i was hoping to get out of it. I am so happy with the battery.Would recommend to any one that owns Ryobi cordless tool.

Rated 4 out of 5 by from doesn't get rated Wh when drawing a larger load I just tested all my Ryobi tool batteries for capacity. I used a load tester running at 10A/12V regulated load . Ryobi 9Ah/162Wh P194 got 133Wh Vanon 6Ah / 108Wh got ONLY 58 Wh Ryobi 4Ah/74 Wh P108 got 55Wh Ryobi 3Ah/54 Wh P191 got 42Wh Ryobi 1.5Ah/28 Wh P107 got 19Wh Ryobi ?Ah/24 Wh P102 got 13Wh As you can see when you draw a larger load, the batteries don't stand up to the ratings BUT they are much better than the cheap knockoff batteries available on Amazon. This battery works great with my DIY Ryobi 18V One+ Powerstation which you can find on thingiverse or youtube

Rated 5 out of 5 by from Lasts Forever This thing lasts forever and is great for all day tool use. Perfect for tools such as the Ryobi radio to play music all day long or more power hungry tools such as a leaf blower or belt sander. I have been trying to run it dry but haven't had enough time to do so yet. Not overly heavy either compared to the other Ryobi batteries.

Rated 5 out of 5 by from Best value out there I bought this battery about a month ago right after I bought the p238 impact driver. I only had a few of the 1.5 AH laying around and they just weren’t doing it for me. This battery lasts an insanely long time especially when using a tool with a brushless motor. It’s a little bit heavy but it’s not too inconvenient to use. I used this with my impact to build fences and drill thousands of screws. I love Ryobi and putting them against the “big brands”, and my p238 with battery performs as well if not better than the Milwaukee m18 fuel impact. Ryobi just does a great job at creating value for everyone

Rated 5 out of 5 by from BIG and BAD Would I want to use this in a drill...absolutely not. However, this has been awesome for lighting, speakers, and my shop vac to name a few. I have already ended up using this way more than I expected. Love it!

Rated 5 out of 5 by from Ryobi 9.0 AH Best battery hands down! I have gone to the Ryobi 9.0 AH battery. Nothing else compares to the battery life this product offers. The 9.0 AH is like having 10 batteries all rolled into one. It works awesome with my outdoor mini fan, heater, which will now last for hours!! Ryobi tools and there 9.0 AH battery is the only way to go.

Rated 4 out of 5 by from 9.0 HP battery Overall, it is good. Adds extra pop to brushless tools and has excellent run time. Bit heavy, not gonna lie...but you will most likely be using this battery for heavy duty tool (not drill/driver). Biggest question mark is the classic stem connection...with the size and weight of this battery, and the power tools it's designed to power (vibration)...I question it's durability...already heard customers complain it's not staying in place and actually ruining connection apparatus. Ryobi needs to rethink this...must add additional support for battery to stay attached to tool

Rated 5 out of 5 by from WOW WOW WOW !! This thing is a beast I thought it would never run out of juce. I would love to see some in a two pack for my miter saw I believe I could run all day with two. I don't know what else to say about it. Be prepared for a little extra weight but its well worth it.. It wont fit in my pool vacuum but it works fine on the regular battery., however keep that in mind
