Ryobi Lithium+ HP 3.0 ah Battery Update and New 1.5 ah Battery

Even though we had early pictures of Ryobi’s 3 ah compact Lithium+HP batteries, we are now learning that the compact 3.0 ah P191 was just a picture of a what may have been a prototype. Although a 3 ah compact would be great, the real thing is a 10 cell fatpack. The fatpack batteries should benefit from better heat management and longer cell life as each cell will have to work less hard for the same output from the pack. At the time of writing the 3.0 ah P191 battery is sold in a variety of kits so there should be some good deals to be had. After reaching out to ryobi, they told me there was never a compact 3.0 ah battery to begin with, so the 10 cell version is the only one we’ll get, at least for the foreseeable future.

At the time of writing these batteries are not available individually, so here’s the description from the 2 pack:

Ryobi introduces a 2-Pack of 18-Volt 3Ah LITHIUM+HP batteries. These batteries feature superior electronics and performance to allow you to work stronger and longer with all 18-Volt ONE+ tools. These batteries deliver superior runtime, power, and performance when paired with Ryobi Brushless tools. They have a durably constructed frame for impact protection and have an on-board fuel gauge so you can easily check your charge at any time. These batteries can be paired with over 100 tools from Ryobi 18-Volt ONE+ lineup.

Ryobi P189 1.5ah battery

Ryobi has been updating their batteries to higher capacities and with that we can see they have a new 1.5ah battery pack on the market

The Ryobi ONE+ 18-Volt 1.5Ah Compact Lithium-Ion Battery features new and improved Lithium-Ion technology, providing the user with up to 50% more runtime compared to standard Ni-Cd batteries. Featuring Extreme Weather Performance, this battery can withstand frigid weather conditions and is engineered to deliver fade-free power for maximum performance.

  • Lightweight design for reduced user fatigue
  • Easily snaps into place and detaches with quick-release buttons
  • Recharge on any Ryobi 18-Volt ONE+ dual-chemistry charger (sold separately)
  • Any 18-Volt ONE+ blue or green tool works with any 18-Volt ONE+ battery
  • 3-year limited warranty


  • Voltage: 18v
  • Capacity: 1.5 amp hours
  • Charge time: 30 minutes (although which charger was used was not specified)
  • Warranty: 3 years
  • Price: $49.97 at Home Depot at the time of writing

My thoughts: the 3.0ah would have been great as a compact but a 10 cell fatpack can generally provide more power more efficiently. As for the 1.5ah it’s honestly a bit pricey at $49 but it may come down in the coming months. These both look to be great additions to the Ryobi 1+ line.
