Yes. Any Ryobi ONE+ 18V Lithium+ battery is compatible.
- Your P215K1 drill is part of the ONE+ 18V system.
- It works with all ONE+ 18V batteries, regardless of age or Ah (Amp-hour) rating.
- Higher Ah batteries (e.g., 4.0Ah, 9.0Ah) will provide longer run time.
- The drill's IntelliCell™ technology manages power delivery from the battery to protect both components.
IF THAT DIDN'T WORK: If an older battery doesn't click in, check for dirt or damage on the battery terminals and drill contacts. If it fits but the drill doesn't run, press the battery's charge indicator. No lights means the battery is dead and needs charging. If it has charge but the drill is dead, the battery may be faulty.
HEADS UP: Only use Ryobi ONE+ 18V Lithium+ batteries. Using non-Ryobi or modified batteries voids the 3-year European warranty and can damage the tool.
