9.0Ah 18V Lithium-Ion Battery

This 9.0Ah 18V lithium-ion battery powers Ryobi One+Plus cordless tools. It suits tradespeople and DIY owners who need longer run-time between charges on a single platform. The built-in LED indicator shows 25%, 50%, 75% and 100% capacity levels. Protection circuits guard against incorrect voltage, short circuit and internal overheating.

Replaces RB18L50 and P108 series packs

The pack replaces Ryobi RB18L50, BPL1820, BPL-1820G, BPL-1815, BPL-18151, P102, P103, P104, P105, P106, P107, P108, P109, P117, P118, P118B, P135 and P1820 part numbers. It is tested to work with the original charger. The jump is worth it when your current pack no longer holds a full charge or when a job demands the extra 9000mAh capacity.

9.0Ah capacity for extended jobs

The 9.0Ah rating delivers fade-free power in extreme jobsite conditions and all-weather performance. It comfortably handles high-draw tools such as rotary hammers, circular saws and angle grinders for longer periods. Runtime runs out on continuous maximum-load applications before the indicator reaches 25%. Builders needing multiple packs for a full day should plan for additional batteries.

Questions about this item

Does the 9.0Ah 18V pack fit the Ryobi One+Plus P108 and P109 battery bays?

Yes, it replaces RB18L50, BPL1820, BPL-1820G, BPL-1815, BPL-18151, P102-P109, P117, P118, P118B, P135 and P1820 part numbers.

How do I install it, and what step do people miss?

Slide the pack onto the tool or charger until the latch clicks; the LED fuel gauge at 25, 50, 75 and 100 per cent only activates after that positive click.

When will the lithium-ion cells need replacing?

The 9000 mAh cells are rated for hundreds of charge cycles; replace the pack when run-time drops noticeably or the four-segment gauge no longer reaches 100 per cent.
