What to know before buying

Listing details to confirm

Compatibility is model-specific. Compare the tool and charger model with the listing, including its stated exclusions, before purchase. The supplied listing is inconsistent about the replacement part number, citing OP40261 in the title and OP4026 in one feature, and its broad compatibility wording does not fully match the detailed model lists. Customer feedback also mentions size concerns and mixed charging and battery-life experiences, so confirm fit and charging compatibility for the intended setup.

Who is it for?

A good fit for

  • Ryobi 40V tool owners looking for a rechargeable replacement pack and whose exact tool model appears on the compatibility list.
  • Buyers who value an on-pack charge indicator for checking remaining power.

Less suited to

  • Owners of models identified as incompatible in the listing.
  • Buyers who need a replacement charger included. The package list names a battery and user manual, not a charger.

Customer feedback reports positive impressions of battery quality and value, but charging performance and battery life receive mixed reactions, including reports of packs that hold charge and others that do not accept a charge.

The listing's capacity and protection claims do not establish real-world runtime or charging results.

Negative themes

  • Some customer feedback reports size concerns, including a battery described as too large in diameter.

Mixed feedback

  • Charging feedback varies, with reports of good charge retention as well as batteries that would not take a charge.
