What to know before buying

Listing details to confirm

The listing's compatibility information is inconsistent: its broad compatibility claim includes RY40002 and RY40408, while another section explicitly says the battery does not fit those models. Confirm your exact tool and charger model before purchase. The 7.5Ah capacity and 200 g weight are listing claims.

Who is it for?

A good fit for

  • Ryobi 40V tool owners looking for a single replacement battery who can verify their model against the compatibility details.

Less suited to

  • Owners of RY40002 or RY40408 tools, which the listing explicitly excludes.
  • Buyers who need a charger included, as the supplied package details do not list one.

Aggregate ratings lean positive, with most ratings in the five-star category, but a smaller share are one-star and the distribution alone does not explain why. Treat this as a limited signal rather than evidence of compatibility or battery performance. For buyers, confirming the exact Ryobi tool and charger model matters more than the rating pattern.
