What to know before buying
- The listing says it replaces several Ryobi 40V batteries and names supported tools, but explicitly says it does not fit RY40002 or RY40408. Customer feedback also reports mixed fit and battery-life experiences, so confirm your exact tool and charger model and treat runtime claims as uncertain.

Less suited to
- Owners of RY40002 or RY40408 tools, which the listing says are not compatible.
