Providing double the runtime of our standard 2.0 Ah Power Share battery, this 4.0 Ah version is for bigger yards or tougher jobs. When you need twice the juice to get that project done, this is the battery for you. It powers everything on the platform: Saws and leaf blowers, drill/drivers and trimmers, lawnmowers, and nail guns. So, theoretically, you could power your entire Worx Power Share collection on just this one battery. Think of the money you’ll save. Max Lithium-Ion technology makes for a lighter, longer-lasting battery than other designs. They won’t wane or drain, and you’ll get a full charge every time you fill it back up on the charger. Previous versions of rechargeable batteries would suffer from the dreaded memory effect, which would prevent them from fully recharging as they got older. Not these. You’ll get a full charge all throughout its lifetime. This battery is intended to be used with the following chargers (not included): WA3742, WA3868 quick charger, WA3875 dual-port charger, WA3878 dual-port quick charger. Whether you’ve been on the Power Share platform for years, or you’re just beginning your collection, you’ll save money and be free from the cord. Stop paying at the pump, or getting snagged on trees, and enjoy the cordless power tool lifestyle.
