High-capacity 20 V lithium-ion replacement battery

This 6.0 Ah lithium-ion pack replaces original Worx 20 V batteries for trimmers, hedge trimmers, blowers and other outdoor tools. It fits models including WG151, WG155, WG160, WG163, WG251, WG255, WG540, WG545, WG890 and WG891 as well as part numbers WA3511, WA3512, WA3520, WA3525, WA3575, WA3578, WA3732 and WA3847. The cell chemistry is lithium-ion and the voltage is 20 V.

Slide-on pack design with CE certification

The battery uses the standard Worx 20 V slide-on interface so it clicks into the tool and charger without adapters. CE certification confirms the pack has been tested to match OEM electrical and safety requirements. A user manual is included in the box.

6.0 Ah capacity extends run-time per charge

The 6000 mAh rating provides longer operating time between charges than lower-capacity packs for the same 20 V platform. Buyers who need a smaller, lighter pack for overhead work or who use tools that only accept compact batteries should look at lower-capacity options instead.
