About this product

This Westinghouse 20V 4Ah lithium ion battery powers all Westinghouse 20V lawn, garden and snow tools purchased in 2024 or after. Power indicator shows charge status. Run times vary depending on the machine, activity and conditions but the W20V4AH fully charges in 2 hours or less by sliding into our dedicated Westinghouse chargers: the W20V2AMP charger or the W20V2DP dual port charger (each sold separately). Just plug into a standard 120V outlet. All Westinghouse batteries are designed to protect from over-discharge and over-charge for longer life and have a 2 year limited warranty, so the W20V4AH also powers peace of mind.
