Let it snow, this battery will go: The Westinghouse 24V 4Ah lithium-ion battery powers all Westinghouse 24V cordless snow blowers and snow shovels (sold separately). These batteries will also power all 24V SnowJoe battery operated snow blowers and snow shovels. Power indicator shows charge status. Run times vary depending on the machine size and snow conditions, but the W24V4AH fully charges in less than 2 hours by sliding into our dedicated Westinghouse fast chargers: the W24V2AMP fast charger or the W24V2DP dual port fast charger (each sold separately). Just plug charger 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 W24V4AH also powers peace of mind. Just clear your path and enjoy the snow.
