Portable generator batteries

Portable generators with an electric start mechanism will have a replaceable, rechargeable battery. The battery part number for a specific generator is listed in the generator's user manual or in its exploded view (EV) document. Use the online Product Lookup tool to locate a user manual for a specific generator. See below for a list of the most common portable generator battery part numbers.

Generac OEM batteries can be purchased from Ordertree.com. Simply enter the part number for the battery you need and search. Replacement batteries can also be purchased from Amazon, Batteries Plus, and large hardware stores like Home Depot and Lowe's.
