Generac 12V Battery For All Standby Models (8kw and larger Generators)

Product Overview

Keep power going in any situation with the help of the Generac 0H3421S 26R Battery. Every standby generator requires a battery to start the system, and this handy product is the ideal power source for the job. This 26R generator battery is just what's needed to ensure that the system will power up every time. Each one weighs a little over 70 pounds and is a heavy-duty item that can be added to a current generator. The Generac generator battery is a very useful item to keep the home up and running during a power outage or other emergency.

Was ordered with the 22kw generac

Emailed them asking where battery was?was emailed back.Was told it was out of stock and I was refunded would have been nice to have been verbally contacted

Brandon Tolle
never received order

they never sent order

Nightmare to deal with this supplier

I have ordered the generator and battery together. Up to now(two months) I still didn't receive the battery. I have called the customer service and trucking company over 20 times. I still don't have any conclusion from them. I emailed them to cancel the battery order and need my credit back. I still don't receive their response. Need to call consumer affairs to complain if I can't get my money back. Never order from factory pure again.
