Generator Batteries

The generator battery is designed to operate for a significant period of time. However you never know how long you will be without power. Having an extra battery will insure mostly uninterrupted operation of the generator no matter how long the power is out. In many cases this costs less than replacing the battery in your car and will be well worth the investment. Just make sure you check the generator battery regularly to ensure that it is in good working order and fully charged.
