Good to know! thank youThe difference between computer UPS and Ecotech battery is:
1. Ecotech battery last longer despite it has generally smaller capacity than similarly priced UPS. That is due to UPS convert DC power back to AC to power an AC device.
2. UPS can power other AC pumps as well such as return pumps.
The best way is to use a deep charge marine batter with an convertor for backup.
