Backup Battery

Hi there, just wondering if anyone has any suggestions on a reliable backup battery for a 29 gallon tank. We have power outages occasionally each winter here. Any help is welcome.
Thanks

Try a UPS (ininterrupted Power Supply) that is made for computers. They are designed to keep a 400w computer going for like an hour (more or less pending on model). Running two 20 or 30 watt pumps will last several hours. So, I would keep a powerhead and skimmer pump on that so when your power goes out, they keep running.
