AlanM January 29, 2020 Share January 29, 2020 From time to time we get members wanting to do a battery backup for their 12V aquarium components. I came across this website which lists prices for lots of different battery (and hard drive) combinations and allows you to sort by dollars per kWh of storage. https://battprices.com/?battery_types=sla&condition=new Pretty cool, and there's an AGM 12V battery that would probably be great for keeping some aquarium powerheads up for quite a long time with 1200 Wh of capacity for 180 bucks.
