I really like the idea of battery backups and with the recent threads about power outages and disaster prevention I thought I'd start another thread so as to not derail the other discussions. I'm wondering what other people are using for battery backups, brands/models preferably and how long you expect them to run what equipment. So many battery backups I'm looking at look like they hold pretty pathetic charges and won't run for more than a couple hours under the load of like even a relatively efficient 80 watt return pump. For example the BRS ones say they'll run a Koralia 3 for 8 hours. A Koralia 3 only consumes something like 7 watts and the backup unit costs $180. That just doesn't seem very cost efficient. Icecap claims their battery backup for the vortechs will run one pump for 30+ hours and a vortech MP40 uses 12-40watts of power depending on the power level it's set at but it doesn't have an outlet for a regular power plug, just a connection to plug into the vortech driver. Does anyone know of good battery backup systems? I'd like to at least run my AC3, my network hub and my internet router for a while like David G mentioned in his response to disaster prevention, and it would be nice to have a battery option for my return pump too to run for a day or two but I don't know what can handle that load for 24-48 hours. Generators are not an option since I live in an apartment.
