Urgent Battery Backup question

[kenman345]

I have a 6055 nanostream. I was wondering about the safety connector and how to get a long amount of time with it.

Tomorrow my house power will be off for an estimated 6 hours for a maintenance to the wiring. I have the safety harness and the powerhead, but no battery.

I have no time to order anything, but in the future might. I was wondering if I connect 2 6v batteries in series how long I might get from that. Also, is it possible to combine multiples of 6V batteries together to provide even longer time so that my tank is not without circulation for too long.

I will not be home during this downtime to swap out batteries or anything. Everyones advice would be much appreciated

EDIT:
Would something like this setup be what I want to do?

If so, how long might i expect from the batteries like these? http://www.homedepot.com/p/Energizer-Alkaline-6-Volt-Battery-529-TP1/100674598

If you wired it up exactly as shown you should get about 4 hours, to get 6, you will need 2 more batteries in that chain. I would not use a charger on the battery you linked to, you would need rechargeable lantern batteries to be able to use a charger, such batteries are used in deer feeders and available at most farm and ranch stores or sporting goods stores. Keep in mind rechargeable drycells tend to be weaker, usually 1.2V per cell instead of 1.5V so instead of 6V, you have closer to 5V as their will be 4 seperate cells inside, usually just banks of AA batteries, IIRC that battery you show has 32 AA inside it.

Personally, I would just use a 12V 8-9 aH SLA, this will get you 8 hours and is rechargeable. Batteries Plus or Fry's would have these, they run about $40. The 6055 uses about .8 Amps so the number of Ah is a little less than the number of hours it will run if the battery is fully charged.

Should I put the SLA in a box though? is that all I would need?

You would need a safety connector, 12V SLA and a 0.5 Amp trickle charger to keep it charged, I would house everything in a battery box.
