I'm getting a bigger unit - SmartUPS XL 2200 - and I'm looking at batteries. I have an Interstate Batteries and Batteries Plus near me so I'd like to go with either of them.
This will be indoors. I'm aiming to get 280 watt hours (70 watts, 4 hours) of run time. Is there any idea as to the inefficiency of the whole AC/DC/AC/DC process? What type of battery would be best? Should I look for 12/24/48v batteries or does it matter (besides having to connect them in series)? Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373
