Hey Tim, I was lucky and got 14 UPS batteries from a change out at work, all 260 AH! and all good, they just change them every year for safety. But they weigh almost 100 lbs!

You are correct. In the scheme of things, the 26AH gel cells are not Large! (Most of the ones that I've used are in the 2-5A hour). Hence my indication that they are large! (Wish I had some 260AH) Thanks for the info - I'll set it for the 'Non' selection. As these are small compared to a 'normal' sized battery, the main purpose is to let the repeater stay on line till we get up & turn on the generator. Most of the time, the outages are only for a short while, so they ought to work ok. Thanks again!!
