They worked OK, but the best batteries we have found so far are the gel deep cycle that are used in very large UPS systems. They weigh 110 pounds each and are rated at 120 amp/hour and they do that for sure. We actually have a site out of power right now that has been running on two of those batteries for 14+ hours so far and still shows another 8 hours remaining. This is with three wireless radios, an HP 24 port switch and a power rebooter all running off it. :) Travis Microserv Mark Nash - Lists wrote: > Ah-hah! I'll give this a try.
