[QUOTE="Tanzini, post: 354145, member: 9349"] I used to get these through work for insane prices (read: 35-45 dollars) and so I've accumulated somewhere around seven of these things. I've had them for about four years and they handle fine for me. They seem to charge faster and the AGM batteries are supposed to handle vibration better. Generally, the 55 amp-hour batteries would about six hours on windy days and fighting current. The 75 amp-hour would last all day. For the money, their specs aren't that great. Most I've seen are "dual purpose" and tend to have the exact same specs as a standard battery in similar size. What trolling motor are you running? I think most 12v systems typically draw around 45-55 amps at full power, so at that rate a small capacity battery would only last about hour or so. [/QUOTE]
