I would not recommend using an RE battery for standby/back up use.</p><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">There is a similar problem that I have seen. People use 6 volt golf cart batteries in their motorthome and then stay plugged into shore power for long periods of time. I see premature failures from this type of use. A golf cart battery is designed to be cycled, not left in float service. Without exercising the battery by occasionally discharging it and then charging and equalizing, it is likely to fail early. My opinion is anecdotal but I'm convinced it is true.</p>
