I am getting rusty on my battery knowledge as I rarely work with them anymore, so here's a few questions for you battery gurus out there. In back-up systems with flooded batteries, I've always been told it's good to put them through several charge/discharge cycles when they are new to achieve rated capacity, then perhaps simulate a power failure to exercise them at some regular basis so they don't lose capacity by inactively sitting there at a float charge. Is this accurate information for flooded battery care in this situation?
What should be done differently for gell / AGM batteries in a backup system? Does regular exercise or lack thereof have any influence on longevity? Thanks.
