I got all my data from the Powersonic web site (www.powersonic.com). I just checked and they have a technical manual on the site. I never discharged by 12 Volt nominal gel cells to less than 10.5 Volts. Apparently they have improved their technology, but check their manual.. No, don't discharge them before recharging. Mine are still going after 10 years of light use. If you keep it watertight and don't let the voltage go below their recommended minimum (probably several drain cycles), they will last a very long time. Their 2.3 and 5.0 AH gel cells (I had both) seem to be good choices. Regards, Steve Pituch "Warner Family" <hmgwarner_at_shaw.ca> asked: > Do gel batteries have a memory?

I was taken aback at > the weight of some of these gel batteries. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
