    That charger is a single stage "Bulk" charger, unregulated, and ramps to 17.3VDC. Not good for 5AH Sealed LA even at 500ma and will kill the battery with only a few charges, especially if you leave it on and forget it as it would take quite a while to charge a 5AH at 500ma. See my battery hear it sizzle...It's basically a expensive wall wart.

    If you want to charge SLA's you need at least a 2 stage and preferably 3 stage with sealed batteries. For ~$35 you can get a 4 stage charger that charges most types of batteries and will "tend" them, plus use it for other things too.

    My mistake, PJ. That was the first one I stumbled across while searching and, due to impatience, showed it. I should have taken the time to search my Amazon orders and locate the one I bought. Here it is...

    A bit more than $10 but still a useful item to have around the house and shop.
