I use battery minders for all my SLA batts and also my golf cart batteries (in my motorhome)
Best part is that you can leave em connected indefinately, and I noticed that the charge from the batteryminder seemed to last longer (electric scooter) than the regular bulk/float chargers.
Watch cheap sla chargers, they tend to float at a voltage that is too high for em, and they get cooked. Once cooked, they NEVER work right again.
Would +t ya, but alas I can't yet.
Enjoy the charger!
