Blue Top Batteries

[Hotpepper]

I have a friend who was given 2 new blue top batteries, one brand new the other about a year old. Both need charging. A fast charge is required, tell me the best way to charge each, I have a 2/10/50 amp charger.

I have 2 of the 4 batteries in my boat are blue tops and I'll be adding two more this summer, and the only problem I have with them is they are 250$ each, other than that they are great

Why so expensive?
are they gel cell?

Make sure you have the time to keep checking those batts for overcharge and be wiling to accept 90% as full. Or get something like this Schauer CM16A Charger Desulfator and get a full charge with maintenance.

I know its not multibank but I dont need multibank and not willing to pay for convenience of a waterproof marine charger when the pigtail can stay connected to the single batt. I can plug it in when home without lifting a cover. BTW if fast isnt needed, the 6 amp is only $30-40.

who would pay that much for those? lol

Whats the voltage now? if they're pretty far down run it on 10a for a few hours then step down to 2a. lessen the chance to overcharge.
