I don't agree...it depends on the charger...I have a Pro Tournament 150 by Pro Mariner...it has 5 amps per bank...but what it does is it puts the amps where they are needed..so say your starting battery is topped off after an hour..those 5 amps are then split to the other 2 banks..I have NO problem charging 31 series AGM's overnite from 50%
He said 5 amps per bank. He also said more than half drained. He also didn't mention the type of battery. Sure, you can add the 2 1/2 amps from the starting battery, IF it's charged beofre the TM batterys. I might be wrong, but the starting battery on my last boats always seemd to require more time to charge than my TM's on an average day.
Also, it is better for the battery to charge at the highest rate possible, up to a point. It's better to charge at 10 Amps than at 5 Amps. It's better to charge at 20 Amps, than it is at 10 Amps, AS LONG as the battery will accept that charge rate. If it doesn't, you will create heat at the terminals, and that will mean the rate is too high. Could happen with a 20 amp charger. Rare that it would happen with a 10 Amp charger.
I'll have the Guest 2631 10/10/5 chaarger on my boat this year. |
