Hey Al,
Merry Christmas and thanks large for the battery class, it's slowly sinking in to my brain which resists charging normally.
So I am going to parallel my new Optima and my older big ol'  Trojan battery and charge them separately, so I assume that I'd better unhook the batteries from one another before I hook up separate chargers, right?

If the batteries are different type - AGM & wet cell you don't need to charge them separately all the time. But the wet-cell may need a periodic equalize charge.  Get a marine dual battery paralleling switch - A-B-Both-Off. Set it to "Off" and turn on your charger(s). That way you don't have to disconnect any cabling. You can also do the same thing with a couple of marine grade 50A 12VDC single pole switches.

Here's some charging configurations for those interested.

Happy New Year!
Al

When paralleling battery's, if the battery is the same type but different size it's Ok to use a single charger- but you need to consider the combined AH rating when selecting the charger size. F. ex. If paralleling a 100AH with an 80AH the combined AH rating is 180AH. Ideally you would want a 18A-36A charger. I would never go lower than 10% of the AH rating. Some onboard dual or triple bank chargers permit paralleling of the output to achieve higher output ratings, i.e. a triple bank 10A charger may allow the three (3) 10A outputs to be paralleled for 30A total. Check with the manufacturer before purchase.
