Charging different types of batteries

[peterjaw]

Good day, captains,

There are different types of batteries, such as AGM, flooded, Gel ... etc. The manufacturers of those batteries claim different charging specifications.

If I have 2 types of batteries on my boat, AGM for starting the engines, and Gel for leisure, then do I have to install 2 chargers accordingly?
How do I know what type of the factory-installed chargers?

How do you handle this kind of configuration?

Do you actually have AGM and Gel at present ? If so, it is possible to charge both on the same charging regime, depending on the charger that you have, which you haven't told us.

I have 2 batteries: one AGM and one flooded.
My boat is Quicksilver 855 weekend, the battery switch is off/1/2/1+2 type.

Quicksilver gave me 2 flooded batteries first hand, and I replaced one of them with AGM according to the requirements of
the Mercury Verado outboard.

I can't locate where is the charger and don't know if it is OK for AGM battery.

If you have a flooded domestic battery, there is no value in replacing it with Gel. I'd stick to a sealed lead acid battery, or another AGM.

The mains charger should be in what Jeanneau refer to as the "plumbing compartment", it should be next to the mains consumer unit. Jeanneau fitted Cristec chargers as standard, which have DIP switches to change battery type. It would most likely have been set to sealed lead acid from the factory, which has a float setting that's a little high for AGM.

OK, I got it.

The charger has (or may have) switches to change the battery type.

Thank you very much, I will figure this out on my charger.
