Battery charge

I have installed two 6 v batteries in my Jayco. I now should have more lasting 12v power. Now to be sure I am leaving with a full charge in both batteries what should I do. I have a 12 v charger with 2 amp or 6 amp settings. Should I let it charge at 2 amp for a few days, or 6 amp for a few days. Thanks Stan

Doesn't your charger shut off automatically? I would use the 2 amp setting, the slower the better.

I would look at a small charger like a Battery Tender. They will keep your batteries topped of and will not overcharge and can be left on indefinitely The type of charger you are talking about sounds like one I have and is probably not a "smart charger" --- it will damage your batteries if left on 24x7 for long periods.

What year is your Jayco? What model converter/charger do you have? Your inhouse charger at 45amps would do a better job than the smaller charger in topping off your batteries in that period of time unless you can't plug in your unit and are bench charging them. A 24 period on 6AMP should suffice on a new battery.

Hi stans02, You have a trickle charge feature on your charger, which in days gone by was the best option. The Battery Tender, as Terry described above, is a better option. It provides a small, constant, and measured current (called a float charge) that will keep your battery(s) fully charged and keep them from sulfating. There are several different brands available. I have a Black and Decker that works fine, and costs about $20.

I use a 12V product called the "BatteryMINDer" (#12117) because it also has a desulfator feature that enhances the life of the batteries. Check around, I have seen it sell for around $35.
