Charging battery at home

[dp]

I wonder if I just plug in the camper using my home 110 would it charge the battery if the batt were dead? Just curious.

According to LL if you plug it into the shore power outlet the converter will charge your battery. At least on the newer trailers. I don't know if it will if your battery is fully dead.

Ive run my battery dead a few times and have pluged the trailer in to a 110 outlet and it charged the battery back up

Yes, it will charge it up. But it is very bad for a deep cycle battery (or any lead acid battery) to let them die.

When a battery is completely discharged, or even discharged to 50% or less, sulfate precipitates out of the electrolyte. If it is immediately recharged it mostly goes back into solution with just limited harm. But if it sits there for days, weeks, months then it develops a hard layer on the bottom of the battery.

This hard layer is very difficult to put back into solution when you recharge. This means that you have permanently lost much of your battery capacity. If the layer builds up too high it will short the plates and the battery is then junk.

So don't routinely discharge your battery more than 50%. And even at less than 50% try recharge within a few days so the layer doesn't set up hard.
