Leisure battery charging

[MartianTom]

Okay, here's today's 'wet-behind-the-ears newbie' dumb question....

If I'm on an electrical hook-up overnight, will it charge the leisure battery in the same way (or better) as it would if I take the battery off and put it on a charger?

I'm assured that the electrics on my MH are set up to charge the battery on a mains hook-up.

Short answer,it should do.

Not always a cut and dried situation because some MH systems use a fixed voltage power supply - sometimes called a converter - when on EHU. This supplies all the 12V electrical equipment at around 13.7V and also provides some charging current to the battery. Give time, even a flat battery will be brought up to something close to a full charge condition, but the experts say, this sort of float charging is not as good for batteries that are heavily cycled as that provided by a good solar or three-stage mains charger.

Need a cheap digital multimeter to tell exactly what is going on. The usual traffic light battery indicators tell you almost next to nothing.

Details of the motorhome and the charger make and model would help get your question answered


[should never be necessary to remove the battery for charging]

Thanks, folks

Thanks, Tony. I haven't bought a charger yet, but will get a decent one because I think I'll need to use it a lot.

My problem is that I live on the top floor of an apartment building, so would need a massive mains extension lead to reach the MH - so I'll bring the battery indoors to charge it. It will also mean I'll have to chill the fridge down on the gas, but so be it. :rolleyes2:

Depending on how often and how far you drive the motorhome this shouldn't be a problem, with the control panel switched off there should be NO drain on the lesiure battery. When you drive the leisure battery will be given a charge, plus if you use hook-up it will be charged again! So unless the battery is faulty, has a drain on it or you don't drive it very far it should NEVER require removing from the vehicle.
