Leisure Battery Not Keeping Its Charge

[Davevarty]

Hi.

I have just bought a Ford Transit 190 motorhome. This is my first motorhome.

I have disconnected the main battery and the switch for the leisure battery is off.

The leisure battery has not keep its charge after been fully charged and I am sure everything is switched off.

Help please!!!!

Welcome to the forum.

How long does it take to discharge?

Have you checked the battery voltage at full charge and then as it discharges?

Yes, welcome from "across the pond".

Leisure battery is a new term to us. Here we call them CHASSIS and HOUSE batteries.

Which is the leisure battery and how is it supposed to be charged? And, as Stuart asked how long does it take to discharge? Have you had the batteries load tested after fully charging to verify that they are indeed in good condition?

Normal means of charging over here are:

Chassis battery: Alternator with engine running. On a few, also charged from the converter or charger when 120 VAC is supplied from generator or shore power.

House battery: Alternator with engine running. From the converter or charger when 120 VAC is supplied from generator or shore power.

How old is the battery? After full charge, tested with a hydrometer and volt meter, dry case, disconnect cables and it should stay charged, 12.6 volts for several weeks.
