Title: Battery charging question. Spruce or anyone else with the knowledge.
Post by: AuRavelling79 on September 22, 2025, 08:29:34 pm: Talking of a lead/acid leisure battery that is connected to the van alternator charging system.

Is it best - to get the longest life from it - to keep the battery from discharging below a certain point? As in should I trickle charge my leisure battery frequently and if so how often?

Each night? Twice a week? Weekly?

Could draw 30 amps but would flatten the vehicle battery on short trips so stick to 20 amps so leisure battery is always working fully charged on 14.2 Volts whilst van battery remains at 14.4 v.

Depleting it below a certain percentage uses a cycle & shortens its life.

Possibly use a battery to battery charger also to help top it up between jobs. We do on both vans.

the leisure battery after every use and to not let the battery drop to below 50% depth of discharge

I also have a b+b charger that charges up my 2 batteries when my engine is running.
