Winter storage of battery

I have one of those rotary switches on the earth terminal, and switch it off when it goes in the shed. I still put it on the charger every 4-6 weeks.

Hi Brian, Disconnecting is not a bad idea. It ensures that there is not some unrecognised load and is protection against faults.

Then either leave it permanently connected to a multi-stage charger with float function or give it a few hours charge once a month.

Left alone to discharge is death to a lead-acid battery.

I do exactly as you Brian.
In this case not the van but three vehicles left at home, batteries connected (for clocks etc.) and a 24hr. timer with a charger at each battery.
2.5a. chargers, timed for 2hrs/day.
Come home and all systems ready to go.

I do nothing.
My solar panels and regulator just take care of it.

My 3 van batteries all stay connected when it's at home but I turn the 240V charger on a few times a week (if convenient) - I have a small solar panel permanently connected too (the van cover blocks the main ones out) - overall, I've taken the advice that batteries should be full as a goog all the time, for a longer life.

Hi Brian,
I disconnect my batteries from the van circuit and switch to shore power (240 feed from shed). I have AGM batteries.
I then top the batteries up with a multi stage charger about once each month.

Flooded cell batteries lose about 4% of their charge per week. (car batteries)

AGM batteries lose about 4% per month. According to the information I have read.

Keep them, quote, "full as a goog" and you can't go wrong.

Cheers, Bruce.
