Leisure battery charge

[ncmcdonald]

At the weekend I got my leisure battery wired up on split charge relay and wired it to power the cigarette lighter sockets and the interior lights. The radio I assume is on the same fuse as the cigarette lighters presumably so this is always lit up.

Checked the voltage of the battery this morning with a multimeter and it showed as 12.3 volts after the run to work it was 13 volt. I use the bongo every day so is this a reasonable amount of charge. I am not to sure how much is being drawn from the battery overnight and if I don't start her up every day presumably it would draw more. Does this sound right.

Thanks

should not be a problem mine is the same way. i think it can go down to about 10/11 volts without a problem.
but i stand to be corrected.

All sounds fine to me dude. I have a digital voltmeter on the dash which allows me to monitor LB voltage and what it tells me is farily baffling i.e. resting voltage when charged may be 12.7v or 13v, jumping to as little as 13.7v on charge to as much as 14.7v. If given a charge from a 240v charger, it may sit at nearly 14v immediately after charge but reduce to 13v or so without any current draw. There must be many things that cause all this. Battery temperature, load on battery, load on car charging system affecting surplus for battery charge etc. etc. But as DBO says, its not game over until the voltage drops below 11v or so (11.2v for my low voltage cut-off device).

I'm suspicious of the AmpHr claims for leisure batteries. Mine has never come close in real world scenarios

Et tu Brute? I've been thinking the same of late.....

Will you contact the Trade Descriptions people or shall I?
