Daft Leisure battery question
Got a 85amp leisure battery, fitted a voltmeter to it as well as a few 12v sockets
When it's all connected, but nothing plugged in, it measures 12.5 volts (Fully charged), as I connect some sockets (Fridge etc) the voltage drops......now here's the daft question.........."How low does it drop before I need to worry about it continuing to work" & "Will the voltage drop as the battery starts to run down and get flat?"
Sorry for the daft questions, don't really do electrics
Here's the set-up

Depends on what its powering. I have equipment that will bring a battery down to 5v but I have other equipment that will stop working at 10v.Dale

I'm with you (I think), so the Fridge had the biggest impact, but it will run on Gas eventually - and be plugged into the two socket electrics when towing eventually.
Ran lights, phone charger and water pump and it dropped to 12V - so I think all will be well Iggy/Ieuan

The battery should be around 12.8 volts fully charged with 10.8 being the lowest you don't want to go below as recovery to fully charged is affected
Some chargers will recover a battery from below that value but a standard lead acid battery does not like being continually taken below that
