Monitoring battery level
« on: December 05, 2013, 11:12:51 pm »
Just following on from another post. Think this could come in handy for all of us really, battery indicator. I run my system off van battery, would be nice to know if i was running it too low then could start the van up. Think im gonna get one

I paid less for my gauges and they display the actual volts and not just bulbs. (From ebay)

According to some battery whizz, a leisure battery needs to stand for 4 hours before you measure the voltage to see exactly what state of charge it is.

So any gauges are at best an estimate if you take readings before that. Considering that there is very little voltage difference between a fully charged leisure battery 12.7v or over to half charged at 12.4v, reading a battery too early will give you a false reading. Especially is this so with a split charge relay connected where the van's alternator can be kicking in a voltage on 14.4v.

I monitor mine by trying to start the van - if ti doesnt start then its gone flat - if it starts then its ok. Tip always park on a hill.
