Engine Battery Voltage (1 Viewer)

[Organplayer]

With the leisure battery showing a steady state of 12.7 to 13.8, and the engine battery showing 12 to 12.3v, do these figures for when the batteries are on "trickle charge" seem correct. I was concerned that the engine battery appeared very low voltage compared to the leisure battery.
I have never really checked the state of the engine batteries in all these years. Laid back attitude comes to mind dosen"t it.
Best wishes to all Fun members.

No the engine battery is either not getting any charge or the reading is wrong. Check the voltage with a meter at the battery terminals. If it was being charged they would both show similar with no load switched on.

Engine battery off charge and resting should show 12.6 to 12.7v

12v is technically flat.

Time for a new one i reckon or put it on a proper charger and see if it recovers.

Thanyou DPSUK 99 for your informative reply. Engine battery is six years old now so looks like a new one is required, but to make sure I shall get this one tested/checked first. Best wishes. Ed

Has it actually still got the balls to start the engine?

Yes Techno, it does start the engine even when the Sargent controller display shows 11.8 or 9v.Once again thanks for your interest which is appreciated.
(I did think perhaps the Sargent controller reading might be erroneous but I got the same reading from my little 12v plug in digital meter)
