Starter Battery voltage.

[ontheroadagain]

I am slightly concerned about the starter battery on our new Adria.
It was fully charged a week ago and already it is down to 12.4V.
We do have an alarm and tracker fitted, which will be drawing a small amount of power.
We also have solar, but I understand that that it will only send a charge to the starter battery when the voltage falls below 12.5V.
There has been no sun over the past few days so it wont be getting topped up.
With our previous motorhome I could have left it for 3 weeks without charging it.
Do you think there is an issue with the battery?

When mine went down to 12.4 after 8 days I replaced it, not sure if it was necessary but not worth the risk with airbag ECU's falling over on low voltage.

No..
I think your battery is fine..
A week running a small constant load of maybe about 50ma when everything is shut down give or take ..Will bring the voltage reading down.. 12.4 v seems fine
If you have solar on the leisure..fit a battery master type device to the start battery.. that will take care of the small constant drain..
