low battery should i be worried

[timb]

my monitor shows one battery low .but I'm sure I left the battery switch on both. so the voltage should be the same. I haven't been there in 3 weeks.
pic from phone next.

13.44V is abnormally high for a battery off the charger. 12.71 is a normal voltage for a charged battery with no drain or charge.
If the charger was working then 12,7 would be low so we dont have all the needed data.

Do you have solar panels?

Shore Power OFF (If true someone kicked out your plug)
Batt 1 (Within bounds for a charger on Float charge. Maybe the power was just lost)
Batt 2 (Nearly full charged but not being charged. No way its cross-tied to Batt1 with a battery switch on BOTH)

the shore power relay is not installed yet(I should have mentioned that). so it may be charging one battery .it has a very old 20 amp duel charger. no solar.
I was going to wait until Easter to go, but if I can get this weekend off I'll go.
I think the 32 year old battery switch may have failed .

Is their a load on Battery 2? If not, it should be fine for quite a while even if not being float charged.
