just purchased new van, batt says 12v on display in caravan, i understand 12.7 means fully charged, dealer says is fully charged on 12v, can anyone explain, do you get different readings onthe display in the van compared to if used a meter to read the battery terminal. thanks - andy
Meter on batt. can show as much as 13.75 when fully charged. (digital meter). But anything over 12 is OK. put it on trickle charge for 24hrs and check reading then.
