should a car battery charger read 12.0v?or more?
i am wondering if my car charger is no longer efficiently charging.it
has a 6v and 12v setting. a test with the multimeter on the 6v shows 7.3v. on the 12v setting it shows 12.0 volts. now i read a car battery varies from 12.39 discharged to 12.6 fully charged. to add to my confusion, this charger has an analog ammeter which does register a current flow of 3 amps into the battery when connected. can a 12.0v charger charge a 12.6v battery? or is my 'open' reading by multimeter an incorrect way to measure voltage pressure available? thx |
