Bessacarr E630, Leisure battery, brand new 110Ah. Terminal volts about 13v ish Just got back from 1hr run from the dealers. Put on EHU and charger reads 14.4v 17A according to the panel, voltmeter confirms 14.4v ish at battery terminals. Stays on this rate for about 5hrs then goes to float. Next day, reconnect EHU and same ritual. Although battery is fully charged, charger still pumps out 17A indicated on panel and 14.4v on battery for another 5hrs before going to float.
I haven't got a clamp on ammeter to confirm the current levels but can hear battery gassing away merrily when on boost.
My question is this right? Presumably if I keep connecting EHU the battery will keep being cooked even though not requiring any boost voltage, certainly not for 5hrs at a time. Is my charger faulty or just a dumb charger that bangs out max amps for 5 hrs then goes straight to float. I don't think the battery will last too long with this constant overcharging if I don't manually control it. Am I expecting too much? Surely the battery charger should sample the terminal voltage and reduce the current as the charging procedure is progressing? Any Techies confirm it is a faulty charger?
