Charging Battery with Alternator - Warning
This is a moderately discharged battery hooked up to charger.
(1) Charger attached and dialed to bring voltage across battery to 14.2 Volts. Current draw was around 35 amps.
(2) As current did not drop after a couple of minutes, I manually turned the charger down to get 13.3 volts, 8-10 amps
(3)45 minutes later voltage has come up to 14.4 V, yet the charge rate is down to 5 amps.
When that battery charger was new it had a temperature probe to place in a battery cell. It would have automatically reduced the power if the acid started to get too warm.
