I use a smart charger, and normally I will monitor the power into charger, and when it drops to 2 watt which is 0.1 amp I know battery nearly charged, I will wait a little longer and when I open bonnet want to see volts on charger over 12.8 volt, which confirms fully charged.
The charger will often alternate between 0.8 amp and 0.1 amp at the end of the charge a few times, the charger will switch to 0.1 amp when volts hit 14.4 volt, and return to 0.8 amps if the volts drop below 12.8 volt, it starts charging at 3.8 amp, then drops to 3 amp but not really interested in the first to stages, it is when battery is fully charged which is of interest.
The Kia Sorento is parked at bottom of the garden, to far from house for one extension lead, so I charge the Honda Jazz at the same time, and use the bonnet space of Jazz to protect the extension lead plug and socket. The net result is I don't charge the Sorento very often, so this time Sorento battery 95 Ah was under 12 volt when put on charge, far lower than normal.
So this is the charge rate as the Sorento hits 14.4 volt and first drops to 0.1 amp charge rate, and you can see twice an hour the charge rate rose to 0.8 amp, and a few days latter this is the charge rate where it goes to 0.8 amp 7 times an hour, OK only 1 minute long each time, but the voltage is now dropping faster than when it first started to pulse, which seems wrong way around, in the past the time between the 0.8 amp charges as increased as battery became more charged not not decreased.
The Jazz battery 35 Ah has stayed at 0.1 amp and the volts have slowly risen to 13.8 volt, and in the past the Sorento has taken longer as bigger battery, but has also risen over 12.8 volt with just a 0.1 amp charge rate, so a little puzzled as to what is going on.
