2019 KIA Forte Battery Voltage
I am a conscientious person in that I take good care of my car batteries, checking the voltage once in a while, especially after frequent start/stops without continuous driving, to make sure the SOC is good.
Upon picking up the car from the dealer there's a receipt in the glove department stating the voltage was checked at a station, being 12.56V @ 25 degrees C. Being an AGM Calcium battery the optimal voltage should be around 12.7, so I checked the voltage myself to see what's the reading at the moment, to my dismay it was sitting at 12.25.
I didn't bother charging it manually, since the manual says you must disconnect the battery in order to charge it, instead I drove it a couple of times, already accumulating 500 KM so far. Today I checked it again, waiting for the cluster hood open indicator to shut off in order to get a more accurate reading ( it pulls the voltage down by 0.15V Approx.), it read 12.45. Wonder why the alternator couldn't charge it up to 12.6 at least.
My attempt would be to charge it to 100% using a specialized micro processor charger at low current since I'm aware that lead acid batteries like to be stored full for maximum life.
I've read a thread somewhere in which the Forte owner has to replace his batteries 3 times, dunno if it could be related to battery sulfate resulting from low charge.
Anyone else experiencing this issue? Love to hear some thoughts on this.
