So recent get dealer to fix service light for star-and-stop system, and they found small battery defect and replace it under warranty.
But I am worry about the big one is also bad, the car 3 year and 45k km
So basically when I was commute 60km a day, the SNS system always kickin, and since about a year ago I WFH now, I only drive one long trip a week, the system rarely kickin as it always show charge battery, which is NOT BAD at all.
But, until recently service light for SNS is on and dealer fix it by replacing the small battery. Right after dealer work, the SNS can kick-in, as dealer wrote in their job order they charged both battery and found big one was ok and small one is defect.
But a couple of week after, now SNS stop working. During the week I still drive a couple of long 40km trip at least once a week, absolutely not to a point to sit car long to damage battery, so I am worried that big battery is just matter of time to die.
So I put it on battery maintainer overnight, it measured 13.20v with maintainer on, and once unplugged from maintainer for 30min, it drop to 12.48v, and I understand healthy battery should be 12.89v at full charge. Specifically I have two question:
1, is my battery still good given the measurement?
2, how did dealer get it back to a point of charge that SNS kick-in, how long my maintainer can get it back like dealer did.
