I have a question about the battery and first charge before installation. Today my new starter battery has come, I measured this precautionally and determined a voltage of 12.6 volts. Since I have read somewhere that the voltage of a completely full battery is about 12.75 I have connected a charger and now it has been charging for almost 7 hours and does not stop. The charger is a new ctek XMS 5.0 and should actually shorten the battery Have the most time fully charged what it doesn’t do Now my question is whether the new battery is already broken or is the behavior normal?
