I am wondering if anyone here has serious experience about the workings of car batteries. I am quite knowledgable about auto electrics and mechanics, but I have a question.
My bros. car alternator in his VK for some time has been over charging the battery. The regulator 20 seconds out of each minute has been peaking to 16.9 volt and then going back to around 14 volt as normal. This has been happening for a while and I only traced the problem when he couldn't start the car and I jumped it and found this problem when testing with my meter. I did replace the alternator today and it seems to be charging as normal now.
Now the big question. Does overcharging make the electrolite evaporate in any way? Do I need to top up the cells? I am hoping that there isn't any battery damage. The battery is 5 months old and I think this overcharging possibly killed the previous battery.
Any advise appreciated.
