I am the owner of a 19 year old lanos sedan. I have this problem on 10/10/2017:
I was on vacation for 3 weeks and I returned on 10/10/2017 = the car has not been used, it is not in a garage - it is outside. I didn't take the battery home
The battery I have is: 60 Ah, 540 A , my father says he is "new", so I assume he is 5 years old
I took the voltmeter readings. Unfortunately, I only have it after firing, because I did not have a voltmeter before firing - make some measurements? Is it enough information that the protector indicated 12.8V when I disconnected it when it finished charging? I don't want to fire it today to get to work tomorrow :P
Measurements - given in order of reading:
-After starting the car and driving about 10 km in medium traffic jams - 13.3V
- after turning on the heating and rear window during gassing, 13.4-13.5V
- after turning off the heating and rear window during gassing, 13.9 V
- the car fired, without gassing, without turning anything on inside 13.96 V
My question - replace the battery? Is the alternator not charging it?
During the week I travel to work 14 km one way.
I have been using the car for about a year - the battery has never been discharged, it survived last winter (2016) without any problems.
Did I damage it with this 3-week break and the fact that I did not charge it but fired it from someone?
The car has more and more defects and I am thinking of scrapping it. If it is a battery, I will buy a new one, but if I buy a new one and it turns out that it is an alternator, I think that investing in this car makes sense and I will lose a new battery. Such disparities. I would be very grateful for your help
