Battery dies intermittently / at random / for no reason
I have owned my Alfa 147 Jtd for more than a year now and the strangest thing has been happening for the last month or so.
The battery is completely dead at random times. I took it to my local battery fitment center and they tested the battery and it is fine, according to them. Here are some examples of what goes wrong:
1: Been driving fine (average 50km per day) and one morning I used my remote to unlock the car which it did. But when I tried starting the car it had no power. Not even my dash lights came on. Had a friend jump start me and it was fine for a few weeks after that.
2:Started my car fine the one morning, drove 15km to work. Stopped at the shop and locked my car. Popped into the shop for 3-4 minutes and when I came out, I unlocked the car fine, but as soon as i tried starting it, the battery was completely dead. Not even the dash lights come on. Jump started my car and it was fine for a while.
3: Today tried to start my car, but the same problem. Jumped it and drove to work fine.
What is going on? Has anyone experienced something similar? It's very frustrating not knowing when next my car isn't going to start
