Well, i'm just about having kittens. It occurs to me that before I bought the car, it was sitting in the compound at work for about a month. I went and looked her over, started her up with no problems, then locked her up and handed back the keys. Three weeks later, I buy her, move 'er on over to our side of the compound, still starts with no trouble. That's after three weeks of not even being looked at.
Now, after I left all the interior lights on and drained the battery, I can't get it to hold a charge. I had it on a battery charger in the workshop at work yesterday for just over 4 hours. I then cruised around for another 3 hours after work. Parked the car up at 11 last night. Got in this morning, and yet again the battery has lost charge. It has enough juice to crank the engine slowly, but not enough to fire up.
TBH, I have a sneaky suspicion that the batt is either the original, or the second it's had. It's a mopar battery, can't remember the part no off by heart but it looks almost as old as the car.
Should I buy a charger first and give it a real good charge. Or should I bite the bullet and get a new one.
