I love the little comment about thhe Hybrid cars. lol
But on a more serious note, the customers are Idiots. if a battery dies on you while driving, its either your alternator or belt that may have been stretched over time and is not the corrent lenght anymore and is causing possible slip at times and not charging properly. they probably left their lights on in the car. a bad battery will not become good after a charge. someimes a slow charge may give you another year, but once its low on amps its time to replace. I have a BMW and im a mechanic, I love listening to music in my car, and i hate wasting gas, so a few years ago i used to come to work, and listen to music with the car off.. I figured it would only drain a little power, and once i drove it later that day, it would just charge back up.. well i was wrong, listening to music 10 minutes every morning for maybe 3 months killed the battery. Im a great mechanic, so im told, so i figured i can just charge it.. well i did, it seemed ok, but next morning, there were not enough amps to get the car started.. for the people reading this and dont know about cars..(my car had 12.5 volts which is great, but it had about 100~CCA AND I THINK MY CAR NEEDS LIke 750CCA) so then i thought i need to do a slow charge, and when i got to work, i did, the battery got a nice 9hr chargem, it had about 500 cca, and 12.5 volts. so the car started up and i went home that day. guess what, next morning it was low on amps again so i just ordered a new batt. FYI BMW battery- $175.00 +tax, but after i got the new battery, it worked great.
If your battery is 2 years old and its dead, thats your fault for leaving on lights, leaving doors not fully closed which leave the lights on in the car. or maybe just listening to music with the car off. most likely though, it might have just been a belt or alternator, .
