Without warning, my car battery seemed to have failed a couple of days ago. The car is a 2016 Seat Leon FR Technology ECO TSI (although I call it JeffThree). I started the car with a little charger pack, after initially putting the clamps on the wrong teminals “Doh!”. I took the car for good 30 minute run along a few junctions of the M25, keeping it in a gear of two lower than I would normally, so as to keep the revs high, on the understanding that charging is better with higher revs.
When I got the car back home, after about 25 miles of driving, and went to start it again, the panel stated “12v battery low. Drive to charger” or something similar. A couple of days later, it now states “12v battery almost empty. Infortainment system will be shut down”. When I turn the key, i just hear rapid clicking.
Now I don’t mind buying a new battery, and it is due for a service anyway. I just don’t want to get ripped off. Checking the prices for batteries ranges from £70.50 to £215.00. If it is the battery, what are the factors I need to consider please? I’ve noticed some stating 70Ah and others stating 110Ah, which I presume is Amp hours, but cannot remember what that means, or if a lower number is better than a higher number or vice versa.
£200 for a car battery sounds excessive. I’d rather buy an £80 battery with a 2 year warranty than a £160 battery with a 4 year warranty, or is that the wrong way to think?
Additionally, if I remember correctly, batteries don’t generally go wrong, but it is the charging system to them does.
There were no warning signs of the battery loosing power. I didn’t leave any lights on. The car is regularly used. I bought the car in may 2016 with 3580 miles on it, it has now done 35500 and I’ve had it regularly service only by main Seat dealers. This car is a “stop/start” one, where the engine cuts out most of the time when stationary, and quickly restarts. I’ve never had a problem with the restarting.
