No wonder the major players are dropping AGM batteries.
I bought my hyundai a couple of years ago at two years old, it has ISG.... the stupid auto engine stop start system.
It worked for the first year, though mostly I turned it off, but then it stopped working altogether.
Off to the dealers to book it in under warranty and they said at the time it would be the battery. I had my doubts as I had no trouble starting at all.
Anyway, circumstances dictated I had to cancel and never did rebook but just recently Ive had a couple of long runs and it started working again for a couple of times.
I decided to bench charge the battery.
First attempt.... 15a charge rate, 3 minutes showing full charge and capacity of 50%.
Second attempt... 2amps charge rate overnight so don't know exact time but showing full charge and capacity 70%.
The battery is obviously failing and not accepting a proper charge but the slow charge has kept the ISG going for maybe 15 cycles so far.
I haven't used the car for a couple of days so I'll see what it does tomorrow.
I can live without ISG so it won't be getting a £200 battery until it won't start on the key.
