Battery warranties aren't worth the paper they are written on, imho. Even more so, with batteries bought on the internet.
The local motor factors sold me a Lion battery for my previous van. It was sold with a 2 year warranty. It packed up after 18 months. We need to investigate the reason for failure. Send it to this address for evaluation. It will take7 days for this to be completed and doesn't include bank holidays and weekends.
What do you do in the meantime? This is why I always say that when it comes to batteries, especially leisure batteries, we best realize we take the risk, even if the failure was down to faulty materials and/or assembly/manufacture.
According to the sales guy at the motor factors, they rejected each claim that they received. He stopped dealing with them.
The motor factors wouldn't replace the battery until the manufacturer authorized it, which I can understand.
In South Africa, the same battery was sold with either a 2, 3 or 5 year warranty. The longer the warranty you asked for, the more the battery cost as the warranty was linked to an insurance policy. If the battery failed after 18 months when you took a 2 year warranty out, then they refunded you a pro rata percentage of the price against a new replacement. You knew what the pro rata value was when you initially bought your battery. This replacement battery didn't have a warranty attached to it. It seemed to satisfy us, but then we didn't know anything else, as that was the way it was always done.
Last year I replaced my van battery as I as dubious it would survive this past winter. It was the original battery supplied with the van as it had the Fiat assembly plant's name stamped on it. The van had done 106k and was the battery was 12 years old. I did think at the time I should have replaced it with the same Varta battery, but I didn't. I didn't know all this until I took the battery out to put in new one in.
