The longest lasting one I've had was 14 years (Vauxhall Astra), which was pretty good going. The local motor factor's here say that seven years is about average. Most of mine have lasted between 5 and ten years so that fits. However, I think the Exide one on the Chummy did very well to last 10 years, given the far from optimum electrical conditions it was subjected to! That actually died very suddenly. Fine one day, sluggish the next, totally dead the next. Car batteries do seem to be a bit of a lottery!
