Having said that I swear by my Powerall. Have started my own vehicle, my small diesel tractor, my ride on (not really a test) with my no probs. Have actually started more other people's vehicles than my own and that includes older 3l diesel utes.

However, if your battery is getting tired there is no substitute for replacing with a new one. Buy a jump start unit later on as a back up.

Just to be 100% clear this is not about my battery being tired - I have known good batteries in both 4WDs I own. This about being able to start a vehicle if you have a flat battery - because as you know shit happens ...
