I bought my truck in September 2014 so actually just short of 3 years. I guess still not to bad for the climate but as stated by others, I'd expect a much longer life back in the UK.
Possibly one thing to consider where my truck is concerned, I do quite a lot of small/short journeys just into Lam Plait Mat town so possibly a factor.
At any rate, the final death of the battery is probably in part down to me as I did run it complete flat a few months ago through my error leaving the camera plugged in and expected to have to change it then.
Battery now replaced. I went to gets price from Ford first. They quoted 4,100 fitted so rather than mess around I just said go ahead. Factor in the free coffee, cake, biscuits +Free fuel system cleaning treatment, tyre check and washer fluid top-up I'm probably about even money wise but have a like for like exchange Ford Battery. Only 12 month or 30,000 warranty (whichever first).
Davu. I'm also not a great lover of the idle/stop feature they put on cars these days. Must ruck doesn't have it. However from a safety point of view I've often thought that maybe not a bad feature to have in Thailand when at traffic lights. That slight delay in moving forward does allow for the opposite direction light jumpers and cut in front of you bike riders to get clear. I have kind of trained myself to count slowly to 3 before moving when I'm at the front and the light goes green. You've got the auto system.
