Toyota Prado: Poor battery life

Generally I have found car batteries last me up to about four years but late last year I replaced my Toyota Prado battery after just over 11 years. After an RACV jump-start at the airport I went to my local Toyota dealer and asked if I could buy another Japanese battery like the one fitted. But it seems that sort of battery is not available here. Also, I have five jobs that require batteries — tractor, motor mower etc — which under normal conditions last four years if I am lucky, so I rotate a diagnostic charger on these all the time, which turns itself on and off as necessary. Do you think this really makes batteries last longer and should I also use it on cars if left for a week or so without use, as I do?

The quality of new-car batteries does seem to be falling but it’s more about car makers trying to save money. In my experience a quality charger, like the C-Tek one I use for my Toyota HiLux, helps by keeping the battery in the best possible condition for a vehicle that’s not in regular use.
