Given that there are no starting handles or that a push might just get a vehicle fired up these days, it seems best to pay attention to the likely life expectancy of a battery... It seems a good quality Advanced Glass Matt (AGM) battery might be expected to last for 10 years if it lives a life where it is either kept on a float charger/conditioner suitable for AGM if/when the vehicle may be laid up or irregularly used..

I suspect few vehicle electrical systems are designed for lengthy periods of lay-up, though some perhaps more able to do so than others..? It seems AGM batteries may be able to put up with longer periods of inactivity than old style wet led acid batteys...

Whether your new battery is AGM or not, and how considered it`s maintenance might be may well affect it`s longevity.

I think AGM batterys may be found to be fitted to a necessary fitment to vehicles with stop start programming..?
