    Under a car bonet is about the worst environment possible if you want a lead acid battery to last a long time. Very cold in winter, very hot on a run in summer.  If the battery was kept in a temperature controlled environment they would last much longer.
    We have had UPS battery banks that still gave over 80% after 25 years, but they were in air conditioned rooms.

    Is the boot the best location for the battery in most front engined vehicles? Less temperature variation (and more weight to the rear if that matters).

    My current car, a five year old BMW Series1 has the battery in the boot. So did a BMW 3 series I had for about 14 years from 1996.

    I can't remember where the battery was in the VW Golf I had between those two cars or in the Golf I had prior to 1996.
    A man walked into a car showroom.
    He said to the salesman, “My wife would like to talk to you about the Volkswagen Golf in the showroom window.”
    Salesman said, “We haven't got a Volkswagen Golf in the showroom window.”
    The man replied, “You have now mate".
