Re: Battery education

The VW Beatle's battery was also located behind the seat but the engine was
at the back so the battery cable to the starter was as short as possible to
minimize power loss.  In general, at least on cars I worked on for the last
40 years, the battery is always located on the same side where the starter
is, as close to it as possible.  On my 1968 Dodge Van the battery was behind
the passenger seat, because the engine was between the driver and the
