Pyalong,
the figure RC140 referrs to the 'Reserve Capacity' of the battery and is an extremely decent number, even compared to Deep Cycle batteries, so what battery is it ??
You have stated "The
fridge temperature ranged between -4 deg and +4 deg, with the daytime outside high temp of around 21 to 22 deg. The car was out of the sun for most of the day"
That is a very large temperature range and in normal use would equate to the
fridge running far to cold and hence drawing too much
battery power, a figure of a minium of +1 degree and a max of +4 degree's would be ideal, as it would give you far better battery performance and the contents would be still very nicely chilled.
World Health Organisation and indeed most health authorities specify +4 degrees as absolute _maxium_ for safe food storage, and to have a temperature range that achieves +4 degree's but then goes down into the minus numbers you are only wasting
battery power! the temperature sender should be looked at to achieve zero or better still +1 degree, with a _maxium_ of only +4 degree's.
With the
fridge filled with food and drinks and the contents pre-chilled, run the test again I think the result would be slightly better.
