I have Trojan Lead acid batteries on my SM SULA. the
first set I owned lasted 7 years which by all account is
pretty good. The boat was kept predominantly in Northern
Europe and was was plugged into shore power throughout the
winter whilst ashore.
Sula is now based in HK and got a new set of batteries
(Trojans again) when she arrived. She is now in commission
12 months of the year being used regularly and rarely gets
plugged into shore power. It is obviously very hot in HK
for most of the year. the batteries have crashed after
only 2 1/2 years. I was somewhat disappointed with this
short life until I read the SM owners manual posted here
recently, which stated that 1 1/2 years would be the life
expectancy!
I was wondering what other
folks experience has been with their batteries. Sula's
have always been meticulously maintained, topped up and
left fully charged when leaving the boat after use.
