I use lead acid batteries on SM243 and get about 2 1/2 years out of them.  Make sure your charger isn't cooking them with too high a charging voltage when they are full...that happened to me with my last set of batteries and had to replace the charger.  Was lucky I didn't have a fire.'

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.
