Larry,

How would you count a charge / discharge cycle according to this
article? When I use my two paralleled AGM's to start my little 15 hp
diesel, is that a cycle? I don't see how it could be since I sail
nearly every day during the summer and my batteries ought to be nearly
dead now. If the battery is good for 200 cycles and my draw down is
only 10% (In reality, it's probably less than that since my engine
lights of almost as quickly as a good car engine) can I expect to get
closer to 2000 charging cycles?

I feel even better about leaving my batteries in the boat now. Thanks
for the article.


Roger, starting a 15 hp diesel probably takes less than 80 amps for 20
seconds. This is less than half an amp-hour, probably less than one
percent of the battery's capacity. Mere noise in charge/discharge cycle
space.
