Thanks for the explaination
The chart in the link shows the Lifelines at 1000 cycles at 50% discharge.
I have done what was described with a 660 ah bank which rarely goes below the 75% discharge. I do have the availability to get close to the 100% no with the new alternator and shore power master volt charger.
I kaois have been desulfating when neccessary at 15.5, but not for the whole 8 hours...maybe 6 as I watch the temp readings
I porabbly have paid more attention to batteries since I bought these than I do anything else on the boat it seems. My wife says I am obsessed with it.
When these finally wear out I proably will go to the gells if I still have Haleakula, as they are really inaccesable.
