Default Batteries - what's best and cheapest for long term cruising thesedays

Seems like you have programmed it for too small a battery? You did check
the correct number of amp hours and if the monitor asks for a c/20, c/10
or c/5 value?


Well I put in the nominal ah for the c/20 rate. But it could be that
the batteries are conservatively rated. The monitor manufacturers
suggest testing the batteries at a high rate and then a low rate to
get real numbers. I've avoided that as it can't be good for the
batteries to run them flat twice or more (a single test is likely to
have errors) and the numbers will change as the battery ages... All
in all that seems like a high price to pay to have a % remaining
number. I already know if the batteries are doing what I need.

Anyway, I'm very happy with my AGMs and I'm glad to hear that you're
happy with your tractor batteries. *


Not tractor, more like forklift ;-)


Oh darn "cruizhimers" strikes again. I knew it was one of the "T"
words... Sorry
