I have deep cycled mine about 25 times in the last 15
months and it shows no ill effects. I had planned on
installing an isolator if I had any issues charging it
with the stock auxiliary battery relay system, but
haven't had any problems even though I drive the van
daily.

By comparison, my last starter battery lasted through
about 8-10 deep cycles before it would only run my
fridge around an hour on a full charge.
