the problem with disconnecting the battery from atv, IMO is this
MANY of these new machines again, require good power at all times
,back to my hunting camp, several folks there , due to parking atv's in barns without power, would take battery;'s home for 2-3-7 months and bring back fully charged batter'ys
but what ended up happening(mostly arctic cat atv's) is the atv's computers would go bad, from NOT having power , or the power NO power deal
many of them ended up needing all new computers(ecu's or what ever) and were like new atv's, less than 300 miles on them, and all due to, pulling battery's over and over!
So, as for disconnecting the battery's when on a maintainer, yes it can prevent things from over charginga battery and damaging electronic's, but apparently so can NO having power to electronic's too<
double edge sword of sorts?
countless folks I know use battery maintainers for decades and never have a issue
but again, all modern machines these days have a ton more electrical items on the, so> hard to say what ifs the better option.
new battery is like what a 100 bucks every 5 yrs(about average on a regularly used atv) if NOT on a tender?
so makes one wonder, what is the better option? right??
