I was in WalMart (Canada) the other day and they are selling "Gel" ATV battiers for $89 Canadian. That's $62 U.S.
I remember those maintenance free, spill free Gel batteries costing almost $200 at the dealers. Its a "EverStart" brand but that's ok I have use the normal $40 acid types before and they lasted a good 3-4 years in my snowmobile.

 

I'll have to remember that when it's time to look for a new battery.

 

the gel cells are pretty much a standard now and can get them any ware. iv had good results with them. Canadian tire brands stay away from 2 failed in a year just after warranty. my dealer carries a cheaper brand that i got cheaper than walmart with better warranty

 

local wal mart here changes atv tires for $5
