Costco sells their lead-acid marine batteries for $80.00. I bought their $170.00 Optima Blue-Top with a $40 off coupon for $120.00. Since I want a battery that's maintenance free, doesn't give off flammable gas, won't put holes in my pants, won't need a tray or box, charges very quickly, can be discharged lower with no damage, and can go right right inside the vehicle with me safely, the extra money is more than worth it, and I'll never buy another lead-acid over an AGM for my camping applications.
Don't have a Costco around here so I looked on the Advance Auto parts website. The cheaper group 34 blue-top is $240 minus the 30% off coupon that's on the internet is still $168. According to Optima's website, this battery is only 55ah. That's a hard sell when two Walmart 115ah cost the same as one Optima 55ah.
