batteries . . .lack of quality

[Richard5]

I would agree with Costco for batteries if they will fit the requirement.

For those complaining about batteries and failure, are you sure there isn't a slow current drain coming from something?

I think the best thing for seasonal equipment is the master switch cutting the power at the battery

Very good advice, modern equipment has so many parasitic draws, it is a must to disconnect batteries, or maintain them during the off season.
I have a quad battery which must be close to 20 years old and still going strong, charge it occasionally during the winter, use it every day all summer, most ATV batteries barely last more than a season due to going dead all winter.

Costco batteries have been good for pickup trucks
Deer batteries ok lots of trouble with interstate batteries and won’t buy them anymore

What brand of automotive or agriculture batteries have you had the best luck with, back in the 70's and 80's deere batteries would last 8 to 10 years, since most manufacturing went overseas, kitchen appliances and battery life is about half. Sad.

AGMs. Pay the extra. Worth every penny.
