good battery for cheap price
Put this in my Sportsman that I use to plow snow with and it survived last winter with record days of -20 degrees. I'm ordering a similar one for my sled this year.

Great Value
This battery is a great buy. I expect it to last several years. All batteries require some type of maintenance and as long as you do it, the life expectancy increases.

Awsome Product
I bought this to replace the old part in my 1974 Kawasaki Z1900... works AMAZING!!!

Works good
I opened the box and I was surprised to find out that they are shipped dry. I looked online and, sure enough, the ad says they are dry. I just missed it.

You will have to take it somewhere to get it filled before you can use it.

Works good. Nice battery.
