Yuasa makes a lot of batteries for private labels. I had a sales rep come by with several different brands of batteries that had been sawed in half and Yuasa doesn't put as heavy of plates in the off brand batteries as they do the ones with their label. Their is a difference. Yuasa batteries usually go 4-6 years and the off brands are usually shot in 1-3 years. I replaced the Yuasa battery in a customers four wheeler back in the Spring that was 13 years old. That's the most I've ever seen.
