Battery works
Basic battery for my 4-wheeler. Yamaha Big-Bear 400. Great fit. Worked as expected.

Does this battery work like oem?
I purchased a new “used” motorcycle to me and needed a new lightning box to get it started. I looked at many different batteries at big box stores and Amazon and came to this one. From not even needing dimension from my old battery I ordered this one for the cost and the fact it was a gel battery. Installation was simple although I wish it has threaded posts instead of the nut and bolt setup, but this was done in case your battery cables needed to be mounted on the side or top. First crank was great, as well as the rest so far. Battery has been in about a month and so far no complaints at all. Cca was just as expected and my bike starts with no issues. I would buy this again! EDIT 2 month update: after about two months the battery gave out on me. Wouldn’t start my bike after sitting for about a week. I contacted the company and they sent me a new one without returning the old one. I keep this on a trickle charger we’ll see if I got a better One this time

Didn't make it 1 year
Lasted less than 1 year. What trickle charged during the winter in my garage (winter wasn't even cold this year). Started fine in spring and used it for another month and now it won't hold a charge.

Good enough not the best
Great battery for the money but don’t expect it to last forever. I have to keep mine on trickle chargers, but they fit perfect. Start up the four wheelers and buggy and have decent power.

Excelente batería le quedó perfecto a mi Yamaha Virago XV700 1985, prende al llavazo! De principio al verla me dio la impresión de estar muy grande, pero al ponerla le queda perfecto.
