Don't waste your time buying cheaper batteries or those with fancy logos. These batteries have never failed me and can easily last 2 to 3 years, even in the hot Arizona desert. The last battery I purchased cost $38 and lasted only seven months before it died. When you're out in the middle of nowhere, it's important to have a reliable battery so you can start your motorcycle or whatever device it's installed in. These batteries are dependable, and I've bought several over the years. Read more
I purchased this same battery over 8 years ago for my Yamaha R6 - 2011. Needless to say, this is an excellent battery to purchase. The key is to FULLY charge the battery before installing. Voltage should be somewhere in the range of 13.1 to 13.3 volts before installing. IF the battery ever falls below 12.7 volts, it should be charged again. In all cases. use a 12v, 1 amp or 12v, 1.25 amp charger. NEVER fast charge a battery of any kind. Heat build-up in a battery is 'bad'. I expect this battery to last over 8 years as well. If you purchase a quality battery and take care of it, this is a better deal. Read more

I bought this battery as it is supposed to be the OEM brand for my motorcycle. At first everything seemed to be fine at instalation and it cranked the bike right away, however about 48 hours later when I went to use the motorcycle it would not crank at all and the battery was completely dead. I thought I might have left something on the bike that might have drain the battery but it was not the case and the battery would just not charge anymore not even one bit. Even my old battery would keep a bit of a charge but this one doesnt. I thought I might have just gotten a defective battery so I tried to replace on Amazon but found out that the item is not returnable so I was refered to the manufacturer. Then I called Yuasa the manufacturer and they say that they do not sell on amazon or directly to consumer so they would not provide any support. So I got stuck with a dead battery, luckily Amazon came trough and refunded me so I could buy a different brand. Read more

OEM battery replacement for my bike, at a good price. For those saying the terminals are reversed, remember this is a sealed battery. You can lay it on its side (so the logo/text faces up). This effectively "reverses" the terminals wrt to the orientation of the bike. My bike's cables are routed so I had to place the battery with the logo/text up. Read more
