Review: Real Yuasa?? - The reason I say Real Yuasa is because Ive ordered a Yuasa from another seller and what they shipped was not a Yuasa. They claim the brand they shipped is the same as Yuasa and that the companies merged which is not true according to my local Yuasa distributor rep at my local moto shop. This battery was easy to match to my bike and arrived in perfect condition. Finish, fit and operation is great. Be cautious when adding the liquid. Yes the battery comes "dry" and you have to add the battery liguid and install the cap. When installing the cap, I placed the battery on a solid surface, covered it with a rag and used a light duty hammer to gently tap the cap in place. Start tapping it in place from one end to another to insure a solid fit. The cap fits very snug so it is not possible in most cases to pop it in with your hands. Highly recommend this quality battery ***Update after 3 months*** Battery didnt last long. Wont hold a charge even when putting it on a regular or trickle charger. Questioning if its a real Yuasa now. Ive never had this problem with all of the other Yuasas Ive purchased from my local shops over the years. Waiting for a replacement battery from Powersport Superstore going on 2 weeks now. Will provide an update for the replacement battery when received. *** Update after 4 months*** I've continuously tried to work with Powersports Superstore and they are now giving me the run around. Still no replacement battery. The original battery was either just a bad apple or they're selling fakes which I've run into before. I have 3-6 year old Yuasa batteries that are still working without failure on my other bikes. My advise is to go to your local shop if possible and buy a Yuasa battery. They generally buy direct from Yuasa and that way you know you're getting the real thing. ***Update*** Im happy to report that I received a replacement battery via UPS on 12/11 from Powersports. I will install and hope that this one lasts. I previously called Yuasa on 12/11 to see if they could help and they were extremely helpful. Although they dont warranty batteries directly when sold retail, they were a big help and offered some kind of assistance after I had the battery tested by an authorized motorcycle dealer. Good company and good customer service from Yuasa. I will definitely continue to buy their products just not online. Besides, they informed me that although you can buy batteries online, you cannot return them once filled due to chemical hazard and shipping restrictions (understandable) Bottom Line: There are certain things that we should just not buy online. Support you local shops.
Review: No need to look elsewhere for a quality AGM battery - Perfect replacement for my KTM 390 Adventure. Yuasa has been the gold standard of motorcycle batteries for decades. Ships dry, so there's no question of how "old" the battery is, no worry about how much life it has left. Adding the acid is as foolproof as it gets, anyone who finds it problematic shouldn't be maintaining and operating powersport equipment in the first place. Tap the caps into place and charge, simple as that.
