These are excellent and yes you have to add the acid and let it absorb n then trickle charge over night as well as snap the seal cap on. There are pre activated batteries from yuasa that you jyst plug n play but, honestly I prefer adding the acid and charging it. Knowing it hasn’t been sitting on a shelf activated for 2 years. My last one went for 4-1/2 years heavy usage and is still going but, if I forget to turn lights off it has been dying so before I get stuck having to bump start it again I ordered another for my Z900 2019. I wouldn’t buy anything besides yuasa to be honest.

I live in a hot and humid area. Motorcycle batteries usually last 3-4 years here due to the heat. This Yuasa battery lasted 2.5 years/30 months before needing replacement; it always plugged to a Battery Tender Jr trickle charger when not riding. I will buy a premium AGM or Li-Ion battery from a local automotive retailer, with extended warranties, instead of having to buy this product off Amazon so often.

Easier to fill than I feared. My scooter starts 1st time every time like it used to. Not sure how long it will last, but I'm optimistic it'll do the trick long enough to justify the price. Time will tell

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.

I had 2 of these and both lasted 4 years. The original one that came with the bike lasted 2015-2018. The replacement one just died a week ago effectively lasting 2019-2022. Both died differently. The first was dying slowly and gradually with the starter turning slower and slower every time. The second died momentarily with the starter not turning at all just a day after working smoothly and then the lights went completely off after a few attemtps to charge it.

At first I thought it was clearly a knock off. Made in Taiwan. Lots of Chinese writing everywhere. Not a returnable item. However, since it wasn't returnable I filled it with acid, charged it, and put it on my bike, and it started my bike at 40°F wayyy easier than it ever has before. I then rechecked the Yuasa website and it says it is indeed now made in Taiwan. We'll see how long it lasts.
