Review: It works - It’s a battery! No issue with my ‘03 R1. Installed on 6/19/2026. I’m not a wet cell fan when there’s AGM composition, but this was what I had to get when I needed fast availability. It’s the standard Yuasa battery. Factory fit. Nothing derogatory to say. I charged it slowly & installed. I’ve had no starting issues and I use a battery tender to keep it warm. Pricing wasn’t an issue either.
Review: Does it Work on a 2012 Ducati Hypermotard 796?: YES! - Just bought a used 2012 Ducati Hypermotard and noticed it sounded ‘weak’ when starting. Sure enough, it had a ChromeBattery installed which was about 35cca short.. and the battery was dying. It would start very weak after being on the charger all night. I read these Yuasa’s work great but, being honest, I’ve never filled a battery before, so I was a little apprehensive. I followed the written directions, with one deviation. I removed the tape covering the holes on the battery, removed the acid tubes from the box and removed the black cap from the tubes. I then put the battery on a level surface, took the acid tubes, tipped them upside down and lined up the holes so the tubes’ male filler ports fit down into the battery’s female filler holes, make sure it’s level and press down. I tapped the battery a bit and observed acid from each chamber flowing into the battery. Once the tubes were completely empty (15 mins), I let it sit for one hour with the filler cap off. This was the deviation the written directions didn’t call for but it will extend the life of the battery. I then gently placed the filler cap over the holes and charged it for three hours with my 3a charger. Once charged, I disconnected it, let it sit 30 mins and tested it with a multimeter: it read 13.27 which was terrific. The Hyper fired perfectly the first time and has the right amount of cold cranking amps to ensure it starts the way she should. I’m very impressed with Yuasa and will def be using them again if/when the need arises. For those concerned with filling the battery yourself; don’t be. They make it really simple and it seems to work very well. ***UPDATE*** A few days after install, I took an 8 hour ride with multiple stops and the battery had zero issues - I'm VERY pleased.

## Questions & Answers

**Q: Does this battery come with the acid in the tubes?**
A: The bottle in the background is an acid pack. It is 6 tubes filled with acid so that when the customer is ready to activate the battery, they fill the battery using the acid pack bottle. This allows customers to store the battery on their shelf for some time prior to using it. It reduces the need to charge the battery on a regular basis. -- Mark (Lake Champlain Batteries)

**Q: Clarify Battery dimension: Yuasa says: 6" x 2.75" x 5.125" which is correct. Amazon says:7.8 x 7 x 5.5 Huh?**
A: Yuasa's dimensions are correct.

**Q: Can you ship battery to africa via dhl ??**
A: We only ship to the United States. Please call 30-879-9910.

**Q: Will this fit my 2005 ducati st3. amazon says no. my dealer says yes?**
A: Yuasa YUAM6212B YT12B-BS:Amazon said it would not fit my 2006 Ducati Monster S2R but it fit perfectly. In fact it is the original equipment battery as supplied by Ducati for my bike. I would check the dimensions but I suspect your dealer is correct.

### ⭐⭐⭐⭐⭐ True and Reliable Battery Performance and Capacity Claims
*by K***N on May 30, 2024*

Enough of meaningless statements about how good people feel after spending money on a product! Let's get to the real facts. As an owner of a few Yuasa YUAM6212B YT12B-BS batteries and a battery analyzer, I can share some measurable details. In the four attached pictures, you can see voltage and current graphs of the discharging and charging processes for two batteries. The first battery was used on a motorcycle for slightly less than a year, while the second battery has been in service for over six years. All tests were conducted at reasonable temperatures between 20 and 25 degrees Celsius, with no overheating during the processes. The batteries were fully charged according to the vendor's specifications before the tests. The first battery exceeded capacity claims by over 10% (11.06 Ah) during the discharge test. Judging by the graph, it could probably show even better results, but I stopped the discharge at a high cutoff voltage of 11.5V to avoid stressing it more than necessary. The second battery, after six years of service, still performs reasonably well, with a capacity loss of about 14% (8.62 Ah) from the nominal capacity. I have replaced it with a new battery to avoid any bad surprises. The new battery's performance was even better than that of the first battery, but I don't have the files handy. I might upload them later.
