Energizer TZ10S AGM Motorcycle and ATV 12V Battery, 190 Cold Cranking Amps and 8.6 Ahr. Replaces: YTZ10S and others

Battery was delivered in Mar 2021 and installed in April. After 2 rides (within a week), bike sat for 2 weeks and battery mostly died. Charged fully w/ trickle and attempted to start 3 days later. Unsuccessful. Next day, I jumped the bike, rode for 30 miles (including highway); no stops. Returned home, turned off bike and attempted to restart right away. It did not.

Am impressed with the quality and charge state upon arrival

This battery arrived with only 10.5V of charge, *and* had a slightly bent terminal. I put a trickle charger on it for a couple days and got it to work, but it won't hold 12V for very long. I put in a return request here on Amazon, and was prompted to reach out to the manufacturer, since defective batteries aren't Amazon's problem. Fair enough. So I contact Energizer, and they tell me to contact Clarios, since the battery is really a Clarios product licensed and branded by Energizer. So I contact Clarios, and they tell me I need to go through Amazon for the return. But Amazon doesn't exactly have an 800-number I can call, and their return/refund prompts take me right back to the beginning of this circle of hell. If you want to take a risk and buy this battery, suit yourself, but you might end up with a heavy, useless brick that you just paid $90 for. Oh, and Clarios customer service couldn't have been more dismissive or less helpful.

The battery in my 2020 Triumph Speed Twin died ( quite inconveniently). I went looking for an AGM replacement. Even with the 3 year Assurance warranty it is cheaper than any other brand name competitor. Starts the British Beast right up 😁

Battery good work. Installing of it was little harder because move power culping around get it to work or tighten down terminal not right angle. Battery other that was good

What's there to tell? Does it fit my motorcycle? Yes. Did it power my motorcycle? Yes. Is it of top quality? It feels solid and no leaks - as good thing right? I did have to charge it up before installing, out of the box, it was at 45% charge. Cost? Well, batteries are inexpensive anymore.

Bought two of these batteries, one for my 2013 CBR500R and one for my 2013 CBR600RR. They state that they come pre-charged and ready to install and that is 100% correct. I have not heard those bikes start that strong in a while. I chose Energizer because its a solid brand and I have never been disappointed. It's a really good price too.

I deciced to move up in the price range for my motorcycle battery. With the 2 year extended warranty, i expect a lot of life on this battery. The only negative point when I installed it yesterday was the 2 nuts that came in the packaging DID NOT fit in the slot between the terminal posts fully so the bolt came in at an angle and wouldn't mate. I simply used the old nuts to my previous battery (which were thinner) and problem solved. I ride 2-3 times a week for errands and to keep the battery charged up. Hopefully, 3 years life out of this one

Purchased product on March 14 2024, Discovered the battery was defective (confirmed by purchasing a local replacement of the same size/specification). Can not return or exchange this product through Amazon or the Manufacturer. Very Disappointed, buyer Be ware.
