Weize YT7B-BS Battery High Performance - Maintenance Free - Sealed AGM Motorcycle Battery YT7B BS For Yamaha ATV

This battery was easy to install and fit as expected. It had a good charge right out of the box and started up without any problems. It feels sturdy and has been dependable so far. Overall, a good replacement battery for the price.

2 year update: Well, the battery finally died. I went to restart my bike at a gas station and the instrument cluster was completely dead. Not dim-- DEAD. I thought my ignition switch had failed or I'd popped the main fuse. I keep a tool kit with me when I ride my bike, and 2 of the tools are a multimeter and a small, portable jump pack. The battery showed just under 10V. I'm guessing one of the cells shorted or died altogether. If so, there was no warning. It cranked and started fine 5 minutes earlier, then refused to start after I'd ridden to the corner gas station and filled the tank. Just like that, dead as a doornail. I jumped the bike and got it home. Now I'm waiting for another battery to come in. I would've liked to have gotten more than 2 years out of this battery, especially since I keep it on a tender/maintainer when it's parked at home (which is 99% of the time). Having said that, between the high vibration and the fact that my motorcycle's regulator-rectifier outputs something like 15.5V all the time (by design, according to the service manual), this battery has led a somewhat hard life. I also managed to run it completely dead once by leaving the key on, which was my fault and which is the kiss of death for lead acid batteries. In all, I got my money's worth out of this battery. This time around, however, I'm going with a more expensive Energizer battery. Why? Because the model I bought before is not currently available from Weize, and none of the other options look particularly appealing. The Energizer is about twice the price. Let's see if it ends up being twice as good. Original review below: The battery on my motorcycle died after a few too many deep discharges and extended cranking. It wouldn't hold a charge no matter what I did, and even desulfating it didn't help. It had lived its life and was now in the great beyond. If you've ever tried to buy a motorcycle battery, you know that the size designations are not always as well laid out as they are for cars. A bunch of fitment guides gave me conflicting info, and even Amazon's parts guide didn't show me all of the available batteries. Such is life when you own an old bike. I cross-referenced the number on my old battery (Yuasa YB14L-B2) to this battery. The price for this AGM battery was lower than I could find for a replacement Yuasa SLA (sealed lead acid, IE wet) battery, and WAY lower than just about anything from a local parts store. I double-checked the dimensions, crossed my fingers, and ordered it. As soon as the battery arrived, I put a battery tender/maintainer on it. I didn't know when I'd be able to install it and I didn't want a dead battery when I finally got around to it. The battery registered as fully charged on my tender. A voltage check of the terminals showed 12.6V, which also correlates to 100% charge. So far so good. I installed the battery about a week later. Installation was easy and all the included hardware (metric machine screws and square nuts) worked fine. I greased the terminals to keep corrosion at bay, hit the key, and the bike cranked and eventually started. The starter spun with no problems at all. I've put a little less than 200 miles on the bike in the last week or so and the battery has worked fine. Both cold and hot starts have been effortless. I keep the battery on a tender for peace of mind but I don't think I need to unless I'm storing the bike for the winter. We'll see how long it lasts-- bike batteries lead short, brutal lives because of the vibration, but AGMs are supposed to combat this. Time will tell. As of right now, this battery has been a good choice.

⭐⭐⭐⭐⭐ Excellent Battery, Perfect Fit, Outstanding Value I recently purchased the WEIZE YTX14AH-BS motorcycle battery, and I couldn't be more satisfied with both the product and the overall buying experience. The battery arrived much sooner than expected, securely packaged, and in excellent condition. One of the first things I noticed was that it came fully charged and ready to install, which made the process quick and hassle-free. The dimensions matched my original battery perfectly, making installation straightforward with no modifications required. After installation, my motorcycle fired up immediately on the very first turn of the key. The cranking power is strong and consistent, exactly what you want from a quality motorcycle battery. Based on my experience so far, the battery appears to be well-built, utilizing the proper internal construction and capacity needed to handle both everyday use and high-demand starting situations. In addition to the quality of the battery itself, the seller provided a smooth and professional transaction from start to finish. Fast shipping, accurate product description, excellent packaging, and a competitive price all contributed to a great Amazon shopping experience. Finding a battery that offers this level of quality, performance, and value at such an affordable price is becoming increasingly difficult. WEIZE has delivered a product that meets and exceeds expectations. If you're looking for a reliable replacement battery and want excellent value for your money, I highly recommend the WEIZE YTX14AH-BS. Purchase with confidence—this is a high-quality battery backed by a seller who delivers exactly what is promised. Highly recommended.

Update: They fully refunded me for the battery. Since I had a good experience with the first battery, I gave it four stars. My first battery lasted two seasons (MN so seasonal and brought inside and periodically trickle charged in winter). Second battery was bought April 2026. Was on a motorcycle trip and battery completely failed. Bought a new battery that was different brand and no problems. First battery was good value for two seasons but 3 months is not worth the cheap price.

Very very good batteries full of power an always comes FULLY charged never had a problem compared to other brands I believe these are the best budget batteries out there believe me I have ordered many to this point. an the box have small blocks like for Incase you need more height for different bikes and the design stickers are looking great now just YTZ10S-BS and not the name itself of the brand I love it thanks

My Road King needs the battery terminals to be flush with the side of the battery as the battery cables travel vertically to them. The terminals on this battery are inset (like most battery) so my cable cannot attach the way they should. Return shipping was too expensive to consider so I twisted and pulled my cables to “make it work.” I’m not happy about it but it was my mistake. Double check your Harley’s terminal location before ordering!

Just got it 4 days ago. Put it on a good battery/maintainer and it was fully charged in no time, so it was charged fully when sent out. It fit perfectly in the intended ATV and it fired right up. Time will tell and price was good. Battery well protected and packed well for shipping.

Works and is the correct size but the hardware is terrible. The screw barely reaches the nut and is very loose. I used some cardboard to hold it up in place then removed the cardboard after. The nut is very soft so it’s very easy to cross thread it. I was able to fix it but it took me a few minutes of headaches and fishing the nut to realize it wasn’t going to thread in anyway. This is when mounting on its side on a Yamaha fz07. So good price but it was a pain to screw in the terminals compared to the stock battery which can be done in 2 minutes.

Bonne achat

Size was too small for our atv....cannot send back either.

My wife Pacifica auto start stop was not working, removed old battery installed this battery and working like a charm !! 100% recommend this battery if you Pacifica is having same issue. Thanks to the guy with previous review who had same issue with Pacifica.
