KEMIMOTO Lithium Motorcycle Battery YTX5L-BS/YTX4L-BS, LiFePO4 Lithium Battery 12v 2.5Ah, Pre-Charged Powersports Battery, with 2 Universal-Fit EVA Spacers, Compatible with Motorcycle ATV Jet Ski

Package was so light I thought I was scammed. This battery i9s incredible light, but works great. have had one in my H2 SX for about 18 months with zero issues. Holds a charge really well even if the bike sits for extended periods of time. Highly recommend!

2 years and still going strong! I own a Yamaha Tenere 700 and MT10 that were due for some battery replacements a couple of years ago due to storage and lack of use. I chose the 12v 6Ah Kemi as the replacement for the ol led acid bricks. I was skeptical of the quality of lithium batteries from MULTIPLE horror stories I've read online. To my surprise these things hold up and help start the bikes WAY better than oem. Yamaha is not known for the easiest bikes to start, i can attest to this as my mt10 took forever to crank up, not anymore! The cold cranking amps on these batteries are a godsend as it is almost an instant fire up on the bike now compared to the old led boat anchor. I do track my mt10 on occasion so the lighter battery is also a major plus in my book. ONE thing to note, if you do decide to buy a battery tender (I haven't needed one since purchase btw) make sure its lithium compatible as the charge voltage will not be correct for these batteries. One more thing to note, these batteries will need to warm up in winter, click your bike on (do not crank) and let sit for about 1 minute, turn the bike off then crank it over. This is an excellent product that has held up in EXTREME heat and sub freezing temps for over 2 years!

Amazon says this battery wont work with my motorcycle. Its a Perfect for Indian Full Dress Bikes I have an Indian Roadmaster Darkhorse elite 2025 The Kenimoto YTX20L-BS with 12v 12ah and 960cca Has exact same measurements as the Polaris GZY20HL-C (4082949) 21.1ah and 320cca (knowing the difference between Ah and CCA is important to know what battery and why a battery will work for your vehicle is important) fits perfectly: started and stopped bike on and off rapidly 6 times and it started fast and smooth every time. Seems to charge right in the correct range while running, roughly around 14.3volts. I will see what happens with the next few trips and update. The reviews for Kemimoto are hit or miss I've had some things come in damaged but they have always corrected the situation. I personally like their stuff and at good value, plus customerservice has come through on the items that did work as inyended Come back for long term feed back installed Jan 5 will give a 1mo, 3mon and a 6mon update

Battery works, but I’m not confident in it lasting long. Battery arrived with 60% charge,no big deal because I already have a lithium battery charger. So I charge it to 100%. I tested the battery once it got to 100% charge. Battery only puts out 418 CCA, when the advertised is 480. This could be a problem if your motorcycle requires the full 480cca. The other problem, the battery tests at 86% health, keep in mind that’s upon arrival. So who knows how long it’s been sitting around before it was sent to me. It’s been a few weeks since I’ve had it, and while it takes my motorcycle a couple attempts to start, it does start. After a couple weeks of use, battery health is already decreasing and I’m now at 80% health. I’m glad I purchased the 3 year warranty because I don’t think this will last a year. Install was super easy, size was the exact same as the battery this replaced (antigravity battery). Customer service hasn’t been very good either, I brought up my concerns, and was told anything over 85% health is considered a good battery.

Smaller than ag battery. A good assortment of spacers are included to keep it from rattling around. Mounting post have multiple options (directions) you can attach.not sure how well or long it will hold up but I’m happy now.

It's light and works good, but connection isn't the same as a harley battery. You must bend the cable end flatter and the attach connection of the battery could be larger and attack screw could use a larger washer.

Didnt arrive like at first date but the battery is awesome came with pads to make up for the amount of space that was left over because the battery was shorter than the old one but fit like a glove and started my motorcycle like a champ . just placed on charger to bring it to full charge that only took 1 hour with trickle charge . The performance is unbelievable for the size. Just going to see how long it last the gel battery i purchased didnt last as long as was stated but we will see about this one thanks.

Got the batter for a 2015 Honda CBR500R. Battery came fully charged and with extra foam risers. Install was seamless. Iwould have preferred longer screws for the battery terminals though. I have multiple accessories on my bike connected to the terminal so would've been easier to connect for a longer screw. Install was pretty simple though. Didn't need the risers for my bike. No issues with my bike.

I purchased this battery after replacing the battery in my CRF250X with a lithium 2 years ago. The prior lead acid battery would lose charge quickly after attempting to start the engine more than 2-3 times (ethanol gum building up). The combination of adding a high quality fuel stabilizer, a JD jetting kit and adding the Lithium battery replacement has eliminated starting issues with the bike. I purchased this unit for my son's TRX400 to solve the same issues. Love the light weight. Just be sure to get a Lithium Ion compatible trickle charger for these units when in storage to avoid problems.

This battery fit perfectly and the fact that it is lithium and that it is lighter along with be able to go longer between charges if not used makes this a perfect cold weather motorcycle battery. I've had it for over a year and am loving it. Definitely recommend.

So far so good. I put it in a 2010 Ducati Multistrada S & it cranks it over with no issues. I also like the double posts. It makes attaching the positive & negative cables very easy

After 3 weeks of use, I am pleasantly surprised with this battery. I have a Harley shovelhead with a 32 amp stator, and it starts it up no problem.

Working well. With battery's its a long term game. Battery posts have threaded holes on the sides to be able to have the battery installed on its side.
