Mighty Max Battery YTX20L-BS GEL -12 Volt 18 AH, GEL Type, 270 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

I waited about a month to install and it cranked over no problem. Nice battery, being a gel cell it will be cleaner, no acid oozing out in the heat. An easy upgrade for my generator.

Service center wanted to charge an arm and a leg to replace my i3's battery (the 12V one, not the main one.) Turns out the battery is 100% proprietary (because... BMW), so you can't find it for a good price online or find it AT ALL at local shops, nor do any 3rd parties make one. Worse yet, rumor has it on forums that BMW's OEM batteries suck. They have poor cold performance and a short lifespan, despite the high cost. Well, after taking measurements and trudging through *battery after battery* manually, I finally discovered this one! Not only does it exceed the CCA and capacity of the original, but it even looks hella cool in the process. Amazon was sure to warn me this wasn't "compatible with my car," but I am not known for taking the conventional route. However, I am happy to report that aside from some minor tweaks to the BMW proprietary L-bracket(tm), namely several extra washers, it fits flawlessly, including the OEM battery terminals. I've had it installed for two months now and safe to say it's been working flawlessly. I am leaving this review for anyone who may happen to have an i3 or other BMW with the same battery in need of a replacement, because it certainly wasn't easy to find.

Was for sure worth the money. Lasts long.

lasted about 3 months before it stopped charging. I put it in my 4-wheel in October when it came in and I used it ~3 days a week until about Christmas and then I didnt use it for 2 weeks and when I went back the battery was dead. I didnt think too much of it, thinking that i had a battery drain because I could pull start the 4-wheeler and it would charge enough that I could use it the rest of the weekend. Until about a month ago when it stopped charging over 8v and that is not enough to start the bike.

The battery arrived and quickly well packaged. Out of the box fully charged with more than enough power to crank my motorcycle with ease. I can't vouch for the longevity of it yet but it looks to be well built. Straightforward installation fits pretty well, it is much smaller than the original battery that was called for. And I like that it is made in the USA.

Overall, this appears to be a quality battery for the price, and it fit my Harley-Davidson Sportster 48 without any issues. The reason I’m giving it 4 stars instead of 5 is because of the terminal hardware alignment. The battery uses removable nuts inside the terminal housing for both top and side terminal connections. On my battery, the side terminal holes did not line up properly with the threaded nuts. One side was off by roughly 1/16”, and the other side was off by about 1/32”. As a result, getting the terminal screws started was much more difficult than it should have been, and I was concerned about cross-threading or stripping the nut. This seems like a quality-control issue. A slightly larger or slotted hole, or better alignment of the captive nut during manufacturing, would likely solve the problem. Once installed, the battery started my Sportster 48 successfully, although the first start wasn’t especially strong. I’ve put it on a NOCO Genius 2 charger and will see how it performs over the next several starts. I considered giving this battery 3 stars because of the terminal alignment issue, but overall the battery seems well-made and I want to give it a fair chance. If it performs well over the next few weeks, I may update my rating.

This ATV battery works great and has been very reliable so far. It holds a strong charge and starts my ATV without any hesitation, even after sitting for a while. Installation was simple, and it feels well-built and durable. Overall, a dependable battery that does exactly what it’s supposed to do.

Got this for my 2020 Sportster Iron 1200. Easy to install, fits great, and turns over better than the stock battery ever did.

Bought back on April 5th and installed today. Was an exact fit for my '00 Suzuki VL1500LC. First start of the season ALWAYS takes a bit to get those two paint can cylinders moving. Was a little nervous when I found the Amazon box on its side, but the unit was well packed and unaffected by being on its side. Dropped this battery into position turned the key and she fired over w/o much fuss at all. Will keep on a battery tender whilst between rides, but overall, I'm pretty happy with this. If things go sour, I'll update. For now, I'm recommending this for the price and CCA (230) required for a large bore 2 pot engine.

Wicked product!! Comes precharged amd packaged very well. Slid right into my application (2014 Canam xmr 1000 outlander) .. bike fires right up now no hesitations. Replaced an oem that was 13yr old. Lol hopefully this one lasts!!
