Mighty Max Battery YTX4L-BS - 12 Volt 3 AH, 50 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

I purchased this for my atv, but it was way too small. This is a tad bit smaller than the batteries that come in solar fence chargers. It was the best value I could find so I kept it. I am currently using it for a self-made solar power generator. Not sure how long it will last in this capacity. But I will more than likely buy another own when this one goes bad. The battery will function in most capacities as it has the required nut and bolt hardware with it. Because of that you can rig it to work with most things to work with you can crimp connectors.

cheap and worked well

I ordered this without checking the dimensions or even really reading about it. It's installed on my 250cc cruiser motorcycle and cranks it right up no issues. Came completely charged an seems to be good quality.

In the end, I got this battery installed and it works fine. But it took forever to figure out how to get it installed, because of a simple but important design flaw. In my Honda Metropolitan, the battery goes in sideways in a compartment where you don’t have side access to the terminals. But there is nothing to hold the nuts in place inside the terminal, so it was absolutely impossible to get the cables affixed to the battery. Finally, after much experimenting, I figured out that a small strip of tape can be used to hold the nut in place, allowing installation. But it took a lot of frustration to get there. I’m not sure I’ll go OEM next time, because it’s so expensive, but I’ll certainly be thinking about it. Grrrrr. However, the battery fit perfectly, started the scooter fine, and so far so good. So I’m giving it 4 stars. But if you’d asked me yesterday, it would’ve been minus a hundred stars. If your installation is upright, in the opening, or both, none of this applies.

it's perfect in my 2022 Grom. perfectly drops into the existing battery compartment.

The battery works. This is my third battery for my scooter. They come charged, but don't hold their charge. I bought a battery tender for it and it does the job keeping the battery fully charged. The day I received the battery I put it in my scooter and it started. It was hesitant to turn over though. Its rated at 3AH, my scooter needs at least 4AH 5Ah, or 6AH battery to cold start without a problem without using the battery tender, but the sizes of those batteries are larger and may not fit in my bikes battery compartment. Anyways after leaving the battery tender on overnight it solved my issue. So if you do get the battery get a 20 dollar battery tender. I got mines from SHUMAKER and its easy to use. It comes with a connector and to connections. One is with the clamps, the other has two polarity ring that you hook up to your battery and leave. When you ready to charge you just connect the connector to the battery tender. This is so you don't have to remove the battery every time you want to charge it. The battery itself is ok. If you need a quick cheap battery this is it. I've had this battery and tender for two days and they work great. Honestly you might get 3 months out this battery minimum. I will update. The battery comes pre charged, but loses some of that charge from sitting in stock, so it would be good to charge it on a battery tender.

This one is great but if you do the whole package deal then this battery is great but the other one is so so small that it is not going to work for you

This is not my first Mighty Max battery. Unfortunately, it is the first that tested bad out of the box. As an OOB first step, I use the tester (pictured) which is rated for motorcycle batteries--and will match the type codes and specs for each battery. The initial reading showed a 57% State of Health (SOH) and indicated a need for replacement. Giving the benefit of the doubt, I put the battery on a trickle charger overnight. The next test showed 100% state of charge (SOC) and that the SOH was back at 100%. Trust but verify, right? The next step was to run a 5 minute waveform test back on the handheld tester, and then re-check the SOH. Again, the tester indicates a poor SOH @ 59% and need to replace battery. I reached out to Mighty Max via their web contact page and explained this situation in detail. It's been several days now, and no response. I also reviewed their warranty page for guidance. Buyer Beware--the steps involved in pursuing a warranty claim are involved and would seem to require keeping all original materials shipped with your battery. Additionally, you'll need a verified reading from an auto parts store to submit with your claim. So, I went to two auto parts stores near my house to test this new battery. Full disclosure, neither store can go below 100CCA with their testers. Arguably, my handheld at home is more accurate. But, as the receipt shows, the battery tested bad 'at the store' too. YMMV, and guessing from the battery mfr code / serial this was likely produced in Oct of 2024, so it may have sat long enough that it's bad from lack of charge (odd, but not impossible). Given the lack of response from Mighty Max (who I trust will respond to this review), and the multiple steps to verify if I received a GOOD battery, I'm recommending that you test your batteries before you install and ride off down the road. I'm within my 30 days to return with Amazon so no headaches on warranty / replacement here. I've also ordered a replacement from a different vendor. I'll be sure to test that battery as well. Takeaways: 1) You get what you pay for 2) Warranty coverage is TBD. Be sure to read the fine print. 3) Invest in a decent battery tester. If you're frugal on your batteries, put that money into your tools. Alternatively, you can test at your local auto parts / moto store. Definitely do that before you ride down the road or trail and get stuck after your 30 day return window closes.

Excelente precio, buen producto
