Mighty Max BatteryYTX4L-BS - 12 Volt 3 AH, 50 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

I bought the 2 pack. One went into a 2003 Big Bear and the other into a 2005 Polaris sportsman 90. The battery is a little small in size for the the Big Bear but still works perfectly. On the smaller Polaris, it is a perfect fit. Batteries came fully charged, all I did was do them in place. Great value!

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.

Great price works perfect

The screw hole on the positive charge was too small for the screw to fit in. A perfectly annoying problem that no one really wants to spend time fixing, but less hassle than returning it and buying a new one. This was perhaps just a problem on the unit I received, but it was a pain in the neck. Battery works great once installed, no complaints on the power - worked fine out of the box.

Battery shipped fast, packaged well, and was fully charged. Installed on generator and fired right up. So far great little battery for the price.

They worked good for about a week and then one of them went bad already I had to buy different batteries maybe it was just bad luck with one not sure.

These batteries have been great. I've got two now and they are both perfect no issues

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 for2) 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.
