Mighty Max Battery YTX24HL-BS -12 Volt 21 AH, 350 CCA, Rechargeable Maintenance Free SLA AGM Motorcycle Battery

I use these batteries for starting in a stand-by generator (they have good CCA for their size). They work great and hold charge well for a long time. They can be mounted upside down, on their side etc and they are completely sealed (thus no gassing). They are absorbed glass mat (AGM) sealed lead acid (SLA) batteries. They are NOT gel batteries. They might slosh around a little tiny bit because of they contain just enough of the electrolyte to keep the glass mat wet but meh, that's fine, mine don't slosh at all except in extreme temperatures. True Gel batteries tend to be a bit prema-donna sometimes so I've found over time, these batteries do just fine and will work with any god awful charger.Pro-tip: I replaced my Mighty Max battery in my generator after 5 years when I thought it was dead because the battery tender wouldn't charge it anymore. Come to find out, it wasn't the battery, it was the tender. The original battery is still just fine after 5 years! Always check the tender before relying on it to make a decision on a battery. I should have known better and got lazy. That said, I just put the new one in the generator and kept the 5 year old one around to use for different projects until it finally gives up the ghost. If I get 5 years out of each of these on average I'll be doing just fine!

Amazon states that this works in a 2015 E350 Mercedes-Benz. I cannot recommend that you purchase this for it. I did manage to make it work,, the battery terminals are reversed from factory's, cables barely reached.If you think about how much cheaper it was then the other batteries if I get length of time out of it it was a darn good deal.And I was able to use this battery to make sure that yes I need the battery...Just if you ain't talented and mechanically inclined don't try to put this in a Mercedes-Benz E350 2015..

This fit my 93 250 Timberwolf perfectly with some adjustments to the battery compartment spacers/padding. After first running it down with a bad starter, I gave it a full charge on 2 amps/trickle. Replaced the starter, and this battery fired my 250 right up.6 (which had sat idle, without use for nearly 2 years). She fires up Every time! Single digit temps, no problem! This is a keeper and one that will get the battery tender when not in use. Impressive little battery for the cost. Sealed, no need to add acid, no maintenance, perfect! Great deal for this one fme.

I needed a replacement battery for my V Star 1300. This was $55 compared to $120 and up elsewhere. I don't need whatever new tech they're selling and it turned out Amazon was the only place for a more conventional lead acid battery. It fit in the bike's battery box and arrived charged. So, all great news - except: the battery posts are difficult to hook up. My last posts were free standing with some space on each side. These were up against the top of the battery with no space for the lip of the lead to fit behind the post. I had to bend the lip to make contact. My other issue was the provided nuts and bolts. My last posts were threaded so connecting the lead was easy as I just had to line up the holes and put in the screw. With the new battery, I had to line up the lead with the special nut that slides into the post. I got it connected - after dropping the nut (both of 'em) in the bike and finding them again. So, working battery at a good price - but the hook up should have been easier.

Worked perfect for my CanAm Spyder and fit like a jem. Warranty is solid and way better than I could find local. While the shipping box was crushed it appears to have not impacted the battery.

Fast shipping at a great price.

Battery came fully charged at 13.1V and works very well. Holds a charge, and I have even let it drain down due to voltage draw issues on my bike. The battery charges right back up to 13 volts and maintains its charge even after the multiple drains I have done since purchase.

I bought this battery on November 7th, 2023, for my 2005 Polaris Ranger 700 XP 4x4. I don't drive the vehicle every day, or even every week, but every time I turn the key it starts right up. The only reason I didn't give 5 stars is because the last big snowstorm we had (January, 2025) the battery was too low to actually start the engine. It still was able to run lights, etc., and after a quick jump it started with no issue. I have had no issues before, or since. In fairness to the battery, the temperature was single-digit fahrenheit and the vehicle had been sitting for over a month.A decent battery for the price I paid. Cannot complain.
