Mighty Max Battery YTX30L-BS -12 Volt 30 AH, 385 CCA, Rechargeable Maintenance Free SLA AGM High Rate Series Motorcycle Battery

After a long break, I needed a new battery to get my bike project moving forward again. Bought this Mighty Max battery and was glad to see it was nearly 13V right from the box. Fit was good in the bike, and b/c the carbs were all empty it took a while to get it turned over, but the battery never gave up. I cranked on it off and on for a while and it never got too low. Always rebounded great from key on to key off. Finally the gas got moving and it turned right over. Idled for a while, and now I have plastic to put on. Do like me: overcome your laziness and get things ready to ride again. Getting a new battery really got this project to the finish line and got me in the mood to get riding again! Two bikes down with new Mighty Max batteries, two more to go!

Battery is as described and arrived fully charged. Worked on my 2022 Canam Spyder F3 LTD for a third the price of the dealers battery. Amazon said it wouldn’t fit but I bought it anyway based on the group number and measurements. It Is identical to the original battery in size, cca and terminal placement.

Battery seems good. The grizzly 660 2003 started right up didn’t have to charge the battery. The only downfall is like customers are saying is the battery connection it’s terrible but the best way to give you is they have these little flat nuts with rectangular connectors, so my best advice would give you is use electrical tape shovel electrical tape underneath the first put the bolts to hold the flat nut into the square box on the plus and positive and minus side then installed Electrical tape to keep the nuts in place because the batteries fit lay down inside the belly of the grizzly and then put electrical tape around the hole connector and everything worked out fine

I only deducted 1 star because the battery is new and it's not really fair to give 5 stars before seeing how long it lasts. Otherwise the battery fits and the bike started up much stronger than with my failing old battery. It was easy to install with the provided bolts and we'll see how long it lasts. Overall the price made it an extremely good value

I've been running this Mighty Max battery for a full year now and it has been great. I can't remember exactly which bike I put it in—I have a few dirt toys—but it has worked every time I hit the starter. For the price, you really can't beat the value and reliability. It's a solid, maintenance-free option that just works.

Free overnight delivery! And it came fully charged. Had to bend and shape my battery cable ends because these battery posts are slightly different but no big deal. Atv fired right up. A local battery was 2x what I paid for this one.

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!

Going on 3 years with this battery. Doesn't hold a full charge without being used for a few days.

Su capacidad y función no le pide nada a las más caras

Ordered for my quad didn’t fit, but to my surprise it was the perfect replacement battery for my sled. (Yamaha RS Venture)

Very happy

Didnt even make it 1 year and now wont hold a charge for more than a few hours

Works great, got it for my 2007 Vulcan 900. I keep.the battery charger on it though. But I have no complaints.
