EarthXETX12A Lithium Battery with BMS. Replaces YTZ7S, YTX7L-BS, YTX7A-BS, YT7B-BS, YTZ5S, YTX4L-BS, YTX5L-BS

Huge upgrade over the stock battery on my motorcycle. Several pounds lighter and more power. It is a healthy premium over the price of the stock battery, but well worth the cost.

This battery is excellent. Extremely light and fits and starts my KTM 300xc perfectly.

The weight in incredibly light and the power has been better than good. I wish it had a little more foam filler to take up space that the original battery did but not a problem. I put this in a Honda 3000IU because the remote I had would not work in the winter or summer with a battery at less than full power. This battery has not failed yet to operate the choke and starter systems when needed. Thanks for the great product.

I bought this battery for my 2006 Kawasaki Ninja 650. It worked great for a few months, and then sat on a tender most of winter. Battery tender came unplugged and battery is now dead dead. They say their battery can go 8+ months without being on a tender, but mine is only 9 months old since purchase. Talked to store on Amazon, they said call EarthX as it’s under warranty for 2 years. EarthX is denying my warranty as they say the battery is too small for the bike.Even so, if it’s off, and can’t hold a charge for a few months, isn’t that a warranty issue?It would be different if I claimed the battery wouldn’t start my bike fast enough, or ever due to only having 135 CCA. When it worked, it worked fine.Bought a different companies replacement. Can’t stand companies that don’t honor their warranties.

Turns my 2012 ktm 300 over great when its good and hot. Bike has a terribly designed starting system so no amount of good battery is gonna start it cold. Overall I'm happy with the battery and proud to support an American company. Keep those shifty Chinese garbage factories out of here.

I have had this battery for 2 years and was just about 10 days past the warranty and they denied the claim. Unfortunately the performance of the battery was deteriorating the second year and I should have sent in a warranty claim then but I forgot it was a 2 year warranty. Mine charges and reads full, but doesn't last more than 3-4 starts before it won't turn the engine fast enough to fire the engine anymore. Charging system good, KTM450, have the cheaper red MMR battery bought same time on my other bike and its still working fine. I thought this would have been the one to last over the Chinese import. Also thought the company wouldn't be such sticklers on the warranty expiration only a week and half back. Only charged with a lithium charger and never jumped its whole life, it just pooped out early and was an expensive experiment.

Much more cranking power than any regular lead acid battery. It really helped to turn over my high compression engine.**UPDATE** 1 year later and I am on my second replacement. Both batteries would not hold a charge anymore just sitting on the bench. I just can't trust them anymore. I really can see how they get 8 years out of them because I haven't been able to get just one. I'm very familiar with LIPO and the special needs of those batteries; my son races RC cars and we have all the special chargers for them and are very knowledgeable, that is why I went with a battery that includes the circuitry required for these batteries. I expected much more life out of this one.I love the lighter weight and the higher current capacity but I really losing my love for it.

Cranks my TE449 over beautifully. Only had it a few weeks but I can notice the difference, especially when the beast gets hot and still cranks right up. Light too.
