1.Insane Performance: Delivers over 350-amps of starting power, over 2000 charge cycles with 100% DOD. 3 to 5 times the energy density of lead-acid. Service life of 5 to 10 years. In contrast, even the best lead-acid battery is typically only good for 300 to 500 cycles. 2.Lightweight :1.63 pounds, one-third the weight of a lead-acid battery, Great for weight savings, especially for racers!It has 2000 charging cycles and a lifespan of 5-10 year. 3.Why Choose Lithium Battery:Low discharge rate，lithium batteries only lose 1-2% of their capacity per month, while lead-acid batteries may lose 30% of their capacity per month. And lithium batteries have a higher resting voltage, which allows you to start your engine quickly and easily. 4.Friendly:Enershare lithium-ion batteries are lead free and acid free, contain no harmful metallurgy and are safer to the rider, installer, vehicle or the environment. 5.Works with most motorcycle brands including BMW, Kawasaki, Harley Davidson, Honda, Suzuki, Yamaha, Aprilla, Buell, Ducati, Triumph, KTM, Argo, Can-Am, Husqvarna, BRP, Waverunner, Polaris, Vespa - motorcycles, ATVs, UTVs, PWCs, quads, 4 wheelers, jet skis, waverunners, scooters, riding lawn mowers. 6.Replaces Battery Sizes: YTX9-BS,GT9B-4,12N7-3A, 12N7-3B, 12N7-3B2, 12N7D-3B, 12N9-3A, 12N9-3B, YB7L-A, YB7L-B, YB7L-B2, YB9L-A2, YB9L-B, 12N7, 12N7-4A, 12N7-4A2, 12N7-4B, YTX7E-BS, YB7-A, YB7-A2, YB7-B2, YB7A-A, YB9-A2, YB9A-A, YB9-B, 12N9-4B-1, YTX9A-BS, HVT-9 7.Warm reminder, if the starter battery cannot start the motorcycle, it is recommended to charge the battery before using it.
