Tytaneum KTZ10S AGM Battery — replaces YTZ10S

SEALED MAINTENANCE FREE:Once these batteries are put into service, they become a completely sealed unit requiring a lot less maintenance than Conventional Batteries. Although the battery still needs to be charged on a regular basis if your vehicle is not in use, there is no need to monitor the fluid level in this battery type. Unlike the conventional Battery, once this type battery is sealed, it becomes spill proof, which can eliminate damage from battery acid that can occur from using a flooded battery. FACTORY ACTIVATED MAINTENANCE FREE:The same convenience and technology as the Sealed Maintenance Free Batteries, except this battery is sealed and activated at the time of manufacture. Very convenient to the point that all that needs to be done is put the battery into your vehicle and you are ready to ride. The only downside of this type of battery is that all batteries once activated have a shelf life, and if this battery is not going to be used right away, or be put in a vehicle that is not going to be ridden on a regular basis, the battery will need to be kept charged on a batter maintainer.
