The self-discharge, also known as charge retention capacity, that means when it is in open circuit state, the maintain ability of battery's storage electricity under certain environmental conditions .During storage time, the rate of capacity loss is called self-discharge rate.It is mainly affected by the manufacture technology, materials, storage conditions and other factors, which is an important parameter to measure the lead acid battery's performance.

The storage capability is an important parameter for checking the stability of general capability. After a certain period storage, the variety of capacity and inner resistance is allowed.And the storage can level off the electrochemistry performance of inner component, so that we can know the extent of self-discharge capability, then pick out the deep cycle batteries with short circuit (caused by fast droping of OCV) and micro short circuit, so the battery quality can be ensured.

The life of batteries always depends on how you use it. In fact, how long and often the motorcycle batteries are charged is also very important, which affect the length of time the battery will last. If you leave the battery unused for long several months, you don't expect the battery to work smoothly when you use it again. And this is why charging the battery correctly is very important. You will find how long you have to charge your motorcycle batteries according to the instruction manuals. Plus, you should always keep it fully charge, even if you're not using it. If your battery is completely exhausted, it will be harmful for your battery. Fully charged battery means it is in good condition. Never charge your motorcycle battery with a car battery charger, because it will damage the battery.
