Use Battery General Knowledge:

*150% new rechargeable battery first, and then re-use. New batteries are generally three to four times to go through the cycle of charge and discharge capacity to the highest value.

*In principle, be used in the order: full > run > full; (Note that rechargeable batteries can not overcharge and over discharge).

*Keep the battery clean and positive and negative, to ensure the normal use and charging.

*Rechargeable batteries are not afraid to use, but the fear of long-term (one year or longer) is not used. That because of the long-term self-discharge and cause the battery to be placed without electricity, resulting in passivation of the internal material, voltage as low as zero volts and can not restore its original capacity, or even unusable.

*Do not use old and new batteries or put together a different state of charge to use, not to capacity, type and brand used together different types of batteries and charging.
