The parameters that mention above are required to be regular using. If you not use it for a long time , then cyclic number will reveal decrease. And battery life itself, not only concern with the battery charger about, still with electrical equipment. Stable discharging equipment related than pulse discharge equipment battery life is a bit long. Small discharge current equipment is not suitable for use rechargeable batteries.How to judge the battery chagers can recharge or not?Generally speaking, the standard using life of the high quality excellent nimh battery chargers is 300-500 times, Others that have maintenance function senior intelligence charger can achieve 1000 times. Lithium ion battery is about 300-500 times.The parameters that mention above are required to be regular using. If you not use it for a long time , then cyclic number will reveal decrease. And battery life itself, not only concern with the battery charger about, still with electrical equipment. Stable discharging equipment related than pulse discharge equipment battery life is a bit long. Small discharge current equipment is not suitable for use rechargeable batteries.
Nimh battery chagers has certain memory effects, if discharge equipment discharge deadline set to high voltage, the influence of life it, too.Now there are some nickel metal hydride rechargeable batteries in order to improve the capacity, in adding unstable electrode material, can make the cycling times greatly decreased.So to buy suitable charger, for specific equipment fixed use a set of battery to the life of the battery, general AA battery to reach 100 times cycle life also is pretty good.
