Regardless of any self-discharge characteristics of the battery has, so when the new battery into your hands, which may be rechargeable batteries have been middle of a period of self-discharge of the. This is the rechargeable battery's internal chemical raw materials have gone through a period of time is not used, a "passive" state, unable to give full play to chemical reactions, provide enough voltage. In this case, the first rechargeable battery, be sure to charge the battery is full, so that voltage is restored to its original level. In fact, if you do not use rechargeable batteries for a long time, will produce the same kind of "passive" phenomenon, and the situation is more serious. Preferably 3 to charge the battery charge and discharge process, will help recharge the battery activation. Let the chemicals inside the battery charge can give full play to the desired effect (nickel-cadmium batteries). Sometimes a new purchase, rechargeable batteries into the charger when not fully charged in the charger to stop charging until the. When encountered this problem, you simply remove the rechargeable battery charger, and then put the charger to continue charging. This new rechargeable batteries it is quite normal, not bad you buy rechargeable batteries (nickel hydrogen, lithium-ion battery.) In general the time the charge can not be too long, sufficient for up to 12 hours, if passed, would be to charge the battery over-charging damage.
How to calculate the charge time?
Charging time (hours) = Battery capacity (mAh) / Charging current (mA) * 1.5 of the coefficient
If you use 1600mAh rechargeable battery, charger with a 400mA current charging, the charging time is: 600/400 * 1.5 = 6 hours (Note: This method does not apply to purchase a new or long-term is not used rechargeable batteries)
Ni-MH rechargeable batteries and lithium-ion rechargeable battery is actually a memory effect, using them really do not discharge it?
In fact, the nickel-metal hydride rechargeable batteries and lithium ion rechargeable battery memory effect is very slight, not something that we pay attention to it.
(Note that here, do not use the charger discharge function of Ni-MH rechargeable batteries and lithium ion rechargeable battery discharge action, especially lithium-ion rechargeable battery, because of their material factor, and not allow the battery itself can withstand charger forced discharge. If you insist on lithium-ion rechargeable battery to discharge, will ultimately lead to cell damage.) Also, you need to use nickel-cadmium rechargeable battery discharge, it is recommended that you use the battery regardless of whether the frequent number of times, the most well every two to three months or so on a nickel-cadmium rechargeable battery charge and discharge, ensuring that nickel-cadmium rechargeable battery battery memory effect to minimize the impact on the state.
