subject: Nickel-cadmium Batteries Are Generally Discharge Storage [print this page] Taking into account the phone battery indicator error and other factors, when a green light when the charger can charge 1.5 hours more. Another point we should note that lithium batteries will not impose long-term place to sleep, normal use before the need to activate. Usually after 3 to 5 charge and discharge cycles can be activated. Known under the first two reasons, expectations for sleep in the lithium battery to activate through the long charge is meaningless. Because after the battery is full (about 2 ~ 4 hours), has been movement on the lithium battery protection circuit, cutting off the external power supply. As the role of protection circuit, a long time although no damage charge on lithium, but the protection circuit will start the energy consumption of batteries, circuit protection lost if the role can range from damage to the battery, and at the damage the phone, again the idea of the consequences of not . Therefore, taking into account cell phones, lithium batteries and chargers, individual differences, charging three times before and after the charge are the same, only 3 to 4 hours.laptop battery
Nickel-cadmium batteries are generally discharge storage, because it involves issues of dendrite, cell body that is blunt and to the Department may dissolve crystal sharp and cause a short circuit. For NiMH batteries generally charge 40-50% of the power can be, to prevent the reaction of hydrogen and water. But not too filling, to prevent danger.
The following is an excerpt from a company related to storage: Storage
1. Studies show that Ni-MH battery charging state storage better than to keep the battery discharge state storage performance, so best to store the battery before charging the battery.
2. The battery short-term storage of not more than 3 months, the battery can be stored in -20 - +45 , relative humidity 45% - 85% of the place and no corrosion, high temperature easily lead to battery leakage, reduce the battery performance, high humidity could easily cause the battery corrosion of metal parts
Long-term storage battery temperature is best kept at -10 - +30 . Battery after the first use by the long-term storage, the capacity may be lower than the store before, but after several charge and discharge after use, the battery can store before the resumption of the performance. If the battery is stored for more than six months, it is recommended to charge the battery at least six months, up processing Power tools battery
