Ordinary No. 7 battery does not support charging, only a dedicated rechargeable battery with a special charger can be charged and recycled. Disposable batteries are commonly known as \"disposable\" batteries, because after their power is exhausted, they can not be recharged and can only be discarded.
Common disposable batteries include alkaline manganese batteries, zinc manganese batteries, lithium batteries, silver zinc batteries, zinc empty batteries, zinc mercury batteries and magnesium manganese batteries. Rechargeable batteries according to the production of different materials and processes, common lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-metal hydride batteries, lithium-ion batteries.
The advantage is that the cycle life is long, they can be fully charged and discharged more than 200 times, and the load force of some rechargeable batteries is higher than that of most disposable batteries. In the use of ordinary nickel-cadmium and nickel-metal hydride batteries, the unique memory effect causes inconvenience in use and often leads to premature failure.
No. 7 battery, some can be charged at home, some can not, um, like a lot of the kind of No. 7 battery bought on the market, are not able to be charged, only the No. 7 battery like nickel lithium battery can be charged, because it is that kind of material it can be repeatedly charged, um take into electricity, However, like many No. 7 batteries on the market at present, they can not be used once and can not be recharged.
