Model D is AA battery, widely used, D type batteries can be found in civilian DC power supplies , military and special. The height of the standard D cell (flat head) is 59.0 ± 0.5 mm. diameter 32.3 ± 0.2 mm.
Model
The SC model is not common. This is usually the battery cell in the battery. It is mainly seen on imported power tools, cameras and equipment. Battery (flat head). Height 42.0 ± 0.5 mm, diameter 22.1 ± 0.2mm.
Model C is the AA battery, which has many uses. The standard C (flat head) battery has a height of 49.5 ± 0.5 mm and a diameter of 25.3 ± 0.2 mm.
Model N is uncommon and has fewer uses. The standard N (flat head) battery has a height of 28.5 ± 0.5 mm and a diameter of 11.7 ± 0.2 mm.
F-type batteries, electric mopeds and new generation of power batteries tend to replace maintenance-free lead-acid batteries and are generally used as battery cores. The standard F (flat head) battery has a height of 89.0 ± 0.5 mm and a diameter of 32.3 ± 0.2 mm.

Normal charging
Different batteries have their own characteristics and users should charge according to the manufacturer's instructions. In sleep mode, the phone also consumes battery. If you want to charge quickly, youPlease turn off the phone first or remove the battery to charge it.
Fast charging
Some automated smart fast chargers only indicate that the battery is 90% full when the signal light changes, and the charger automatically switches to slow charging to fully charge the battery full. It is best for users to fully charge the battery before use, otherwise the use time will be shortened.
Memory effect
If the battery is a nickel-cadmium battery, if it is not fully charged and discharged for a long time, it will leave traces in the battery and reduce battery. ability. This phenomenon is called battery memory effect.
Clear memory
The method involves completely discharging the battery and then recharging it. For discharge, you can use a charger or a charger with a discharge function, or you can use thee mobile phone standby mode. If you want to speed up the discharge, you can turn on the lights on the phone's display screen and buttons. To ensure that the battery can be recharged, follow the instructions in the instruction manual to check the time and repeat charging and discharging two to three times.
Battery storage
Lithium batteries can be stored in a clean, dry, ventilated room with an ambient temperature of -5°C to 35°C and relative humidity not not exceeding 75%. They should be avoided. In contact with corrosive substances, keep away from fire and heat sources. The battery power remains between 30 and 50% of the nominal capacity. It is recommended to recharge stored batteries every 6 months.
