Battery Power Charing Pogo Pin
A rechargeable battery is a rechargeable battery with a limited number of recharges and is used in conjunction with a charger. Generally, No. 5 and No. 7 are sold in the market, but No. 1 is also available. The advantages of rechargeable batteries are economy, environmental protection, sufficient power, suitable for high-power, long-term electrical appliances (such as walkmans, electric toys, etc.). The voltage of rechargeable batteries is lower than that of disposable batteries of the same model. AA batteries (rechargeable size 5) are 1.2 volts, and 9V rechargeable batteries are actually 8.4 volts. Now the general charging times can be about 1000 times. As of February 2012, there are only five types: nickel-cadmium, nickel-hydrogen, lithium-ion, lead storage, and iron lithium.
The battery capacity represents how much power the battery can store, and the number we see on the battery packaging generally refers to the battery capacity mark. It is expressed in units of ampere-hours or milliamp-hours. It is a composite unit consisting of the product of a current unit and a time unit, representing the ability of the battery to continue to discharge under a constant current. A fully charged battery can last for 10 hours with a 200mA current. Multiplying the current and time we can get the capacity of this battery is 2000mA.H. If it is discharged with 400mA, the available time is 5 hours.
