Nickel -hydride battery charging method.lithium marine batteries price

　　There are various charging methods recommended by the rechargeable battery. Different charging methods have different requirements for the lines of the charger, and naturally affect the cost. The most commonly used simple charging method for nickel -cadmium and nickel -hydride batteries is to use 10%C constant current charging, which is also called "slow charging", that is, the charging current is determined at 10%of the current capacity value. Battery, its recommended charging current is 50mA; as a bid, it is called a battery with a capacity of 1300mAh, and its recommended charging current is 130mA. It can be fully charged for 12-15 hours under this current.

　　Memory effect is a major natural enemy of the rechargeable battery. It is generally considered to be caused by long -term incorrect charging. It can make the battery prematurely. Memory effects can make the battery unable to effectively charge. When it appears, it will be full, and it will be used up as soon as it is used. The method of preventing the memory effect of the battery is to ensure the principle of "sufficient lighting" of the battery, which means that it is best to put the residual power in the battery before charging, and it must be sufficient at one time when charging. Usually nickel -cadmium batteries are prone to memory effects, so special attention should be paid to theoretically when charging, there is no memory effect in theory, but it is best to follow the principle of "sufficient light". This is why many chargers provide discharge additional functions. Essence For batteries that decline in capacity due to memory effects, we can repeat several times through a one -time adequate and one -time light, and most batteries can be repaired. For some long -standing time, batteries that lose activity can try to use large current shocks to try to fight.

　　Although it is recommended to use constant current charging, the requirements are not strict, and the current allows large fluctuations. Therefore, the charger structure made according to this method is very simple. Generally, only one transformer that is converted to 220V is converted into a proper low voltage. Diodes, resistors for current limits, and some light -emitting two -machine pipes are very low cost. Most of the independent conventional chargers on the market use this method, but the appearance is different. "Slow charge" is relatively simple, but it is a bit impatient to wait for more than ten hours to charge for more than ten hours. Battery manufacturers also allow users to charge the battery for 4-5 hours with a current of 30%C in urgent need. It is called "fast charging", but it is not recommended for commonly used. Theoretically, it has slight damage to the battery. Therefore, most conventional chargers have "fast charging" and "slow charging", and it is recommended that users use "slow charging".
