Battery is a device that converts chemical energy directly into electrical energy, designed by the rechargeable batteries, rechargeable by reversible chemical reactions.It’s usually referred to the lead-acid battery, which is one of the battery, belongs to the secondary battery.The working principle is: when charging, use the external electric energy to regenerate the internal active material, store the electric energy as chemical energy, and convert the chemical energy into electrical energy output again when discharging, such as the cell phone battery commonly used in life.

3, In the use and maintenance of batteries need to pay attention to some problems

(1) Battery not being used for a long time, it will slowly self-discharge, until scrapped.Therefore, the car should be started every once in a while to charge the battery.Another way is to remove the two electrodes from the battery.It should be noted that the positive and negative electrode lines should be removed from the electrode column, and the negative electrode line should be removed first, or the connection between the negative electrode and the chassis of the car should be removed.Then pull out the other end with a positive sign (+), the battery has a certain service life, to a certain period of time it should be replaced.

During replacement should follow the same order, when putting electrode line on nevertheless, order is opposite, connect positive pole first, connect negative pole again next.

(2) when the ammeter pointer display storage capacity is insufficient, charge in time.Battery storage capacity can be reflected in the dashboard.Sometimes found that power is not enough in the way, the engine stalled again won't start, as a temporary measure, can seek help from other vehicles, vehicle battery with them to launch vehicle, connected the two battery anode and the cathode, the anode and the anode is connected.

The battery charging time should be determined according to the battery capacity and charging current. 12V batteries can be charged from 1AH to 200AH. Generally, the charging time is no less than 24 hours, large current charging is faster of course.However, many devices charge the battery with constant current in the first stage and constant pressure in the second stage, so as to achieve the longest battery life. If you only use a large battery, the battery charging time is short, but has an impact on the battery life and capacity.
