Recognition with wire short circuitThe two copper core power cords are directly connected to the old battery electrodes to be determined, and then pour normally configured electrolyte (concentrated brine) into a glass cup, insert the two ends of the power cord into the tea cup, and The respective shelves are put on both sides of the glass (two wires can't touch in the cup), then observe the bubbling of the respective leads in the electrolyte, if a certain wire bubble is obvious and more Multiple. Then explain that one end of the power cord connection battery is a negative electrode, and there is a small bubble and the end of the battery is the positive electrode of the battery.
Huizhong - Huizhong brand OPZV tube colloidal battery main components: Polar material 1 # Electrolysis lead, separator is an imported partition for the United States, colloid is German import colloid.
Using rectifier diode determination
The rectifier diode in the power regulator has a unidirectional conductivity to find a rectifier diode. A 40W incandescent lamp. Then press a pilelet → diode + terminal → diode - end → incandescent lamp → the other piode of the battery, and form a motor series, if the incandescent lamp in the circuit is ignited, then proof The diode is extremely connected to the battery pile column is the positive electrode of the battery, and the other end is the negative electrode of the battery.
Nanjing Xiahua battery capacity hourly rate: 1HR, 2HR, 3HR, 5HR, 8HR, 10HR, 20HR, 100HR
The battery used in the general car is a lead-acid battery. Common lead-acid batteries have two types, one is a water-based lead-acid battery, and the other is a maintenance-free lead-acid battery. The battery in which 80% of models in the market is currently maintenance-free lead-acid batteries.
Water-saving lead-acid battery: The polar plate of the ordinary battery is made of the oxide of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantage is that the voltage is stable, the price is cheap; the disadvantage is that the battery is low (that is, the battery stored per kilogram of battery), the service life is short and frequent in daily maintenance.
