Alkaline batteries battery power of carbon sex is 4-5 times the price of carbon, 1.5-2 times. Carbon sex cells for the electric current in low, such as arts, remote control, radios, Alkaline batteries for the electric current in high, such as BP machine, CD, PDA, etc.
The earliest practical battery into the market is xinmeng dry. In 1860, kronor (French) is the Leclanche medias invented the prototype battery acid manganese zinc, the battery is also called Leclanche batteries. It is a negative zinc, battery center is as the anode rod, the graphite conductive materials for graphite anode zone around the bar and carbon powder, powder manganese dioxide anode zone of NH4Cl and to paste ZnCl2 mixture.
Alkaline battery xinmeng in 1950s after entering the market. In recent years, the market in our country, acidic xinmeng batteries are expensive alkaline battery instead of zinc. Alkaline xinmeng battery electrolytes KOH is.
The structure and alkaline battery acid battery completely opposite, battery anode, zinc center is a powder, positive area, is in the outer shell MnO2 and KOH mixture, cylinder is. Alkaline acid manganese zinc overcomes the battery storage battery voltage instability and faults, but still be non-rechargeable batteries.
Both have the same voltage is 1.5 V, but also volume of alkaline battery capacity is bigger, more can adapt high discharge current.

Alkaline batteries, nominal voltage is 1.5 V, its electrolyte is water soluble potassium hydroxide solution, large capacity, can anti-shocking, various aspects are superior properties of manganese dry. In practice, the need to large current circuit, alkaline battery can play a role. Alkaline dry in the use of the tape, heard WALKMAN than common battery life long, the camera in many flash every cell, can use nickel alkaline battery is the best choice. But the alkaline battery price is more expensive.

Most of the alkaline battery chassis, marked “charge” Chinese or English, but in fact, the alkaline batteries can be recharged, can charge a dozen times. Only on the alkaline battery can take small current charge, using the method of charging current 50mA advisable, and most of the charger charging electric current is larger, the battery in liquid flows, corrosion appliances. LR20 LR6 battery, representing one representative 5 alkaline.
