Primary battery, voltage:1.5v.
Zinc-manganese battery, commonly known as carbon battery, is a common dry battery in daily life, with low battery capacity and easy leakage. Commonly used in TV remote control and other products, common products: 1, 2, 5, 7, button type, etc.
2. Alkaline batteries
Primary battery, voltage:1.5v.
The advantage of alkaline batteries lies in their strong endurance, which can be 7 times that of carbon batteries. The current output is stable and there is no leakage. It can be used in instruments and equipment with high power consumption. Common products: 1, 2, 5, 7, button type, etc.
3. Nickel-cadmium battery
Rechargeable battery, voltage:1.2v.
Disadvantages of Ni-Cd battery: large volume, heavy weight, small capacity, self-discharge, memory effect and no environmental protection. Advantages: it can be charged for more than 500 times, and it is resistant to overcharge and overdischarge, and it is simple to use and operate. The internal resistance is small, and it can discharge with large current, so this product is often used for the reuse of electric tools. Common products: 1 (D type), 2 (C type), 5 (AA type), 7 (AAA type), button type and various non-standard models.
4. Ni-MH battery
Rechargeable battery, voltage:1.2v.
The disadvantage of Ni-MH battery compared with Ni-Cd battery is that it cannot discharge at high current (at present, there are factories that produce Ni-MH batteries with high current discharge). The advantages are that the same volume capacity is more than twice as high as that of nickel and cadmium, the memory effect is small, and there is no pollution, so it is called green battery. Common products: 1 (D type), 2 (C type), 5 (AA type), 7 (AAA type), button type and various non-standard models.
5. Lithium-ion battery
Voltage: 3.7V
Lithium-ion battery case has steel case and aluminum case, and the capacity of aluminum case is higher than that of steel case 10%- 15%. Advantages: small size, large capacity and high voltage. The shapes are cylindrical, square and irregular. Commonly used in mobile phone batteries, PDA batteries, notebook batteries.
6. Lithium polymer battery
Voltage: 3.7V
Comparison between lithium polymer battery and lithium ion battery: the outer packaging is aluminum-plastic packaging, which is different from the metal shell of lithium ion. Due to the use of soft packaging technology, thinner batteries can be produced. The shape can be changed at will. Light weight, high capacity, small internal resistance, supporting large current discharge. Commonly used in high-end mobile phone batteries, notebook batteries, various power tools and model batteries.
