CR1220 battery

　　What types of CR1220 battery are there and what should I pay attention to when charging them?

　　The types of CR1220 battery can be divided into: flywheel batteries, zinc-air batteries, nickel-metal hydride batteries, nickel-cadmium batteries and lead-acid batteries. In addition, you should pay attention to things when charging. For example, when adding water, add distilled water to the liquid surface. Too much electrolyte will overflow and cause leakage. The relevant content will be introduced in detail below.

　　1. Types of CR1220 battery

　　1. Lead-acid battery

　　Lead-acid batteries have a history of more than 100 years and are widely used as the starting power source for internal combustion engine vehicles.

　　2. Nickel-cadmium battery

　　Nickel-cadmium batteries are second only to lead-acid batteries in their wide application. Their specific energy can reach 55W·h/kg, and their specific power exceeds 190W/kg. They can be charged quickly and have a long cycle life, which is more than twice that of lead-acid batteries. It can reach more than 2,000 times, but the price is 4-5 times that of lead-acid batteries.

　　3. Nickel metal hydride battery

　　Nickel-metal hydride batteries, like nickel-cadmium batteries, are alkaline batteries. Their characteristics are similar to nickel-cadmium batteries. However, nickel-metal hydride batteries do not contain cadmium and copper, and there is no heavy metal pollution problem.

　　4. Sodium-sulfur battery

　　Sodium-sulfur batteries are also generally promising electric vehicle batteries in the near future. Sodium-sulfur batteries mainly suffer from serious corrosion at high temperatures and short battery life. Problems such as performance stability and unsatisfactory use safety.

　　5. Zinc air battery

　　The potential specific energy of zinc-air batteries is around 200w·h/kg. It still has shortcomings such as short life, low specific power, inability to output large current, and difficulty in charging.

　　6. Flywheel battery

　　Flywheel battery is a new concept battery proposed in the 1990s. It breaks through the limitations of chemical batteries and uses physical methods to achieve energy storage.

　　7. Fuel cell

　　A fuel cell is a power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy through electrode reactions. It does not undergo a heat engine process and is not limited by thermodynamic cycles, so its energy conversion efficiency is high.

　　2. Forklift battery charging precautions

　　1. Add water

　　Add distilled water according to the specified liquid level. Do not add too much distilled water to extend the interval between adding water. Adding too much water will cause the electrolyte to overflow and cause leakage.

　　2. Charging

　　The battery will produce gas during the charging process. The charging place should be well ventilated and there should be no open flames around. At the same time, the oxygen and acidic gas generated during the charging process will have an impact on the surrounding area. Unplugging the charging plug during charging will cause arcing. Turn off the charger before unplugging the plug. After charging, a lot of hydrogen gas will remain around the battery. No open flame is allowed. The cover on the battery should be opened for charging.

　　3. Maintenance of terminals, wires and covers

　　It must be carried out by professional technicians designated by the manufacturer.

　　4. Cleaning

　　If it is not too dirty, you can wipe it clean with a damp cloth. If it is very dirty, remove the battery from the car, wash it with water and let it dry naturally.
