Forklift battery type

1. Lead acid batteries

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

2. Nickel cadmium batteries

The application of nickel cadmium batteries is second only to lead-acid batteries. Its specific energy can reach 55W · h/kg, and its specific power exceeds 190W/kg. It can charge quickly and has a longer cycle life. It is more than twice that of lead-acid batteries and can reach over 2000 times, but its price is 4-5 times that of lead-acid batteries.

3. Nickel hydrogen batteries

Like nickel cadmium batteries, nickel hydrogen batteries also belong to alkaline batteries, and their characteristics are similar to nickel cadmium batteries. However, nickel hydrogen batteries do not contain cadmium and copper, and there is no problem of heavy metal pollution.

4. Sodium sulfur battery

Sodium sulfur batteries are also the most promising electric vehicle batteries in recent times. Sodium sulfur batteries mainly have the characteristics of high temperature corrosion and short battery life. The performance stability and availability are not ideal.

5. Zinc air battery

The specific potential energy of zinc air batteries is about 200w · h/kg. It still has disadvantages such as short service life, low specific power, inability to output high 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 achieves energy storage through physical methods.

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 is not affected by thermal processes and cycles, therefore its energy conversion efficiency is high.
