Abnormal changes in the voltage of the CR2032 button cell battery

　　The battery is composed of multiple cells connected in series. Battery 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. Maintenance of traction battery terminals, wires, and covers must be carried out by professional technicians designated by the manufacturer. Operations other than inspection of electric forklift batteries: Professionals should be consulted, especially when replenishing electrolyte (dilute sulfuric acid). For example, pallet stacking forklifts are 24V, storage and handling electric forklifts are 48V, electric golf carts are 72V, and electric tractors are 80V. Through the analysis of sales data in recent years, it was found that many customers did not use forklift batteries under the specified electrical parameters, leaving the forklift batteries in abnormal states such as overcharge and overcharge. The main reasons are: insufficient maintenance, inaccurate instruments, and inability to adjust the working voltage in time as the environment changes. The working voltage of the CR2032 button cell battery has a great impact on the life and capacity of the battery pack.

　　The battery life of an electric forklift is affected by the float charging voltage. When the float voltage is 2.23 V, the battery life reaches 100%. When the voltage increases to 2.30 V, the battery life is reduced to 75%. Inaccurate instrument measurements also have a great impact on the battery pack of an electric forklift. For example, a customer's electric forklift has 36 battery packs. According to the manufacturer's instructions, the float charge voltage is 2.13 ± 0.01 V. The forklift battery pack floats The charging voltage is 75.9 ~ 77.3 V, the cell density is 1.28 ± 0.005 g/ml (30 ° C), and the DC panel voltmeter shows 75.6 V. However, when testing the CR2032 button cell battery, it was found that the working voltage of most batteries It is 2.03 ~ 2.10 V. The actual output voltage of the charger measured by the voltmeter is only 73.8 V. It is known that the battery has been put into use for 3 years and the working voltage has not been adjusted, resulting in long-term undercharging of the battery and affecting the service life of the forklift battery.
