Electric Pallet Jack Company Introduces Battery Maintenance for Electric Pallet Jacks

As an important accessory for power, the importance of the battery is self-evident. The common sense of electric pallet truck battery maintenance is as follows:

1. Preparation before use

1. Lean forward to read the manual in detail, keep the battery away from flames, sparks, and cigarette butts, and keep it ventilated after charging. The battery may explode if misused.

2. Pay attention to personal protection when working next to the battery while charging the battery. The battery contains sulfuric acid liquid. Avoid contact with skin, eyes, and clothes. Once in contact, rinse with plenty of water immediately.

2. Battery maintenance and precautions

1. Check the liquid level every other week. If it drops, please refill it with distilled or purified water. The surface of the battery, connecting wires and bolts should always be kept clean and dry. If there is acid, it should be wiped off with cotton gauze dipped in alkali solution, then rinsed with clean water and dried. During cleaning, do not allow alkaline solution to enter the battery.

2. The connection of the battery must be kept in good contact, so as not to cause sparks to cause the battery to explode or the pole to burn out.

3. The battery should avoid over-discharging, strong charging and insufficient charging. Failure to do so will shorten battery life.

4. Do not allow any harmful impurities to fall into the battery. The instruments and utensils used to measure the concentration density, temperature and liquid level of the electrolyte should be kept clean to avoid bringing impurities into the battery.

5. Do not place any conductive items on the battery cover, so as not to cause an external short circuit of the battery.

6. After the battery is discharged, it should be charged in time. Long intervals must not exceed 24 hours.

7. If the battery is lagging behind during use, the cause should be found out and repaired immediately. If it cannot be repaired, the battery needs to be replaced.

8. The temperature of the sulfuric acid solution injected into the battery should be between 10 degrees Celsius and 40 degrees Celsius. Do it again.

9. Fireworks are strictly prohibited in the charging room to avoid hydrogen explosion accidents. There should be good ventilation facilities in the charging room, and the temperature must not be lower than 15 degrees Celsius.

10. During the use of the battery, there will often be unbalanced voltage, density and capacity. In addition to preventing the occurrence of the above phenomena, balanced charging can also prevent the occurrence of backward batteries, so that each battery can achieve a balanced and consistent state during use. If one of the following situations occurs, equalization charging should be carried out: a. The discharge voltage often drops below the cut-off voltage; b. When the discharge current value is often too large; c. The charging is not carried out in time after discharge; d. When there are large impurities; e, when it is often insufficiently charged or has not been used for a long time; f, after taking out the electrode group to check or remove the sediment.

Balanced charging method: first charge the battery normally, and wait for one hour after the charging is completed. Then charge with the current value of the second stage of normal charging until violent bubbles are generated, temporarily stop charging for one hour, and repeat this several times until the voltage and density remain unchanged, and then recharge after an interval, and violent bubbles will be generated immediately.

During equalization charging, the voltage, density and electrolyte temperature of each battery should be measured and recorded; before charging is completed, the density and liquid level of the electrolyte should be adjusted to meet the requirements.
