Ni-MH battery pack - Maintenance Tips and Common Problems

The Ni-MH battery pack is one of the driving devices of the forklift and is responsible for providing power to the vehicle. With proper maintenance, the Ni-MH battery pack can be used for a long time, but if regular maintenance is ignored, it may cause safety problems. This article will introduce the maintenance tips and common problems of forklift batteries to help you maintain the stability and safety of your forklift.

Ni-MH battery pack Maintenance Tips

Here are some maintenance tips for forklift batteries to ensure their long-term operation:

Check the electrolyte level regularly

Checking the electrolyte level is one of the important steps to keep the Ni-MH battery pack in good working order. When using the forklift, the electrolyte level may be too low due to vibration and other reasons, so we need to check regularly whether the electrolyte level has reached the standard position.

Cleaning the battery terminals

Cleaning the battery terminals helps improve the performance and life of the Ni-MH battery pack. Substances such as carbonates or rust present on the battery terminals will gradually form a thick layer over a long period of time, covering the metal terminals of the battery, which will cause insufficient power to the battery and affect the normal operation of the forklift. Therefore, regular cleaning of the battery terminals is essential to keep the Ni-MH battery pack in good working order.

Checking the battery density

While checking the battery fluid level regularly, we also need to measure the density of the battery fluid. Because the concentration and solubility of the battery fluid inside the battery will affect the charge and discharge of the battery, we need to check the battery fluid concentration. If it is below the standard, it can be supplemented by adding electrolyte to ensure the normal operation of the battery.

Charging forklift batteries

Before charging the Ni-MH battery pack, you need to ensure that the positive and negative terminals are clean and free of dirt, and avoid overcharging the battery at the specified current. If there is no special equipment, you can control the charging battery by changing the current of the charger. You need to select the appropriate charging current and time according to the type of battery charging to increase the service life of the battery and not affect the normal use of the forklift.

Common problems with forklift batteries

The following are common problems with forklift batteries:

Low electrolyte level

If the electrolyte level is too low, the battery will not be able to provide enough power for the forklift, which will affect the performance and work efficiency of the forklift. If you find that the electrolyte is too low, you should add an appropriate amount of water in time. However, before filling the water, you need to refer to the level gauge to strictly fill the water.

Failed battery terminals

If the battery terminals do not provide a good electrical connection, the battery will not be able to adequately power the forklift. Usually, the cause is excessive dirt or oxide on the battery terminals, but replacing the battery terminals may cost extra, so you can try a simple cleaning before repairing.

Battery charging problems

If the battery is not fully charged, it will run out of power, resulting in poor efficiency and even the forklift may stop operating. Usually, the reason is that the battery charger does not provide enough charging current or the charging time is insufficient. At this time, the battery needs to be recharged or replaced to achieve a full charge state.

FAQ What causes forklift batteries to be undercharged?

There are usually two reasons for undercharging forklift batteries: not providing enough charging current or insufficient charging multiples. The solution is to use the right amount of battery chargers to maintain a good battery charge state.

Can forklift batteries be charged in a short time?

This depends on the power rating of the battery charger, the charging multiple, the size of the battery, and the health of the battery. But in any case, improper charging can cause damage to the battery, so it is recommended to follow the instructions of the battery charger to ensure that the battery charge state can be guaranteed for a long time.

When does a Ni-MH battery pack need to be replaced?

Forklift batteries usually need to be calculated according to the service period recommended by the manufacturer. The number of bodies that are relatively simple to update the battery will change. The use of the battery can also be determined according to the frequency of use and the charging cycle. Specifically, we need to pay attention to the actual working and charging conditions of the battery. If the battery is aging or cannot be solved by regular maintenance, then updating the battery is the only solution.

Conclusion

The Ni-MH battery pack is one of the core components of the forklift operation. Its maintenance and use are the key to ensure the long-term stability and damage resistance of the forklift. As mentioned above, checking the battery level and density, cleaning the battery terminals, and charging the battery are all important aspects of battery maintenance, which can ensure that the battery is always in good working condition. If the battery is aging or cannot be solved by regular maintenance, then updating the battery is the only solution to ensure that the forklift can operate safely with the correct power output.
