In the field of logistics warehousing, production and manufacturing, forklift is an indispensable "handling expert", and lead-acid battery as its core power source, directly determines the work efficiency and operating costs of equipment. Although the lead-acid battery equipped with HYSTER forklift truck is known for its durability, if it lacks scientific maintenance, it may still "die" in advance due to problems such as vulcanization and plate corrosion. This article will start from the actual application scenario, reveal the five core skills to extend battery life, to help you achieve "one battery for ten years" efficient operation and maintenance.

First, charging habits: Avoid the two "invisible killers"

More than 70% of the life loss of lead-acid batteries is due to improper charging. Here are two details to focus on:

1.Put an end to the "use with charge" misunderstanding

Frequent shallow charging will cause the electrolyte to delaminate and accelerate plate sulfate crystallization (vulcanization). It is recommended to start charging when the remaining battery power is 20%-30%. After charging to 100%, leave it for 30 minutes before using it to ensure that the electrolyte is fully balanced.

2.Avoid the "hot charge" trap

The battery temperature should be controlled below 35 ° C during charging. If the ambient temperature exceeds 30 ° C, it is recommended to use the two-stage charging mode: first charge the battery with the standard current to 80%, and then switch to the trickle mode to complete the remaining 20% to prevent the battery from overheating and bulging.

Second, daily maintenance: The "golden rule" of electrolyte management

The electrolyte status is a "barometer" of battery health, which should be checked weekly and followed the "three control principle" :

◆Control level: The liquid level should always be 1-2cm higher than the plate, and add distilled water (not ordinary water) to the specified scale to prevent the plate from being exposed to oxidation.

◆ Specific gravity control: The use of hydrometer detection, single cell battery electrolyte specific gravity deviation does not exceed 0.025. The standard value after charging is 1.28±0.01 (25℃ environment), if it continues to be low, vulcanization or short circuit should be checked.

◆Purity control: It is strictly prohibited to mix impurities, and after adding liquid, it is necessary to stand for 2 hours before charging to avoid the electrolyte boiling overflow.

Third, environmental optimization: temperature and cleaning "double insurance"

The impact of the external environment on battery life is often underestimated, and the following measures are recommended:

◆Temperature control: The best working temperature is 20-25℃. When it is lower than -10℃ in winter, the battery should be preheated to more than 5℃ before charging; During high temperature periods in summer, you can install thermal insulation cotton or cooling fans in the battery compartment.

◆Clean and leakproof: Clean the battery surface and terminals with 5% baking soda solution every month to prevent acid crystallization resulting in leakage. Apply special anti-corrosion grease to the pole to reduce contact resistance.

Fourth, the use of specifications: the operation of the "energy-saving secrets"

Improper operation will accelerate battery overdraft, you need to cultivate the following habits:

◆Slow start slow stop: Avoid rapid acceleration or sudden braking, instant large current discharge will shorten the life of the plate.

◆Load adaptation: the load should not exceed 80% of the specified capacity, and the low-speed gear should be used preferentially during slope operation.

◆Power off protection: Stop for more than 15 minutes must close the electric lock to prevent the controller standby power consumption.

Fifth, deep maintenance: dormant period and vulcanization repair

For batteries that are out of service for a long time or have reduced performance, advanced maintenance measures can be taken:

◆Sleep maintenance: Charge to 50%-70% before storage, recharge once every 3 months, keep the storage environment dry and the temperature is not lower than -15℃.

◆Vulcanization repair: For batteries with capacity attenuation of more than 30%, the use of pulse repair instrument for devulcanization treatment (voltage set 12V, frequency 1kHz, lasting 8-12 hours) can recover about 60% of the capacity loss.

Conclusion

The design life of the lead-acid battery of HYSTER forklift truck is usually 5-8 years, but through the above systematic maintenance, the actual case has achieved 12 years of ultra-long use record. The key to battery longevity is to "prevent the micro gradually" - from every charge, every drop of electrolyte, every standard operation, in order to maximize the return on investment. Remember: the savings are not only the battery cost, but also the hidden loss caused by downtime!
