A large number of logistics warehouses, manufacturing factories and distribution centers operating for years have retained a considerable scale of lead-acid legacy electric forklift fleets. For these fleets that have not completed full power source replacement, regular daily maintenance of lead-acid batteries is a core link to ensure stable operation of the whole material handling system. During long-term charge and discharge, distilled water replenishment and routine inspection process of lead-acid batteries, minor acid spillage, local pH value abnormality of electrolyte and other common conditions are hard to completely avoid, which will bring hidden risks of corrosion to forklift components and potential safety hazards to frontline maintenance personnel.

Properly configured battery acid neutralization supplies are low-cost, high-matching supporting solutions for these legacy lead-acid fleets, without requiring any modification of existing forklift battery hardware or large-scale system upgrade. The most commonly used neutralization supplies for daily scenarios are buffered acid neutralization powders with stable chemical properties. Such products will not cause violent exothermic reaction when contacting leaked dilute sulfuric acid on the surface of battery or inside the battery compartment, and can turn acidic liquid into stable non-corrosive solid residues within several minutes, to prevent acid from spreading to adjacent forklift structures or storage facilities.

Another necessary supporting supply is pH detection test strips specially designed for battery maintenance scenarios. After finishing the neutralization operation for spilled acid, maintenance personnel can use the test strips to quickly verify the pH value of the processed contact surface, to confirm all acidic residues are completely removed. This operation can effectively avoid hidden problems such as long-term corrosion of metal battery compartment, accelerated aging of rubber line and adhesion damage of anti-slip floor caused by residual trace acid liquid, reducing unnecessary unplanned downtime of forklifts.

For on-site management, all acid neutralization supplies should be stored in designated ventilated areas near the battery charging station, away from high temperature heat sources, with obvious identification marks for all on-site maintenance personnel to quickly locate. Operation teams should arrange regular check for the validity period of these supplies, and supplement the consumed materials in time to keep the configuration in good standby state. All frontline staff can master the basic operation process through simple routine training, to finish minor acid spill disposal efficiently without starting special-level emergency response procedures.

Reasonable configuration of such targeted acid neutralization supplies can effectively reduce the safety risk of lead-acid battery maintenance for legacy fleets, lower the component loss caused by accidental acid leakage, and help enterprises control the overall operation cost of the existing forklift fleet, which can adapt to almost all daily maintenance demands of common lead-acid electric forklift fleets.
