Standard wiring and regular maintenance ensure the stable operation of  lead-acid batteries. Check the positive and negative electrodes during installation and maintenance to avoid reverse connection and circuit damage. Keep wiring terminals clean and tight, regularly remove dust and oxides, and apply a small amount of petrolatum to prevent corrosion and avoid heating and sparking caused by poor contact. Inspect the battery daily for shell damage, liquid leakage, bulging and abnormal electrolyte level. Prohibit overload discharge and short circuit, and avoid severe vibration and impact. Perform balanced charging every three months to balance cell voltage and improve battery performance and stability.
