The charging time of lead-acid batteries is closely related to their service life:
If the charging time is too short, it will cause the battery to be undercharged, leading to the sulfidation of the active substances, reducing the battery capacity, and shortening the cycle life.
If the charging time is too long, it will accelerate the aging of the plates, cause water loss in the battery, and even trigger thermal runaway, thus affecting the battery performance and shortening the service life.
An appropriate charging time is crucial. After the battery is completely discharged (100% power consumption), the charging usually takes 8 to 10 hours and should not exceed 12 hours. When the battery has about 70% of its power remaining, the charging time is approximately 6 to 8 hours. After the charger indicator turns green, a floating charge for an additional 0.5 to 1 hour is advisable.

Lead-acid batteries and lithium batteries differ in several aspects. In terms of materials, lead-acid batteries consist of lead, its oxides and sulfuric acid electrolyte, while lithium batteries use lithium metal/alloy as the negative electrode and various materials like lithium cobaltate for the positive electrode with organic or polymer electrolytes. Lithium batteries have higher energy density and charge-discharge efficiency, as well as a longer cycle life compared to lead-acid batteries. Lead-acid batteries are relatively safer but the sulfuric acid in them is corrosive. Lithium batteries have safety risks if misused but safety has improved. Lead-acid batteries are cheaper, and lithium batteries are more expensive but the cost is decreasing. In terms of environmental friendliness, lead-acid batteries contain harmful heavy metals and need proper recycling, while lithium batteries are relatively more eco-friendly but also require reasonable recycling.

YHZC series surge protector (Surge Protective Device, referred to as SPD) is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt in a very short time, thereby preventing the surge from damaging other devices in the circuit. Surges are generated from a wide range of sources, such as lightning induction, switch operation, electrostatic discharge, etc.
