How do you test a lead-acid battery?
Lead-acid batteries are highly sensitive to temperature. Testing should ideally be conducted at room temperature to ensure accurate results. Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
What is a lead-acid battery?
Lead-acid batteries are a type of rechargeable battery that uses lead and lead oxide electrodes submerged in an electrolyte solution of sulfuric acid and water. They are commonly used in vehicles, backup power supplies, and other applications that require a reliable and long-lasting source of energy.
