What is battery capacity testing?

Battery capacity, typically measured in ampere-hours (Ah) or watt-hours (Wh), indicates the amount of energy a battery can store and deliver under specific conditions. Accurate capacity testing ensures that batteries meet their specified performance metrics, helps predict their lifespan, and identifies potential degradation issues.

What is battery capacity?

Understanding Battery Capacity Battery capacity refers to the total amount of electric charge a battery can deliver when discharged from a fully charged state to a specified cutoff voltage under defined conditions. It is influenced by factors such as discharge rate, temperature, and battery age.

How do you measure battery capacity?

Several methods are used to measure battery capacity, each with advantages and limitations depending on the battery type (e.g., Li-ion, NiMH, Lead-Acid) and application. The most common method involves discharging the battery at a constant current until it reaches the cutoff voltage while measuring the total discharge time.

How do you test a lithium ion battery?

Standardize Test Conditions: Follow manufacturer or industry standards (e.g., IEC 61960 for Li-ion). Pre-Condition the Battery: Fully charge and rest the battery before testing. Control Temperature: Test at 25°C unless evaluating thermal effects.
