Glossary: Battery Aging

Battery aging is the gradual decline in battery performance over time due to chemical and mechanical changes within the cells.

Expanded Explanation

Aging occurs even when a battery is not actively used and is influenced by factors such as temperature, charge level during storage, and usage patterns. As batteries age, capacity decreases and internal resistance increases, reducing runtime and efficiency.

Why it matters

Understanding aging behavior helps design systems that maintain reliable performance over the product’s intended lifespan.

iTECH Context

iTECH accounts for battery aging when specifying cells and system architectures for long-term reliability.

Applications

Medical devices, industrial equipment, long-service products
