9v Rechargeable NiMH Battery Performance

The only 9v Great Battery Shootout and Showdown. 9v Rechargeable Battery Performance tests reveals the capacity ( also known as mAh ) or energy delivered ( also known as Wh ) of each 9v Rechargeable Battery. ( see FAQs and Glossary for more information. )

Understanding 9v Rechargeable Battery Performance

The column "Actual Capacity (%)" is a calculation of the percentage of the total capacity delivered.

Example : If a battery label says 2000 mAh and the rechargeable battery delivers 1800 mAh, then the battery delivered 90%.

100% is expected. A higher the number means a better battery.
