It only takes a dozen or so uses before rechargeable batteries make more economic sense than disposable batteries. We test and review the latest models to help you find the best rechargeable batteries. How we test batteries explains our testing rigour.

Our expert testers give every battery a thorough work out to find which batteries:

  • last the longest
  • can be recharged most often
  • lose the least amount of charge when not in use
  • perform at their best for the life of the battery.

Our Recommended list will help you see quickly which models come out on top.

Consistency score

Expand to view more details.

How well a battery retains its initial capacity. For example, a 2500mAh battery should still have close to that capacity after 200 recharges. A low score means the battery loses a lot of capacity over multiple recharges.
