Head Torch Rechargeable Batteries: Choose Compatible Spares

Head torch rechargeable batteries must match the lamp's instructions. Start with the model reference and approved battery type, then check how the replacement will be charged.

Buy head torch rechargeable batteries by compatibility, not by appearance. Write down the lamp's full model and generation, then find the battery references and chemistries allowed in its instructions. A similar-sized cell may have a different electrical specification or charging requirement.

Common questions

Questions before you buy

Can I put any rechargeable AAA batteries in my head torch?

Only if the instructions allow that chemistry and format. Confirm the permitted types for the exact lamp and use a suitable external charger where required.

Is a Petzl CORE battery universal?

No. Petzl specifies compatibility with its HYBRID CONCEPT models; other Petzl lamps can use different packs.

Does an adapter make any smaller cell compatible?

No. Use only the combinations the manufacturer approves. Fenix's specified HM70R alternative includes a named holder; it is not permission to adapt unrelated cells.

What information should I give support when finding a spare?

Provide the full lamp name, reference and generation, plus the battery code printed on the existing pack if readable. That is more useful than a photograph of a similar-looking replacement.
