Headlamp Batteries: How to Choose the Correct Type

The correct headlamp battery is the one specified for your exact lamp. Check whether it uses standard cells, a dedicated pack or both.

Headlamp batteries are model-specific. Many lamps use AAA cells, while rechargeable designs may use a dedicated pack or built-in battery. Petzl ACTIK CORE is a documented hybrid example: it accepts its CORE pack or three standard batteries. Match format and polarity to the manual; lamps from one brand do not necessarily share batteries.

Common questions

Questions before you buy

How do I find the right batteries for a headlamp?

Read the model label or manual and match the stated cell type, number, polarity and chemistry. Avoid substitutes chosen only because they physically fit.

Can I use rechargeable AAA batteries in a headlamp?

Only if the manufacturer permits the cell chemistry and voltage. Check the manual because operation may differ from alkaline cells.

Do rechargeable headlamps use replaceable batteries?

Some have removable packs, some use built-in batteries, and hybrid models may accept standard cells. Confirm the exact design.

How should I store headlamp batteries?

Follow the battery and lamp instructions. Remove cells for long storage when directed and keep them away from heat, moisture and loose metal objects.
