Direct Replacement for Petzl Headlamps
This Cameron Sino battery replaces the Petzl ICR18650-35 cell used in E36NAO, Nao, Nao+, Neo and Stirnlampen models. It delivers 2600mAh at 3.70V with a 9.62Wh energy rating. The lithium polymer pack matches the original dimensions of 68.00 x 18.50 x 18.50mm and weighs 47.0g. A fully decoded chip ensures plug-and-play compatibility without firmware issues.
Stable Output and Built-in Protection
The cell maintains a steady 7.4V nominal voltage during normal headlamp operation. Internal circuitry provides overcharge, over-discharge, over-voltage and short-circuit protection to guard both the battery and the lamp electronics. No cooling fan or active thermal management is required; the polymer chemistry runs cool in typical indoor or outdoor use. The pack is certified to ISO9001, RoHS and CE standards.
Drops into Existing Battery Compartment
The pack fits the original battery cavity without adapters, cables or case modifications. Its 18650-style form factor frees up no additional space but requires no extra clearance beyond the stock dimensions. Installation videos are widely available for reference. Users who need longer runtimes than 2600mAh provides or who operate in extreme temperatures beyond the chemistry's normal range should consider alternative power solutions.

Questions about this item
How do I install the Cameron Sino ICR18650-35 battery into my Petzl Nao+ headlamp, and what is the common mistake?
Align the connector with the headlamp's port and press firmly until it clicks; the step people miss is fully seating the connector so the decoded chip communicates with the device.
What maintenance will this 2600mAh lithium polymer pack need over its life?
Perform 2 or 3 full charge and discharge cycles when new to reach best performance, then avoid low-quality third-party chargers to preserve the protection circuit.
At 3.70V and 9.62Wh, what limit appears first during a long night run with the Petzl Neo?
The 2600mAh capacity sets the runtime ceiling; sustained high output will deplete the 9.62Wh pack before thermal or voltage limits are reached.
