Product State During Test	Powered off (shutdown)
Measured Parameter	Static leakage current (μA)

Test Procedure

Pre-test: Confirm the product is fully assembled and that the battery is installed. Record ambient temperature (23 °C) and humidity (60 %) in the test log.
Setup: Set the multimeter to the micro-ampere (μA) current measurement range.
Power off: Switch the CL3 unit to the off (shutdown) state.
Measurement: Connect the multimeter in series with the battery circuit and record the static leakage current reading for each sample.
Post-test: Disconnect the multimeter, return the unit to its normal condition, and record all readings in the data table.
Acceptance Criterion: No formal pass/fail limit is defined for this test; results are recorded for reference only.

Test Data & Results

Sample No.	State	Current (μA)
1#	Powered Off	1.4
2#	Powered Off	1.6

Observations: Both samples exhibited very low static leakage current in the powered-off state. The readings of 1.4 μA and 1.6 μA indicate that the CL3’s battery protection circuit draws negligible quiescent current, which is consistent with good standby power management for a battery-operated camping lantern. No anomalies were observed during measurement.

Frequently Asked Questions

What is static leakage current and why does it matter for a camping lantern?

Static leakage current is the tiny amount of current a battery-powered device draws from its battery even when switched off. For a camping lantern like the CL3, keeping this value low — in the single-digit microamp range — means the battery loses virtually no charge during storage, so the lantern is ready to use after extended periods without recharging.

What static leakage current did the ETENWOLF CL3 measure?

In this test, Sample 1# measured 1.4 μA and Sample 2# measured 1.6 μA, both recorded with the unit in the powered-off state at 23 °C and 60 % relative humidity.

What test equipment was used to measure the CL3’s static current?

A multimeter configured on the micro-ampere (μA) range was used, connected in series with the battery circuit while the CL3 was switched off.

Did the CL3 pass the static leakage current test?

No formal pass/fail threshold is defined for this test under the internal standard; the results (1.4 μA and 1.6 μA) are recorded for reference only and serve as a baseline for future comparison and product validation.
