Battery Safety Precaution

Ensure the protection circuit on the 18650 battery to have current trip of 10A or higher (EAGTAC 18650 2600mAh and 3500mAh (Sanyo GA cells) with protection PCB built-in at anode both have 10A trip current). Always use proven EAGTAC batteries for best performance and reliability. Safe chemistry IMR 18650 li-ion are also supported, however use it with precaution as they are unprotected.

All EAGTAC flashlights are designed to use button-top battery (battery with protruding positive terminal). For rechargeable li-ion battery, use only EAGTAC li-ion battery, or other protected li-ion battery with compatible length and diameter. Before using the battery, check and ensure the battery outer wrapping (the isolating plastic film that wraps around the metal housing of the battery) is complete. Broken battery wrapping may lead to short circuit and damage to the flashlight.

Lithium and Li-ion battery can explode or cause burns if disassembled, shorted, or exposed to high temperature. Do not mix new and used batteries. Do not mix batteries with different brand, capacity, voltage, or install batteries backwards.

NiMH rechargeable battery may release gas during discharge. If you experience an inflated switch boot or find high pressure being built inside the flashlight, switch off the flashlight immediately. Slowly loosen the tail-cap to reduce the internal pressure and replace all batteries.     Back to top

Flashlight Maintenance

Periodically clean the threads and o-rings with a lint free cloth and apply a thin coating of EAGTAC synthetic grease to the o-rings and threads. After prolonged exposure to moisture, the head and batteries should be removed, inspected, and dried. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently.     Back to top

  1. This weight measurement is based on the Kit model excluding batteries
  2. All batteries must have protruding top button. Protected li-ion battery with 2.5V low voltage cut-off setting is recommended. Using li-ion battery with higher cut-off value (e.g. 3V) may cause the LED to blink when the battery is almost drained due to battery restarting itself. This is normal.
  3. Beam output diameter taken at one meter
  4. ANSI FL-1 Lumens is a measurement of light output standardized by American National Standards Institute for use with flashlights. This ANSI Lumen measurement is the total overall light output being emitted from the flashlight measured in a calibrated integrated sphere. This measurement is generally more accurate as it takes into consideration the loss from reflector/lens/bezel.
  5. After 60 seconds at maximum output level (100%), the active thermal management feature will be activated and continuously adjusts the maximum output level according to the flashlight internal tempearture. The C3800 adjustment output range is between 80% to 100% (72%-100% for W1900). This feature maintains the flashlight surface temperature to be about 130°F (54 °C) for C3800 or 140°F (60 °C) for W1900 (higher surrounding temperaturemay result in higher flashlight temperature). It's normal for high power flashlight to run hot at MAX level. Reduce the output if the user finds the flashlight too warm to hold.
  6. Runtime is measured using one EAGTAC 3500mAh high discharge 18650 li-ion batteries. MAX level runtime includes out-of-current regulation time period when battery is almost depleted. With active thermal management feature, runtime in cooler environment will have shorter runtime (higher MAX output) and long runtime in hotter environment (lower MAX output).
