Frequently Asked Questions - HA20 Nitecore

What battery type does the Nitecore HA20 use?

The HA20 is compatible with one 18650 rechargeable Li-ion battery or two CR123 primary cells. For optimal performance, use Nitecore NL1835 series batteries.

How do I switch between brightness modes?

Press the tail switch fully to turn on/off. Half-press to cycle through Turbo, High, Mid, Low, SOS, and Beacon modes.

What is the maximum brightness of the HA20?

The HA20 delivers a maximum output of 1000 lumens in Turbo mode, with a beam distance of 150 meters.

Is the flashlight waterproof?

Yes, it has an IPX8 rating and can be submerged up to 2 meters in water.

How can I maintain the flashlight?

Regularly clean the battery contacts with a cotton swab and isopropyl alcohol. Lubricate the threads and O-rings with thin silicone grease every few months.

What should I do if the flashlight flickers?

Flickering usually indicates loose battery connection or low battery. Tighten the tail cap or recharge/replace the battery.

Can I use the HA20 with a headband?

The HA20 is designed as a handheld flashlight but can be used with an optional Nitecore HB-20 headband for hands-free use.

Is there a lockout function?

To prevent accidental activation, loosen the tail cap by a quarter turn to physically disconnect the battery.

How do I replace the O-rings?

Remove the old O-ring gently with a plastic tool. Stretch the new spare O-ring over the groove and lubricate lightly. Ensure it sits evenly.

What safety precautions should I take?

Never stare directly into the beam as it can cause eye damage. Do not leave the flashlight unattended on Turbo mode for extended periods to avoid overheating.

Operating Instructions

HA20 utilizes a two-stage switch to enable various operations based on finger pressure.

Battery Installation

Insert two AA batteries with the positive (+) and negative (-) ends corresponding to the diagram below. Align the cover.

Note: Each time batteries are inserted, the red LEDs will blink to indicate battery voltage. Please refer to the "Power Tips" section in this manual for details.

Caution: DO NOT direct the beam towards human or animal eyes when using HA20.

On/Off Operations

To turn HA20 on: Press the switch all the way down until a "Click" is heard;

To turn HA20 off: Press the switch all the way down again until a “Click” is heard.

Brightness Levels

With HA20 turned on, press the switch partway down to cycle through brightness levels: ultralow, low, medium, high-turbo. HA20 has memory effect for brightness levels. Each time it is turned on, HA20 will enter the brightness level last used.

Special Modes(Police Warning/Location Beacon/SOS)

With HA20 turned on, press the switch all the way down for over one second to enter police warning mode. Press the switch partway down to cycle through location beacon-SOS-police warning modes. To exit, press the switch all the way down to turn HA20 off.

Constant/Flashing Red Illumination

With the light turned off, press the switch partway down for over one second to enter constant red illumination mode (7 hours and 25 minutes runtime at 16 Lumens);

In red illumination mode, press the switch partway down to switch between constant and flashlight red illumination. To exit, press the switch all the way down to turn HA20 off.

Power Tips

Upon battery installation, the red LEDs will blink to indicate battery voltage (accurate to 0.1V). For example, when battery voltage is 2.4V, red LEDs blink twice, followed by a 1.5 second pause, and blink four

times.

With HA20 turned off, pressing the switch partway down will have red LEDs indicate battery power levels:

1. Three times for battery levels over 50%;
2. Twice for battery levels below 50%;
3. Once for battery levels close to depletion (below 10%).

Advanced Temperature Regulation (ATR)

Advanced temperature regulation (ATR) technology allows HA20 to dynamically adjust output performance based on its internal temperature. This prevents damage from overheating and prolongs its working life.

Changing Batteries

Batteries should be replaced when any of the following occurs: The output appears to be dim or unresponsive.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.
