Some common non-warranty issues that can be easily checked.
- Batteries placed in the wrong way or reversed polarity. (Especially an issue with LED fitted head torches, as LEDs are polarity sensitive).
- Corrosion, from leaking batteries, exposure to salt, chemicals etc. Non-warranty issue sometimes repairable though can be too corroded to repair.
- Loose bulbs and bulb contact has build up, goodwill repairs.
- Flat batteries.
- Bezel reflector is crazed, opaque (not shiny). This is usually caused by battery leakage or water leaking into the head torch and not being dried out afterwards.
Lithium Battery Information
Limitations on use of AA/LR6 and AAA/LR03 Lithium batteries with headlamps.
This information does not apply to the e+Lite which was designed to work with CR2032 Lithium batteries.
Lithium batteries are lighter and give longer burn times at low temperature than traditional Alkaline batteries.
Due to recent advances in the performance characteristics of Lithium batteries (especially their higher output during discharge), they can cause the lamp to overheat and possibly damage the LEDs.
You can use AA/LR6 Lithium batteries with the following lamps:
- MYO range: MYOBELT SB5 / MYO / MYOLITE.
- DUO range: DUO LED 14.
- Others: SAXO / MICRO / ZOOM Halogène.
- Discontinued headlamps: MYO 5, DUO LED 8.
Attention: the use of Lithium batteries reduces the lifespan of incandescent bulbs.
Do not use Lithium batteries with the following lamps:
- TIKKA / ZIPKA range: TIKKINA / TIKKA / ZIPKA / TACTIKKA / TIKKA PLUS / ZIPKA PLUS / TACTIKKA PLUS / TIKKA XP / TACTIKKA XP / TIKKA XP
- ATEX / TIKKA XP HAZLOC.
- MYO range: MYOLITE 3 / MYO 3 noir / MYO XP.
- DUO range: DUO LED 5.
- SAXO AQUA.
- Discontinued headlamps: MYOBELT 3, DUO LED 3.
Reversing the polarity of a battery is dangerous and can cause explosions and chemical burns.
It's absolutely necessary to correctly insert the batteries in the battery case, making sure to follow the diagrams on the battery case in regards to the polarity of the batteries.
A battery inserted the wrong way can explode.
If the polarity of one battery is reversed in the battery case (with two ends in contact with one another or two positive (+) ends in contact with each other) it's actually being charged by the other batteries. This causes a chemical reaction inside the reversed battery. Within the span of a few minutes, the battery can leak explosive gases and/or extremely corrosive liquids. There's also a danger of explosion and chemical burns.
Indication: a weak level of light
If a headlamp with fresh batteries emits a weak light, it means that one or more of the batteries could be reversed.
What to do?
- Immediately turn off the headlamp and check the polarity of the batteries.
- Precautions must be taken when opening the battery case in the event a leak has already occurred or occurs while opening the case.
- If you come in contact with the liquid from the batteries, immediately rinse the affected area with running water and seek medical help.
