Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.

In case of skin contact there is a chance of chemical burns. Use clear tepid water for at least 15 minutes on exposed skin. Consult a physician in case of irritation, injury or pain. In case of contact with the eye, do not rub the eyes, but flush with clear tepid water for at least 30 minutes and consult a medical professional immediately.
Turn off the device and remove the battery immediately. Remove the remaining leakage using a cotton swab. Avoid skin contact at all times.
Batteries are classified according to IEC classification standards: LR03 is equal to AAA, but in another standard.
A hot battery could have several causes: from wrong storage to short circuiting. Some warmth is okay but keep an eye out for unusual heat.
Avoid contact with the substance at all times. Place the batteries into a plastic bag before recycling them. Clean out the battery holder with a dry cotton swab. In case of contact, wash your hands thoroughly with soap and water.
Batteries will become unfit to use after they’ve been in the water. Usually however, a battery won’t leak inside the washing machine thanks to the safety valve - so chances of your textile being affected are minimal.
Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.
If service time has reduced to half of its initial capacity or if charging time never seems to complete, it’s probably time to replace the battery.
Never mix batteries. Mixing batteries causes an imbalance in the energy flow. Some batteries will overcompensate this by discharging faster than usual - greatly reducing their lifespan.
