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.

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.

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.

Make sure you measure the correct way: connect the poles to their corresponding measuring ends.

Batteries are classified according to IEC classification standards: LR03 is equal to AAA, but in another standard.

Always insert batteries with the poles in the correct direction. Not doing so will lead to a short circuit.

Mixed use or leaving the battery in the appliance can cause battery leakage.

Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.

Turn off the device and remove the battery immediately. Remove the remaining leakage using a cotton swab. Avoid skin contact at all times.

Expiry date indicates how long the battery will function properly according to industry standards.
