Frequently Asked Questions

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

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.
Due to chemical reactions inside most batteries, the stored charge of the batteries is reduced little by little. This phenomenon is called self-discharge.
Perhaps you are using a different battery type. Zinc carbon will perform otherwise compared to alkaline, for example.
Make sure you measure the correct way: connect the poles to their corresponding measuring ends.
Zinc carbon batteries are more commonly used in low-drain devices, whereas the Panasonic alkaline range spans the entire appliance spectrum: from low- to high-drain.

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.
Batteries are classified according to IEC classification standards: LR03 is equal to AAA, but in another standard.
This should be avoided at any time. When the battery has been in a washing machine, it is no longer fit to use. Please dispose of this battery.
