Frequently Asked Questions

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

The revised RoHS (Reduction of Hazardous Substances) Directive 2011/65/EU...
A battery is a chemical product which produces electricity by chemical reactions at its inside. These reactions and its inside materials do deteriorate over time. If you start using it within that period, the battery will operate normally and maintain the specified performance.
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.
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.
Batteries are classified according to IEC classification standards: LR03 is equal to AAA, but in another standard.
Yes. All batteries have an expiration date, beyond which their performance decreases.
Expiry date indicates how long the battery will function properly according to industry standards.
Make sure you measure the correct way: connect the poles to their corresponding measuring ends.
Turn off the device and remove the battery immediately. Remove the remaining leakage using a cotton swab. Avoid skin contact at all times.
