Frequently Asked Questions

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

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.
Battery performance greatly depends on the device and on the conditions.
They do. We guarantuee performance for up to three years after production. After this we cannot guarantee the battery will perform as well as it’s supposed to.
Assuming your device isn’t faulty, causes may lie in either improper contact with the terminal or in the batteries themselves.
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.
Zinc air battery are different from other batteries. They do not contain active materials in their positive electrode. This type of battery reacts with air - so it’s important to remove the tag before inserting the battery into your device. They provide a current of 1.4V if used correctly.
Yes. All batteries have an expiration date, beyond which their performance decreases.
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.
Make sure you measure the correct way: connect the poles to their corresponding measuring ends.
