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

The main difference between a zinc battery and an alkaline battery is the type of electrolyte used in both batteries. Because of the composition, an alkaline battery delivers more energy than a zinc battery. Both batteries should thus be used in different appliances.

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.

It is not recommended as this could lead to over-discharging the batteries, which is one of the main causes of shortening the service life of your batteries.

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

Battery leakage can be caused by various problems. Read on to learn more.

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.

As new energy flows into your battery, some heat is perfectly fine. If you notice the battery or charger becomes too hot to touch, cease the charging process immediately.

This is a vibration noise which occurs when electric current flows through a transformer or a winding wire inside a component part. However, the charger may still be used without any concern as there is no need to worry from a safety point of view.

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.
