Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
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.
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.
Make sure you measure the correct way: connect the poles to their corresponding measuring ends.
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.
Expiry date indicates how long the battery will function properly according to industry standards.
Lithium batteries can give off a strong energy surge after a long period of low discharge, making them ideal for fire alarms.
0006P is a 9V (square) battery and is also designated as a 6F22 (Zinc carbon) or 6LR61 (Alkaline) battery.
This is a guarantee that no mercury is added during production.
If service time has reduced to half of its initial capacity or if charging time never seems to complete, it’s probably time to replace the battery.
