Frequently Asked Questions

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

0006P is a 9V (square) battery and is also designated as a 6F22 (Zinc carbon) or 6LR61 (Alkaline) battery.
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.
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.
Our batteries are produced without adding Mercury during the production process.
When it comes to frequently used remotes or appliances, the batteries are quite fast changed after the appliance or remote stopped working, because it is easy noticeable. However if the appliance or remote is not that often used, there is a risk of over discharge and leakage in that appliance. 
There is the possibility that the measurement was executed wrongly. Please make sure that the plus pole and the minus pole are measured with the corresponding measuring ends of the voltmeter. If they are switched, there will be a negative voltage. If the poles of your voltmeter are correctly connected, there is a possibility that the battery suffered a phenomenon called “polarity reversal”. This is a rare phenomenon that can happen at the end of a discharge with 2 or more batteries in series.
Batteries are chemical products which internally undergo certain chemical processes over time. Due to this process some batteries slightly discharge during storage.
The revised RoHS (Reduction of hazardous Substances) Directive 2011/65/EU...
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.
