Frequently Asked Questions

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

Because there is a slight difference between manufacturers. Always use the previously used type of batteries which did fit in the compartment in case the batteries do not fit.
In case of skin, eye contact with alkaline solution or electrolyte from zinc carbon battery: irrigate exposed skin with clear tepid water for at least 15 minutes, if irritation, injury or pain persists, contact a physician. If there is contact with the eye, do not rub the eyes, but flush the eyes with clear tepid water for at least 15 min.
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.
To properly dispose the battery please consult and follow the rules of your local government.
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. 
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.
Mixed use or leaving the battery in the appliance can cause battery leakage.
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.
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.
Yes, the batteries' weight does change during usage.
