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.

Our batteries are produced without adding Mercury during the production process.

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.

0006P is a 9V (square) battery and is also designated as a 6F22 (Zinc carbon) or 6LR61 (Alkaline) battery.

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 this battery.

Typically for an alkaline battery is a gradually decreasing voltage when it discharges, which means that for some appliances, which need a high base voltage to operate, the appliance stops working even while the battery has still a bit of energy left.

Batteries are chemical products which internally undergo certain chemical processes over time. Due to this process some batteries slightly discharge during storage.

Yes the batteries weight does change during usage.
