At this point Panasonic does not produce AAAA or LR61 batteries.

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.

In case of skin contact there is a chance of chemical burns. Use clear tepid water for at least 15 minutes 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.

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

Due to chemical reactions inside most batteries, the stored charge of the batteries is reduced little by little.

There are some best cases to keep stored batteries in best shape: store them in their original packaging, never mix up different batteries and store them at room temperature or in a cool environment.

Mixed use or leaving the battery in the appliance can cause battery leakage.

There are different types of batteries, for instance Zinc Carbon and alkaline. If the previous battery was an alkaline, and the new ones are Zinc carbon, it is possible that the capacity and thus lifespan is less.

Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.
