Frequently Asked Questions

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

In case of skin contact there is a chance of chemical burns. Use clear tepid water for at least 15 minutes on 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 and consult a medical professional immediately.
Battery leakage is caused by forcefully discharging, short-circuiting, or the safety valve releasing excess gas from inside the cell.
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. If you start using it within that period, the battery will operate normally and maintain the specified performance.
A hot battery could have several causes: from wrong storage to short circuiting. Some warmth is okay but keep an eye out for unusual heat.
Empty batteries should always be recycled. You can bring your batteries to a recycling point near you, free of charge.
This is a guarantee that no mercury is added during production.
Panasonic does not produce or sell 12V batteries like A27, 27A, G27A, MN27 or bi09 of other manufacturers. These types of batteries look very similar to AAA-size 1.5V batteries. However, they are not compatible due to different voltages. We do offer 12V LRV08, which is similar to the MN21 or A21.
Mixing batteries causes an imbalance in the energy flow. Some batteries will overcompensate this by discharging faster than usual - greatly reducing their lifespan.
Make sure you measure the correct way: connect the poles to their corresponding measuring ends.
Mixed use or leaving the battery in the appliance can cause battery leakage.
