Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
Yes. All batteries have an expiration date, beyond which their performance decreases.
As new energy flows into your battery, some heat is perfectly fine. If you notice the battery or charger becomes too hot to touch, cease the charging process immediately.
Panasonic does not produce or sell 12V batteries like A27, 27A, G27A, MN27 or bi09 of other manufacturers.
The capacity of batteries is indicated as XXXX mAh (milliampere/hour). If you insert this battery into an appliance which consumes 100 milliampere current continuously, the operating time of the appliance will be around 20 hours mathematically.
If service time has reduced to half of its initial capacity or if charging time never seems to complete, it’s probably time to replace the battery.
Make sure you measure the correct way: connect the poles to their corresponding measuring ends.
Always insert batteries with the poles in the correct direction. Not doing so will lead to a short circuit.
This is a vibration noise which occurs when electric current flows through a transformer or a winding wire inside a component part. However, the charger may still be used without any concern as there is no need to worry from a safety point of view.
Never charge Ni-MH batteries with a Ni-Cd charger. There are significant differences in charging conditions between those two types of batteries.
0006P is a 9V (square) battery and is also designated as a 6F22 (Zinc carbon) or 6LR61 (Alkaline) battery.
