Frequently Asked Questions

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

Coin batteries have a low voltage (1.5 V) and a diameter less than 12 mm to prevent any serious accident. Also, packaging has been designed specifically to prevent accidental ingestion. Panasonic coin batteries are thus relatively safe and serious accidents are very uncommon.
Zinc carbon batteries are more commonly used in low-drain devices, whereas the Panasonic alkaline range spans the entire appliance spectrum: from low- to high-drain.
Panasonic strongly advocates not attempting to charge primary batteries such as alkaline, zinc carbon, or lithium, using Ni-MH chargers. Alkaline batteries are not designed for recharging, and doing so could cause leakage and in the worst case lead to the batteries exploding.
Use batteries for their right purpose: insert them correctly, replace them when empty and store them dry and at room temperature.
Battery leakage can be caused by various problems. Read on to learn more.
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.
Battery performance greatly depends on the device and on the conditions.
Panasonic does not produce or sell 12V batteries like A27, 27A, G27A, MN27 or bi09 of other manufacturers.
