Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
Each battery has specific characteristics, depending on their chemical composition. Zinc carbon is a cheap battery for basic low-drain devices. Alkaline deliver good, dependable power (usable for any type of device, depending on the alkaline type). Lithium technology is a stable technology for smaller, yet demanding appliances. Zinc Air provide long-lasting, continual power.
It’s possible, yes. But we can never guarantee perfect functionality - so we recommend charging your Panasonic batteries with a Panasonic or eneloop charger.
For best performance, always try to keep the battery’s energy level above 30% of its total capacity. Also: always use batteries of the same type and expiry date together.
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.
Never throw batteries in the trash. All batteries, including Panasonic hearing aid batteries, can and should be recycled.
In general it’s best to never let your batteries deplete completely. Try to recharge them before the energy level drops below 30%.
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.
No. However commonplace they may be, they’re still made up of chemicals that can potentially harm the environment (and the user) if they’re handled incorrectly.
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.
While leakage is rare, it may still occur if the battery is used incorrectly. Leakage is usually caused by leaving the battery in an unused device or short-circuiting.
