Frequently Asked Questions

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

Mixing batteries causes an imbalance in the energy flow. Some batteries will overcompensate this by discharging faster than usual - greatly reducing their lifespan.
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.
By recycling your batteries, you actively help reduce landfill waste. Up to 90% of the materials in Panasonic batteries can be reused to make new batteries or processed in other industries.
Never throw batteries in the trash. All batteries, including Panasonic hearing aid batteries, can and should be recycled.
Replace all batteries at the same time. Do not mix old and new batteries. Use batteries from the same brand, type and expiry date too.
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.
You can, but they’ll perform best in medium- to high-drain devices.
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.
In general, appliances are designed to match the characteristics of dry batteries and to work within the voltage range of 1.5V to 0.9V. Thanks to this characteristic, Ni-MH rechargeable batteries can be used in appliances which require alkaline batteries, even with lower initial voltage. 
No. Do not use batteries in water or in vacuum conditions - this will cause them to rust and short-circuit.
