Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
No. All Panasonic rechargeable batteries come pre-charged. However, due to changes in conditions and temperature during transportation, some discharge may have occurred - meaning the battery may not be at full capacity when you take them out of the package.
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.
No. Do not use batteries in water or in vacuum conditions - this will cause them to rust and short-circuit.
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.
Panasonic does not produce or sell 12V batteries like A27, 27A, G27A, MN27 or bi09 of other manufacturers.
Yes, Ni-MH rechargeable batteries can be used for (torch) lights with a wire filament.
Panasonic zinc air batteries have been specifically designed for hearing aids, other batteries may not perform as well.
Always remove batteries from devices you don’t use for longer periods, from devices connected to AC power and when batteries are empty.
Whereas some size change is perfectly normal, it should not be overly pronounced. If so, replace the battery immediately. A bulging coin battery may lead to device malfunction and even short-circuiting.
Perhaps you are using a different battery type. Zinc carbon will perform otherwise compared to alkaline, for example.
