Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
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.
Panasonic hearing aid batteries, or zinc air batteries, react with air. As soon as you pull off the seal, the battery will be able to release energy. Be sure to let the battery breathe for a few minutes before inserting it into your device.

The revised RoHS (Reduction of Hazardous Substances) Directive 2011/65/EU...
Turn off the device and remove the battery immediately. Remove the remaining leakage using a cotton swab. Avoid skin contact at all times.
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.
Yes. All batteries have an expiration date, beyond which their performance decreases.
Lithium batteries can give off a strong energy surge after a long period of low discharge, making them ideal for fire alarms.
Batteries will become unfit to use after they’ve been in the water. Usually however, a battery won’t leak inside the washing machine thanks to the safety valve - so chances of your textile being affected are minimal.
