Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
Batteries are best stored at room temperature. Extreme heat or cold can significantly reduce battery life.
Never try to charge Panasonic lithium coin batteries, as they cannot be recharged.
In appliances without a charging function, yes. In appliances that do have a charging function, be sure to check whether the function was specifically designed for Ni-MH. If not, it’s best not to use Ni-MH batteries.
Cycle life is the number of times the rechargeable battery can be recharged.
Mixed use or leaving the battery in the appliance can cause battery leakage.
When replacing a coin battery, make sure you do the following: insert it the correct way, with plus and minus poles touching the right terminals; use the right coin battery size; avoid dirt or any other substances obstructing proper contact; carefully insert the coin, not putting stress on it as you’re closing up the holder.
Batteries are chemical products which internally undergo certain chemical processes over time. Due to this process some batteries slightly discharge during storage.
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.
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.
At this point Panasonic does not produce AAAA or LR61 batteries.
