Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
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.
While most batteries will still work in extreme temperatures (albeit with shorter lifespans), Panasonic EVOLTA NEO is your best choice for extreme cold or warm weather.
Zinc air battery are different from other batteries. They do not contain active materials in their positive electrode. This type of battery reacts with air - so it’s important to remove the tag before inserting the battery into your device. They provide a current of 1.4V if used correctly.
Batteries are chemical products which internally undergo certain chemical processes over time. Due to this process some batteries slightly discharge during storage.
At this point Panasonic does not produce AAAA or LR61 batteries.
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.
Batteries are best stored at room temperature. Extreme heat or cold can significantly reduce battery life.
Never mix batteries. 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.
