Frequently Asked Questions

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

A decreased operating time could indicate that your rechargeable batteries need replacing, depending on the circumstances.
It is not recommended as this could lead to over-discharging the batteries, which is one of the main causes of shortening the service life of your batteries.
Whereas some heat is normal, unusually hot batteries could be caused by over-discharging or short-circuiting. In such case, remove them from the device immediately.
Polarity reversal may happen when more than two batteries are connected in series and used until the last moment of discharge.
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.
Yes, Ni-MH rechargeable batteries can be used for (torch) lights with a wire filament.
Panasonic EVOLTA NEO is your best choice for high-drain devices. Thanks to more precise manufacturing, increased density and silver compounds, the battery will greatly outperform other batteries.
Battery lifespan greatly depends on the device and on the conditions.
Any minor difference in the batteries will cause either batteries to overcompensate and to deplete faster.
