Frequently Asked Questions

Following Q&A will teach you everything you wanted to know about batteries and how to optimize the usage.
Cycle life is the number of times the rechargeable battery can be recharged.
A hot battery could have several causes: from wrong storage to short circuiting. Some warmth is okay but keep an eye out for unusual heat.
This is a guarantee that no mercury is added during production.
A battery is a chemical product which produces electricity by chemical reactions at its inside. These reactions and its inside materials do deteriorate over time. If you start using it within that period, the battery will operate normally and maintain the specified performance.
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.
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.
Batteries are classified according to IEC classification standards: LR03 is equal to AAA, but in another standard.
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.
Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.
Yes. All batteries have an expiration date, beyond which their performance decreases.
