2. What is the meaning of the “mAh” on my rechargeable batteries?
The capacity of batteries is indicated as XXXX mAh (milliampere/hour). The formula for calculation is as follows: Capacity (milliampere/hour) = discharge (milliampere) x discharging time (hour) E.g. Take a Ni-MH rechargeable battery with a capacity of 2000 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. However, this is just a guideline since it varies depending on the performance of the appliance or the conditions it is used in.
3.Can I charge my Alkaline or Zinc Carbon battery?
Don’t charge an alkaline or Zinc Carbon battery, they are not designed to be charged. If charged there is a high risk of leakage or explosion of the battery. If something would happen during charge of Alkaline or Zinc Carbon primary batteries, the manufacturer cannot be held responsible. In case you would like to reuse your batteries, we recommend to buy our rechargeable batteries.
4. I accidentally washed my clothes together with some batteries.
This should be avoided at any time. When the battery has been in a washing machine, it is no longer fit to use. It is likely that the battery has short circuited and/or that it will start oxidizing quite fast, in which case leakage and additional short circuiting is possible. Please dispose of this battery. It is always recommended to rewash the clothes.
