Battery leakage is caused by forcefully discharging, short-circuiting, or the safety valve releasing excess gas from inside the cell.

Turn off the device and remove the battery immediately. Remove the remaining leakage using a cotton swab. Avoid skin contact at all times.

Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.

Mixing batteries causes an imbalance in the energy flow. Some batteries will overcompensate this by discharging faster than usual - greatly reducing their lifespan.

Expiry date indicates how long the battery will function properly according to industry standards.

Avoid contact with the substance at all times. Place the batteries into a plastic bag before recycling them. Clean out the battery holder with a dry cotton swab. In case of contact, wash your hands thoroughly with soap and water.

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.

This is a guarantee that no mercury is added during production.

Perhaps you are using a different battery type. Zinc carbon will perform otherwise compared to alkaline, for example.
