Alkaline power micro pencil battery (AAA) 4 pcs.

Panasonic batteries KEEP CHARGE FOR 10 YEARS AND ARE FREE OF ELECTROLYTE LEAKS! As Panasonic battery launches on the European consumer market, the new battery packaging and increased performance visibility on the package will be available across the entire range, reflecting the company's core values, high professional standards and technological orientation.

Alkaline battery leaks are largely caused by the formation of hydrogen gas in the battery when it is excessively discharged during use or storage. The gas increases the pressure inside the element and this can lead to leakage. Anti-leakage technology reduces the amount of gas produced and helps prevent the battery from leaking.

To emphasize the reliability of the batteries, Panasonic has introduced a "10-year performance protection" logo, which states that Panasonic batteries will continue to function even after a long period of storage if they have not been used and stored properly. This means that batteries bearing this logo have a shelf life of 10 years and will retain their charge for up to a decade after manufacture, provided they are not used and stored properly.
