The Panasonic AA batteries have advanced long-lasting energy. This technology makes the AA batteries perfectly suitable for high and medium drain appliances. Devices such as high-energy camera strobes, radio-controlled cars and torches can be used for a long time. Panasonic AA cells feature advanced Anti-Leak Protection that suppresses gas build-up when a battery is over-discharged or stored for a long period. Less pressure means less chance of structural failure and rupture and protects your valuable devices from damage.
