Ultra-low self-discharge
Our intensive research yields a more effective choice of electrolyte solvent, which forms a protective film over lithium to prevent ionization and self-discharge while in storage. In addition, calcination treatment conditions were set to prevent MnO2 from leaching into the electrolyte, slowing the rate of self-discharge. Panasonic Lithium batteries boast a self-discharge rate of less than […]

Reliable in a wide range of temperatures
Various design aspects combine to preserve high capacity after long-term storage while enabling safe use down to -40 °Fahrenheit. Organic materials reduce the electrolyte solidification point to less than other battery types, optimizing storage and operation in low temperatures, while high-purity MnO2 has the optimal particle-size for high-rate discharge at low temperatures. Gas-suppressing materials, meanwhile, preserve […]

Safety system technology
Panasonic’s exclusive safety structure prevents short-circuits and leaks with fail-safe protections for over-current, over-voltage, and overheating, even if the battery is damaged. The system includes a thermosensitive PTC that detects temperature rises and increases resistance to prevent short-circuit, a built-in safety valve to relieve internal pressure, and durable gasket material that’s effective at preventing leaks. […]

High energy formula
Our High Energy Formula contributes to Panasonic Lithium’s long-lasting endurance in mid and high-drain applications, such as cameras, where the battery’s low internal resistance helps to reduce flash-recovery times for rapid burst shooting. High-purity MnO2 is filled at high density, extending life, while the corrosion-resistant stainless cathode core stabilizes discharge at high voltage. The lithium anode […]

Faster flash charging and longer life
External camera flash units demand short, strong bursts of power, requiring time for their capacitors to be refilled. That delay could make you miss the shot of a lifetime. eneloop pro batteries refresh your flash much faster than regular alkaline batteries. Flash units powered by eneloop batteries can even be set to burst mode, allowing […]

Consistent discharge performance
eneloop Ni-MH AA and AAA batteries maintain a consistent level of 1.2V power throughout the entire life of the charge. While alkaline chemistry batteries rated at 1.5V, the voltage rapidly drops below the NiMH rating of 1.2V and decreases the amount of power going to the device.
