Sanyo SEB-013SEB-013 Wide Operating Temperature Range, Charging Possible with, Excellent Continuous Charging Performance, Superior Overcharging Performance

Superior Charge/Discharge Characteristics (ML2430)

Our batteries can withstand 20,000 cycles, 3,000 cycles and 500 cycles under discharge conditions of 1.0mAh (discharge depth of 1％), 5.0mAh (discharge depth of 5％) and 20mAh (discharge depth of 20％) respectively.

Wide Operating Temperature Range

The use of an organic electrolyte gives an extended operating temperature range: －20℃ to ＋60℃.

Charging Possible with 2.8V

Even a charging voltage as low as 2.8V ensures high charge efficiency.

Excellent Continuous Charging Performance

Stable characteristics are maintained even when continuously charged for long periods.

Superior Overcharging Performance

The use of an organic solvent rather than an alkali for the electrolyte and superior sealing technology significantly reduce the risk of leakage.

Small Self-Discharge Rate Assures Durability

The self-discharge rate of approx. 2% per year at room temperature is much lower than that of Ni-Cd button cells. Even after five years of storage at room temperature, you can expect about 90% of the original capacity.
