Features Low cost; variety of Service capacity at High efficiency under High service Moderately flat voltage
shapes and sizes moderate to high current moderate and high capacity-volume ratio; discharge characteristics
drains greater than carbon- continuous conditions; flat voltage discharge
zinc; good leakage good low-temperature characteristic; good high
resistance; low-temperature performance; low temperature
performance better than impedance
