Main performance parameters of alkaline batteries:
1, voltage: open circuit voltage that is no-load voltage generally in 1.6 V, high can reach 1.725 V, nominal voltage in 1.5 V; 2, discharge capacity: in general, alkaline batteries are represented by the discharge time under a typical discharge regime. For example, the No. 5 alkaline cell can last for six hours, discharge at a low current (equivalent to 10 ω) , and have a capacity of about 1,800 to 2,000 mah; the No. 7 alkaline cell can last for 2.5 to 3 hours, the low current discharge capacity is about 800 to 1200 mah. This capacity specification is based on a voltage value, with the alkaline battery terminating at 0.9 V at full power.
