Comparison of Performance of Class 6 Batteries

1, zinc manganese battery: high voltage(open circuit voltage of new battery up to 1.5 V), cheap, but minimum capacity, internal resistance, poor stability; Waste batteries pollute the environment.

2, alkaline battery: high voltage(open circuit voltage of new battery up to 1.5 ~ 1.6 V), large capacity, Good stability, long placement time, excellent performance of small current discharge, especially for environments that require small current discharge for a long time(such as quartz clocks, radios). However, the low temperature performance is not good, and the high current discharge effect is not good(single can be used for flash without current protection), and the waste battery is contaminated with the environment.

3, lithium batteries: high voltage(different battery voltage of different specifications), large capacity, good stability, long placement time, large current and small current discharge performance are good; In use, the voltage remains stable for a long time and falls slowly; Waste batteries cause serious environmental pollution.

4, nickel-cadmium batteries: Voltage is lower than alkaline batteries and zinc-manganese batteries(normal voltage 1.2 V, voltage up to 1.3 V at full charge); Compared with nickel-metal hydride batteries, the price is appropriate, but the capacity is smaller than nickel-metal hydride batteries; Low internal resistance and poor stability; There's a distinct memory effect. Charging dissatisfaction or incomplete discharge will affect the battery's capacity, poor low temperature performance, and poor discharge effect. Careful charging can repeatedly charge 200-500 times; Waste batteries cause serious pollution to the environment.

5, nickel-metal hydride batteries: Voltage is lower than alkaline batteries and zinc manganese batteries(normal voltage is 1.2 V, voltage can reach 1.3 V when it is fully charged); However, the capacity is large, the internal resistance is small, and the stability is good; The charging current is large, the charging time is short, the endurance is strong, there is no obvious memory effect; Good low temperature performance and excellent high current discharge(very suitable for Flash, digital camera, mobile phone and laptop); Careful charging can be repeated more than 500 times. Good nickel-metal hydride battery Ruwaerta(VARTA), can charge 1,000 times, even 1200 times; Waste batteries have little serious environmental pollution.

6, Lithium-ion batteries: high voltage(different battery voltage of different specifications), large capacity, small internal resistance, good stability; High current discharge performance is good; In use, the voltage remains stable for a long time, but once the power is exhausted, the voltage will drop to 0; There is no memory effect at all. Charging dissatisfaction or incomplete discharge will not affect the battery's capacity, low temperature performance, low current discharge effect, and careful charging can repeatedly charge 400-500 times; Waste batteries cause serious environmental pollution.
