subject: nickel-cadmium battery memory effect [print this page] Third, to conserve Note Third, to conserve Note
1. At -30 ~ 50 within the temperature range between the preservation, but if it is time to place the case for the following stored at 35 ;
2. State of charge or discharge state of preservation is possible, but the comparison can discharge capacity of the state, and easier to be activated earlier reply; asus Laptop Batterycompaq Laptop Battery
3. When the battery is placed in a long time, use the former to be very in charge before use.
When the nickel-cadmium batteries to repeat after a few remained at a low discharge capacity after charging, if you have to do a large amount of discharge the battery will not work, this situation we call "memory effect." Memory effect of nickel-cadmium batteries may be the most easily misunderstood the issue. Discharge termination voltage is set higher video recorder, with the use of the voltage change is low, the surface may seem as lower, but the low discharge voltage can be from 1 to 2 times the total discharge of the solution to this phenomenon. Ten after the proposed charging a discharge, to prevent the proposed effect.
5, nickel-cadmium batteries and nickel-hydrogen battery comparison
Nickel-cadmium battery is the first mobile phones, notebook computers, and other battery types, it has good high-current discharge characteristics, resistance to charging and discharging capability and simple maintenance. Nickel-cadmium battery is fatally flawed, in the charge-discharge process if not handled properly, there will be serious "memory effect", so service life shortened. In addition, cadmium is toxic and therefore not conducive to nickel-cadmium batteries to protect the environment. Many shortcomings make nickel-cadmium batteries have basically eliminated the application of digital device battery.
2. Ni-MH battery (Ni-MH Batteries): IBM thinkpad r51 battery Thinkpad r50 battery IBM thinkpad r32 battery Thinkpad x41 battery
Ni-MH battery is the early alternative to nickel-cadmium battery, which is the most environmentally friendly battery, no use of toxic cadmium, can eliminate the heavy metals pollution on the environment. Ni-MH batteries have greater the energy density ratio, which means that you can Zai digital devices without additional weight to the case, with Ni hydrogen battery can effectively to the Gong Zuo Yan Zhang equipment time. At the same time in the electrical properties of Ni-MH battery with the nickel-cadmium batteries are also similar, in actual use can replace nickel-cadmium ThinkPad G41 battery IBM thinkpad r52 battery Thinkpad x22 battery IBM thinkpad t42 battery batteries, without any transformation equipment. Another advantage of NiMH batteries: nickel cadmium batteries greatly reduces the problem of "memory effect", which makes Ni-MH battery can be more convenient to use.
