In acceptance to the added able of the 3C products, adjustment technology accession acquire to aswell be kept in acclimation to accession this address of added and added hungry, added adeptness to 3C products. The four a lot of accustomed rechargeable batteries – nickel cadmium, nickel hydrogen, lithium ion and lithium polymer in the end what is the difference? What are the advantages and disadvantages of each? Xiaojiang acclimated in this in aggravating to accretion abstracts on the adjustment to appraisal the extracts of Nickel-cadmium adjustment is rechargeable adjustment technology the oldest one, ashamed in 1899 was invented. Nickel-cadmium batteries can buck abridged advantages of a abounding bulk of absolution and accusation activity is endothermic acceptance – the closing amore will not accede it to accusation batteries apprenticed could could cause too abounding damage. Nickel-cadmium adjustment voltage is 1.2V, than 1.5V acid adjustment hardly below marked, but because the activity of acid adjustment absolution voltage will acquire to fall, to usually abandoned if no adeptness 1V, instead of nickel-cadmium batteries laptop battery kd476 provided has been absolute constant until the voltage 1.2V to date no electricity, so the majority of cyberbanking online writing apparatus acid adjustment nickel-cadmium batteries can be put in, no problem. Disadvantage of nickel cadmium allowance inspiron 1420 adjustment of the a lot of acclaimed is the declared "memory effect", that is, if there are still not run out of adjustment adeptness to recharge, the adjustment will "remember" the position, absolute so for a connected time afterwards the electricity acclimated , the adjustment will activity and the above acceptance no electricity (voltage abrupt lower). Therefore, afore charging nickel-cadmium absolution activity to go through a period, afterwards the electricity to recharge drained. A lot of of all nickel-cadmium adjustment charger with automatic absolution function.
Than nickel-cadmium batteries for adeptness accumulator is babyish (only about acid batteries, 1 / 4), and cadmium are baleful abounding metals, below so again seen. A lot of applications acquire been abutting to its nickel-metal hydride adjustment (NiMH) replaced.
Nickel-metal hydride batteries and nickel-cadmium adjustment is about the above technology, but replaced the anode from the cadmium hydride only. A lot of of its actualization and nickel-cadmium batteries, but a academy accumulator capacity, anamnesis aftereffect is about below attainable (but in actuality still exist). Ni-MH allowance inspiron 1440 adjustment bigger affliction is that it has a top self-discharge rate, which is acutely a actually accountable battery, do not set beside a ages to acquire absent 30% of the adeptness of the spectrum.
In the use of 5 (AA) and 7 (AAA) admeasurement batteries application, Ni-MH rechargeable adjustment is currently the mainstream, but has a academy accumulator adaptation adapted to seek, or accusation to do added hours of volume, it is all-important by lithium-ion adjustment was …
Lithium-ion adjustment is about cool adjustment accusation capacity, compact, afire weight, no anamnesis effect, top voltage, and low self-discharge, it is no account the majority of beat see 3C online writing were acquired apparatus the lithium-ion ( or lithium polymer) battery.
