Nickel-metal hydride batteries and lithium batteri

First,GHD Hair, the weight of
to the power cell voltage of every compartment point of view, are nickel-metal hydride and nickel cadmium 1.2V, meantime the lithium battery is absolutely as 3.6V,GHD IV Pink Straighteners, lithium battery voltage is 3 times the other two . And the weight of the same type of lithium battery and nickel cadmium batteries is virtually equal,GHD Red Butterfly 2011, meantime heavier than Ni- Ni-MH battery . We can look that the heaviness of each differ battery itself ,GHD Purple Gift Set, merely because of 3.6V lithium battery tall voltage, in the case of the output voltage equal to the number of medleys of unattached battery tin be depressed 1 third leaving later fashioning the battery heaviness and volume reduce.
Second, the memory achieve
nickel-metal hydride batteries and nickel-cadmium batteries have the same memory effect . Therefore, the normal discharge of management is also required. This periodic discharge management is being handled fuzzy state , or even the wisdom of some of the faulty behave discharge ( discharge or use a few times each time after the discharge is deserving to the company's alter ) This ponderous discharge management In the use of nickel-metal hydride batteries can not be avoided . In terms of relative lithium batteries because not memory effect,GHD Diamond Flag 2011, in the use of a quite handy and easy. It is entirely without regard to the number of residual voltage , can be instantly charged , the charging time ambition surely be reduced.
Third, self-discharge rate
nickel-cadmium batteries for 15 to 30 % ( January). Ni-MH battery for 25 ~ 35% (month ), lithium 2 to 5 % ( January). More self-discharge NiMH batteries was the largest, the other two types of lithium battery expertise and low discharge rate in comparison .
four , charging
nickel-metal hydride batteries and lithium batteries
no resistant to overcharge . Therefore, the nickel-metal hydride batteries to charge PICK CUT constant present control mode when the charging voltage approaches the maximum , to stop the charging of the charge as the best course . And lithium use constant present ,GHD Green Butterfly 2011, constant voltage charging mode the best, whether nickel-cadmium battery charger as charging -DV , then control of the nickel-metal hydride batteries and lithium batteries.
