The main performance indicators of rechargeable batteries
Safety performance indicators for battery failure is unacceptable. In which the greatest impact is the explosion and leakage. The occurrence of explosions and leakage mainly related to the battery internal pressure, structure and process design (such as valve failure to Acer LCBTP03003 Latitude D600 Battery Latitude D610 Battery, there is no lithium-ion battery protection circuit, etc.) and should be prohibited by the incorrect operation (for example, a battery into a fire) of the.
To AA 2300mAh Ni-MH rechargeable batteries, for example, indicates that the batteries 230mA (0.1C) charge 16 hours after 460mA (0.2C) discharge to 1.0V, the total discharge time of 5 hours, the release of electricity for the 2300mAh. Accordingly, if 230mA of current discharge, the discharge time is about 10 hours with 45Wh Apple PowerBook G4 Adapter.
Battery internal resistance refers to the current flowing through the Sony VGP-BPS12 battery when the subject of internal resistance. Charging the battery internal resistance is small between ibook g4 adapter and APple A1021 adapter, need to use special equipment can only be measured more accurate results. Generally known as the battery internal resistance is the charge-state resistance, meaning that the battery is fully charged when the resistance (corresponding to a discharge state of resistance, saying that after the battery fully discharge resistance by 65Wh Apple PowerBook G4 Adapter. Generally speaking, the discharge state of resistance Charge-state resistance than the large, and not very stable). The greater the battery internal resistance, the battery itself consumes energy more efficient use of the battery lower.
A great resistance when the battery charge is very severe fever to Sony PCGA-BP2NY battery PCGA-BP51 battery, so that the battery temperature is rising sharply. The impact on the battery and charger are all great. With the increase in the number of battery life, due to the consumption of electrolyte and battery internal chemical activity in the reduction of internal resistance of the battery will have different degrees of increase. The worse the quality of the battery up faster. Cycle life batteries that can be experienced repeated charge and discharge cycles to Dell Inspiron 510m Battery VGP-BPS9/B Sony VGP-BPS5. Battery life and capacity into the inverse relationship, the general Ni-MH battery cycle life of up to 500 times or more. High-capacity battery life is shorter, although up to 200 times or more. With the charge-discharge cycle life is also closely related to the conditions, generally the greater the charge current (faster charging), the shorter the cycle life.
Charge retention ability that is often talked about self-discharge, that means open-circuit state, the battery storage of electricity in certain environmental conditions to maintain the ability. Mainly by self-discharge battery materials, manufacturing processes, storage conditions, and many other factors with Sony VGP-BPS2 VGP-BPS9/S Dell Inspiron 1721 Battery. That the large current discharge capability. Digital cameras, power tools, electric toys, electric appliances in particular need to have excellent large current discharge performance of the battery. Large current discharge performance of primary and battery-related materials and production processes.
Usually the higher the temperature the greater the self-discharge rate. Rechargeable battery to a certain extent of self-discharge is normal to apple a1036 adapter or 45Wh Apple PowerBook G4 Adapter. With nickel-metal hydride batteries, for example, IEC standards require that the battery is fully charged after the temperature of 20 ± 5 ° C, humidity 65 ± 20% conditions, the open set aside 28 days, 0.2C discharge time of not less than 3 hours (ie, residual consumption is greater than 60%). Lithium-ion batteries and dry battery self-discharge is much smaller than Dell Latitude D620 Battery.
