Laptop battery "first three" charge
Second rumor: When a new DELL Inspiron 1500 Battery to buy back later, usually three times that the best charge and discharge cycles, and laptop battery charge and discharge time should be more than 12 hours, in order to activate the battery maximum effectiveness.
Truth: Ni-MH battery in order to achieve the perfect saturation, need to go through "complementary" and "trickle" process, this time is generally about 5 hours. At present, lithium-ion DELL FK890 Battery "constant", "constant" charge characteristics is to control the depth charge time 4 hours. Once filled, the internal battery will automatically stop charging protection circuit, so this is neither scientific nor practical significance.
Some people have been tested using a mobile phone. Charger with a travel charger in the battery is fully charged, switch to the battery cradle charger to confirm the degree of saturation, they think that the battery has not yet reached saturation. In fact, this lack of rigorous tests methods. The reason is that the indicator does not detect the cradle charger, saturated or not really the only standard reference voltage charger cradle the phone does not necessarily mean the reference voltage, so when the phone is that the DELL TM987 Battery reached, cradle charger may not think so, still charging, but is filling in, the only of its own know.
