Battery Label Knowledge
The general contents of the label outside the battery pack are:
1. The Laptop battery manufacturer, model (batteries produced by regular manufacturers certainly have these two labels);
2. Types of batteries (sort based on the internal battery types);
Common used are Li-ion lithium-ion battery, Ni-MH battery, lithium-polymer battery, and rarely to see Ni-Cd (nickel-cadmium batteries) and the latest fuel cell.
3. Nominal Voltage;
General for 10.8V (11.1V) or 14.4V. Lithium-ion Dell KD476 battery, for example, we all know, the voltage of one lithium-ion battery is 3.6V, which of course can not reach the voltage notebook needed, so commonly used series approach. If the rated voltage is 10. V, it is a series of three, four series voltage becomes 14.4V, but some of the secondary battery in the factory calibration of single lithium-ion battery voltage is 3.7V, so the voltage to string three together is 11. 1V. If 1.2V Ni-MH battery, then use 9 single series to 10.8V, in order to achieve the laptop work required operating voltage.
4. Nominal Capacity;
In general, single Ni-MH hp PB991A battery capacity is larger than a lithium-ion battery, a 18650- Ni-MH battery capacity can achieved 4200 ~ 4500mAh, while the commonly used single 18650 lithium-ion battery capacity is 1500 ~ 2000mAh, so if laptop battery used Ni-MH batteries , only put the batteries in series to improve the battery voltage. The lithium-ion batteries are different for the battery manufacturer’s technological gaps, if the laptop battery use the lithium-ion batteries, commonly used three parallel to increase battery capacity, three parallel can be achieved in general 4500 ~ 6000mAh.
5. Battery Cautions:
Generally above the battery would be limited using environment label, using cautions, and toshiba PA3284U-1BRS battery recycling label.
