Quck Test Battery

Quick Test the battery(Pavilion DV6000) has a secret lies,To a large extent,you should understand how the battery is being loaded.Different short-circuit the battery load current pulse. EV088AA laptop has long and fluctuating loads, and has the power tool about intermittent heavy.


Because of these differences in loads, a battery for a digital mobile phone should be tested primarily for low impedance to assure a clean delivery of the current bursts, whereas a battery for a notebook should be examined mainly for the bulk in energy reserve. Ultra-low impedance is of less importance here. A battery for a power tool, on the other hand, needs both — low impedance and good power reserve.Some quick testers simulate the equipment load and observe the voltage signature of the (417066-001) battery under these conditions. The readings are compared with the reference settings, which are stored in the tester. The resulting discrepancies are calculated against the anticipated or ideal settings and displayed as the SoH readings.

The first step in obtaining quick test readings is measuring the battery’s internal resistance, often referred to as impedance. Internal resistance measurements take only a few seconds to complete and provide a reasonably accurate indication of the battery’s condition, especially if a reference reading from a good battery HP Pavilion DV2000 is available for comparison.Unfortunately, the impedance measurement alone provides only a rough sketch of the battery’s performance. The readings are affected by various battery conditions, which cannot always be controlled. For example, a fully charged Presario V6000 battery that has just been removed from the charger shows a higher impedance reading than one that has rested for a few?hours after charge. The elevated impedance is due to the increased interfacial resistance present after charging. Allowing the battery to rest for an?hour or two will normalize the battery. Temperature also affects the readings. In addition, the chemistry, the number of cells connected in series and the rating of a battery influence the results. Many batteries(Presario V6000) also contain a protection circuit that further distorts the readings.
