out repeatedly charge and discharge depth of the misunderstanding

    The laptop is equipped with the original hp pavilion dv1000 battery,hp pf723a, hp pm579a, hp pavilion dv4000 battery, after a period of time after use, there will inevitably be the case of standby time. Some users think: "depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life", I believe that this relatively one-sided.

    We must correctly understand the issue, may start using the laptop hp pavilion ze2000 battery, hp presario m2000 battery, hp presario v2000 battery, hp pavilion dv2000 battery types talking about. As we all know, in 1995, previously produced in the laptop, basically to use nickel-cadmium batteries to power. This battery, when used, if the charge-discharge mode is not correct, the battery will have a "memory effect",thereby reducing the battery's actual capacity, the elimination of this"memory effect" is the best way to repeatedly charge and discharge depth manner.With the emergence of nickel-hydrogen batteries, battery capacity has been significantly improved, but the "memory effect" did not completely eliminate the disadvantage. In recent years, lithium-ion hp ev088aa, hp 417066-001, hp f4486b, f4486a in the laptop has been rapidly increasing, largely because of lithium-ion batteries have been eliminated after the "memory effect" problem, it is used repeatedly to restore the depth of the battery charge and discharge performance of the method is not applied.But why lithium-ion battery capacity or the will to reduce the problem? Generate the root causes of this situation, are used in laptop and the original lithium-ion battery in the built-in battery management systems. Battery Management: At present in the laptop, almost all adopted the "hp cgr-b1870ae, bta0302001,hp pavilion zd7000 battery, hp pp2182d management" and "charge-discharge control" of two chip-level man
