[How To] BATTERY CALIBRATE

[TweetCode 15]

OPTIMAL USAGE OF LAPTOP BATTERY

If you are facing a problem with your battery pack and discharge time of battery is very less , follow these steps .

 

BATTERY PACK CALIBRATION PROCEDURE:

 

The battery pack calibration procedure helps users in optimal usage of a battery pack.

 

Calibration is the process of fully charging, discharging and then charging. It can take several hours.

 

A). Make sure that notebook power is turned off.

B). Connect the AC adapter to fully charge the battery pack.

C). After the battery pack is fully charged turn on the computer.

D).When the message “press F2 /del to enter into ---- “appears, pressF2/Del (i.e enter CMOS setup).

E).At this state disconnects the ac adapter and leaves the notebook/laptop on until the battery is fully discharged. (The notebook will shut down automatically. once battery is fully discharged)

F). Without switching on the notebook, connect the AC adapter and allow battery pack for 12 hour continuous charging.

 

Note: The above calibration process is recommended for 3 cycles generally during first time only. But our lab experience shows when the battery shows a poor backup time, usually it catches up to specs when we do the cycling for 3 times.

 

Tips:

 

 

1. Every deep discharge of the battery reduces the battery capacity.

2. It is recommended to disconnect the the laptop from ac power when the battery is fully charged. Continuing to charge a fully charged battery will lead to damaging the battery.

Sorry Mate, your TUT does not follow any rational with respect to the battery chemistry for laptop batteries. Also: when the battery is fully charged, the

computer reduces the current so that the battery pack stays just fully charged, enought to keep the battery from natural discharge.

 

You also say that deep discharge is not good for batteries (and I agree), so why does your rejuvination process involve up to three deep discharges?
