Checking the Battery Pack (2625 365X, XD)



Checking the Battery Pack

Battery charging will not start until the Fuel-Gauge shows that less than 95% of the total power remains, with this condition the battery pack will charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life.

Do the following:
  1.  Power off the computer.
  2.  Remove the battery pack and measure the voltage between battery  terminals 2 (+) and 6 (-).

     

    Terminal Voltage (Vdc) / Signal
    1 -
    2 +8 to +13.5
    3 -
    4 -
    5 Thermal
    6 Ground (-)

     

    NOTE: Signal lines, not used in these steps,  are used for communication between the system and the battery.

  3.  If the voltage is less than  +9.6 V dc, the battery pack has  been discharged. Recharge the battery pack.

     If the voltage is still less than +9.6 V dc after recharging,  replace the battery.

    NOTE:  If the voltage of the battery pack is 0 V, it is not defective.

  4.  If the voltage is more than +9.6 V dc,  measure the resistance between  battery terminals 5 and 6.  The resistance must be 4 K to 30 K ohm.

     If the resistance is not correct, replace the battery pack.
     If the resistance is correct, replace the system board.
