TP 700,720 - Low battery life when using the quick-charger
Applicable to: World-Wide
Service Information:
Low battery life may occur after charging battery FRU P/N66G2846 or P/N49G2166 with a quick charger, if the battery voltage is below 8 volts. The Quick Charger's charging cycle time is designed for a battery discharged to at or above 8 volts. A deeper discharge that results in battery voltage below 8 volts will require multiple charge cycles to completely charge the battery. Do NOT discharge between the Quick Charger cycles.
To prevent discharging the battery below the 8 volt range do the following :-
1. Charge the battery shortly after it has gone into a discharged suspend mode.
2. Do NOT attempt more then one resume operation after the discharge has occurred.
Follow normal problem determination if the battery discharge time is still short.
