 > > We charged the unrecognized batteries using a 7.5 V - 230 mA DC power
 supply until they reached around 5.3 V. At this point the batteries were
 recognized by the laptopts, so we continued charging using laptops with
 firmware Q2B81. Now those batteries are working fine.

 > I followed the above procedure charging the battery until it reached 6.4
 V.  Firmware Q2B81, still doesn't recognise it (see the comment 03/26/07
 05:29:57), although the laptop can operate on it (until it drains it
 again, I presume).

 Problem resolved by reinitializing the battery EEPROM using batman.fth
 [http://wiki.laptop.org/go/Battery_Charging#EEPROM_Init].
