Abstract
A power supply comprising a battery pack having a pair of batteries, one of the batteries being connected to power electrical equipment while the other battery is on standby, means for switching between the batteries when the charge in the battery connected to power the equipment falls below a predetermined level and/or the battery on standby is fully charged, means for uniquely identifying each of the batteries and charging means, said charging means including means for d istinguishing the individual batteries, the charging means being adapted to apply a charge cycle to the battery on standby, the charging means further including means to record the position in the charge cycle of the battery on standby, whereby if the battery pack is disconnected from the charging means, upon reconnection the charging means will resume charging of the battery on standby at the point in the charge cycle at which it was when the charging means was last disconnected.
