Zusammenfassung:	A battery backup system for a mobile telematic system comprises a main power input (10), arranged to provide power to the mobile telematic system (14), a first battery (16'), arranged to provide a first battery input, and means (12) for monitoring the main power input (10) and, when the main power input falls below a first predetermined value, causing the first battery (16') input to provide power to the mobile telematic system (14). The system further comprises a second battery (16"), arranged to provide a second battery input, and means (19) for monitoring the first and second battery inputs and, when the first battery input falls below a second predetermined value, causing the second battery (16") to provide power to the mobile telematic system and, when the second battery input falls below a third predetermined value, causing the remainder of the first battery (16') to provide power to the mobile telematic system. The first battery (16') is a rechargeable battery and the second battery (16") other one is non-rechargeable.
