A battery protection unit for attachment to a vehicle battery, comprising first detection means (7) for detecting an unacceptable drop in the voltage of the battery, second detection means (8) for detecting that the vehicle has been involved in a collision, switch means (4) for isolating the battery completely or for isolating the battery from the starter motor of the vehicle, and override means (5) for overriding the switch means (4), the arrangement being such that the battery is isolated completely in the event that either the first detection means (7) detects that the battery voltage has dropped to an unacceptable level or that the second detection means (8) detects that the vehicle has been involved in a collision, and that the battery can be isolated from the starter motor of the vehicle in the absence of operation of the override means (5). |
