Systems and methods are provided for detecting low vehicle battery charge and responding appropriately to prevent complete vehicle battery drainage. One method includes: monitoring the charge of the vehicle battery; determining, by a telematics unit, that the charge of the vehicle battery has reached a low battery charge threshold while the vehicle engine is off; and providing, by the telematics unit, a notification to a telematics subscriber that the vehicle battery has low charge. Another method includes: monitoring the charge of the vehicle battery; determining, by a telematics unit, that the charge of the vehicle battery has reached a low battery charge threshold while the vehicle engine is off; and in response to determining that the low battery charge threshold has been reached, disabling at least one load draining the vehicle battery.
