<p>Battery Pack A battery pack features a shock-absorbing and sealed construction and an electronic control module (20) that provides automatic recovery circuitry (34, 36, 38) in 5 the event of a short circuit in the load whereby the power is terminated and then restarted at a lower level so that removal of the short circuit may be detected. Full power is restored to the load when the short circuit is removed. In addition, the electronic control module (20) of the battery pack uses the battery pack load, such as a cap lamp, to provide an indication of a low battery charge level (Fig. 6 - 152, 154, 156, 158). The electronic 1o control module (20) also provides a soft-start feature where the power provided to the bulb is ramped up to avoid current in-rush to the bulb during startup.
