A method of boosting a vehicle battery includes supplying a current to the battery, detecting an engine crank event, and, upon detecting the engine crank event, dynamically adjusting (i.e., first substantially increasing, and then decreasing) the current in response to battery voltage. The method may also include verifying a crank-ready condition in the battery by comparing one or more of battery voltage, battery current, and battery charge accumulation to respective crank thresholds. In certain embodiments, this verification step occurs only after a minimum charging time has elapsed, and may time out after a maximum charging time. Once the crank ready condition is detected, the operator may be so signaled. At the conclusion of the boost and crank cycle, the current to the battery may be interrupted and the engine status-started or not started-may be detected. The battery may also be monitored for error conditions.
