Main article: Push start
A vehicle with a manual transmission may be push started. This requires caution while pushing the vehicle and may require the assistance of several persons. If the vehicle battery cannot provide power to the ignition system, push starting will be ineffective. Most vehicles with automatic transmissions cannot be started this way because the hydraulic torque converter in the transmission will not allow the engine to be driven by the wheels (some very old automatic transmissions, e.g., General Motors' two-speed Powerglide transmission, do leave a solid connection between the engine and wheels, and cars equipped with such transmissions can be push started). Future possibilities involve brake calipers of regenerative braking systems to embrace a jump-start when needed.
还有要注意的是应该后接负极(黑色的)要不然借正极时会有火花。
Car manuals recommend connecting the negative (black) cable last and disconnecting it first, since otherwise the battery may be shorted by the tool used to loosen the cable clamps. Connecting the positive (red) cable while the negative cable is connected can also cause a spark, resulting in battery explosion.<sup id="cite_ref-0" class="reference">[1]</sup>
