In the early years of Model T production, all Ts were started with a hand crank. A battery could be used to supply ignition current for starting, since it could be difficult to hand-crank a very cold engine fast enough for the magneto to produce sufficient current. However, although all T's had a "BAT" position ("battery") on the coil box switch and a corresponding terminal on the box, Ford did not supply or even encourage the use of a battery before 1919, when it introduced a battery-driven electric starter. Even this was not standard equipment for all models until sometime in 1926, the last year of production.
