A battery changing system in combination with a battery holder is provided. The battery changing system comprises a mobile frame, and a battery lift assembly including a pair of lifting arms forming an opening for receiving the battery holder. Mounting structure movably connects battery lift assembly to the mobile frame. Actuating structure moves the battery lift assembly between an initial position and an operative position wherein the battery holder is raised to a selected elevation above the ground. Elongated releasably lockable safety retaining structure is attached to the battery lift assembly. The battery holder is constructed and arranged to be received in the opening and includes first engaging structure. Each of the lifting arms includes an upwardly facing engaging surface. The upwardly facing engaging surfaces are positioned and configured such that upward movement of the battery lift assembly towards the operative position thereof causes the upwardly facing engaging surfaces of each lifting arm to engage the first engaging structure. The releasably lockable safety retaining structure is constructed and arranged to be releasably locked with the battery holder so as to extend forwardly from the battery lift assembly to the battery holder when the battery lift assembly is in the operative position thereof to thereby safely secure the battery holder to the battery lift assembly so that the battery holder is prevented from moving forwardly in the event that the mobile frame is violently jarred while moving forwardly down a sloped surface such that the battery holder is moved upwardly with respect to the lifting arms and the first engaging structure is moved out of engagement with the upwardly facing engaging surfaces.
