The elevator car includes an elevator car panel and a battery pocket positioned in the elevator car panel. A battery is removably positioned in the battery pocket. The battery and the battery pocket are configured such that inspection, maintenance and/or repair of the battery is performed without entry into the hoistway of the elevator system. A method of servicing an elevator system includes driving an elevator car along a hoistway and stopping the elevator car near a selected elevator landing floor. A battery is at least partially removed from a battery pocket at the elevator car via a technician located at the selected elevator landing floor for inspection, maintenance, replacement and/or repair. ## Claims ### Claim 1 An elevator car for an elevator system comprising: an elevator car panel; at least one battery pocket disposed in the elevator car panel; and at least one battery removably positioned in the at least one battery pocket, configured such that one or more of inspection, maintenance, replacement or repair of the at least one battery may be performed without entry into a hoistway and the elevator car of the elevator system. ### Claim 2 (depends on 1) The elevator car of claim 1, wherein the at least one battery pocket is disposed at a floor panel of the elevator car. ### Claim 3 (depends on 1) The elevator car of claim 1, wherein multiple batteries are disposed at the elevator car panel. ### Claim 4 (depends on 1) The elevator car of claim 1, wherein the at least one battery supplies electrical power to the elevator car. ### Claim 5 (depends on 4) The elevator car of claim 4, wherein the electrical power is for one or more of elevator car drive, lighting or control systems. ### Claim 6 An elevator system comprising: a hoistway; and an elevator car suspended in the hoistway via a suspension member and drivable along the hoistway, the elevator car including: an elevator car panel; at least one battery pocket disposed in the elevator car panel; and at least one battery removably positioned in the at least one battery pocket, configured such that one or more of inspection, maintenance, replacement or repair of the at least one battery may be performed without entry into the hoistway and the elevator of the elevator system. ### Claim 7 (depends on 6) The elevator system of claim 6, wherein the at least one battery pocket is disposed at a floor panel of the elevator car. ### Claim 8 (depends on 6) The elevator system of claim 6, wherein the at least one battery is removable from the at least one battery pocket by a technician at a landing floor of the elevator system. ### Claim 9 (depends on 6) The elevator system of claim 6, further comprising a handle disposed at the at least one battery for removal of the at least one battery from the at least one battery pocket. ### Claim 10 (depends on 6) The elevator system of claim 6, wherein multiple batteries are disposed at the elevator car panel. ### Claim 11 (depends on 6) The elevator system of claim 6, wherein the at least one battery supplies electrical power to the elevator car. ### Claim 12 (depends on 11) The elevator system of claim 11, wherein the electrical power is for elevator car lighting, drive and/or control systems. ### Claim 13 A method of servicing an elevator system comprising: driving an elevator car along a hoistway; stopping the elevator car near a selected elevator landing floor; and at least partially removing at least one battery from at least one battery pocket at the elevator car via a technician located at the selected elevator landing floor without entry into the hoistway and the elevator car for one or more of inspection, maintenance, replacement or repair. ### Claim 14 (depends on 13) The method of claim 13, further comprising: stopping the elevator car a distance above the selected elevator landing floor; and at least partially removing the at least one battery from the at least one battery pocket disposed at a floor panel of the elevator car for one or more of inspection, maintenance, replacement or repair. ### Claim 15 (depends on 13) The method of claim 13, wherein the at least one battery supplies electrical power to the elevator car for one or more of lighting, drive or control systems.
