1. An industrial truck comprising: (1) an exchangeable battery block including: (a) a first end, and(b) a second end opposite the first end; and(2) a battery case capable of accommodating the battery block, the battery case including: (a) at least one lateral access opening configured to permit slid
1. An industrial truck comprising: (1) an exchangeable battery block including: (a) a first end, and(b) a second end opposite the first end; and(2) a battery case capable of accommodating the battery block, the battery case including: (a) at least one lateral access opening configured to permit sliding of the battery block with the first end first into the battery case and pulling the battery block with the first end last out of the battery case, and(b) a battery case bottom having (i) a front edge section near the lateral access opening and (ii) an underside;(3) at least one independent roller or sliding member that, when the battery block is accommodated in the battery case, supports the battery block on the battery case bottom near the first end of the battery block;(4) a projection that, when the battery block is accommodated in the battery case, (a) projects (i) over the front edge section of the battery case bottom and (ii) over the underside of the battery case bottom downward and (b) is configured to be used as a lifting abutment for a battery transport device to lift the battery block and pull said battery block out of the battery case; and(5) a push frame that (a) carries the battery block, (b) is configured to be removed together with the battery block from the battery case or slid into the battery case together with the battery block and (c) includes (i) the at least one independent roller or sliding member and (ii) the projection. 2. The industrial truck of claim 1, wherein the at least one independent roller or sliding member includes at least two rollers for the battery block on the first end of the battery block with lateral distance relative to one another, and the battery case bottom has guide tracks for the rollers which run in a direction in which the battery block is inserted into the battery case. 3. The industrial truck of claim 2, wherein the guide tracks have guide profiles that are raised relative to the battery case bottom, and the rollers have circumferential concave guide grooves into which the guide profiles of the guide tracks engage when the battery block is slid into the battery case and when the battery block is pulled out of the battery case. 4. The industrial truck of claim 1, wherein the battery case has lateral guide elements for the battery block. 5. The industrial truck of claim 4, wherein the lateral guide elements comprise stationary rotatably mounted rollers. 6. The industrial truck of claim 1, wherein the battery block is capable of being removed from the push frame outside of the battery case. 7. The industrial truck of claim 1, wherein (i) the at least one independent roller or sliding member and (ii) the projection are arranged directly at a housing of the battery block. 8. The industrial truck of claim 1, wherein the projection is a slat that runs below the battery block and extends transversally to a direction in which the battery block slides when the battery block is being inserted into the battery case. 9. The industrial truck of claim 1, wherein the battery case has abutment means which stop the battery block when the battery block is pulled out of the battery case before the at least one independent roller or sliding member leaves the battery case bottom when rolling out, and the abutment means is capable of being overcome by further lifting and pulling the battery block out of the battery case. 10. The industrial truck of claim 1, further comprising an on-board mobile auxiliary device configured to lift the battery block in the battery case, pull the battery block out of the battery case and slide the battery block into the battery case. 11. The industrial truck of claim 1, wherein the industrial truck is a fork lift. 12. The industrial truck of claim 1, wherein the battery transport device is a fork lift device. 13. An industrial truck comprising: (1) an exchangeable battery block including: (a) a first end, and(b) a second end opposite the first end; and(2) a battery case capable of accommodating the battery block, the battery case including: (a) at least one lateral access opening configured to permit sliding of the battery block with the first end first into the battery case and pulling the battery block with the first end last out of the battery case, and(b) a battery case bottom having (i) a front edge section near the lateral access opening and (ii) an underside;(3) at least one independent roller or sliding member that, when the battery block is accommodated in the battery case, supports the battery block on the battery case bottom near the first end of the battery block; and(4) a projection that, when the battery block is accommodated in the battery case, (a) projects (i) over the front edge section of the battery case bottom and (ii) over the underside of the battery case bottom downward and (b) is configured to be used as a lifting abutment for a battery transport device to lift the battery block and pull said battery block out of the battery case;wherein, near the access opening, the battery case bottom has a recess including the front edge section of the battery case bottom so that the projection that forms the lifting abutment for the battery transport device projects through the recess downward past the underside of the battery case bottom when the battery block is in the battery case.
