6.5.3 Cell Removal and Stack Disassembly
If a requirement to disassemble a module stack arises, it is recommended to remove the cells before
disassembly. Once the battery string has been removed from service, the technician must use
properly insulated tools and all appropriate battery safety methods. If removing cells from a new
system in preparation for installation, skip to step 5.
1. Remove the faceplate from the subject module.
2. Disconnect the system ground connection.
3. For each connector attached to the cell, loosen (but do not remove) the terminal bolts at either end.
4. While holding the connector in one hand, remove the terminal bolts completely. Remove the connector
and set aside. Repeat for other connectors.
5. After performing the electrical preparation described above, the steps to physically remove the cell or
cells can be performed as follows: Starting with the top module, loosen cell side restraint plate bolts
until cell side restraint plate is loose. Do not remove bolts completely. For systems with Cam
assemblies, see Appendix B.
6. Remove front cell restraint bar bolts, shown in Figure 6-4. Restraint bar may be left attached to
modules using retaining rings to prevent it from being misplaced. The cell side restraint plates
can now be removed. This will allow the cells to be moved apart for ease of removing the cell
spacer plates and the cells. The cell spacer plates can now be removed.
7. Attach the “cell puller tool”, part number RE03197. This tool, shown in Figure 6-6, is available from
your local C&D TECHNOLOGIES representative.
8. Prepare for cell removal by moving an insulated platform lift or equivalent lifting apparatus in proximity to
the bottom of the stack module from which the cell is to be removed as shown in Figure 6-8. Make
sure all exposed metal on the platform is insulated. Verify the capacity of the lifting apparatus is
sufficient to safely lift the cell. Before removing the cell, note the orientation of the cell in the
module, i.e., positive terminal up or down.
9. Pull the cell straight out onto the platform, shown in Figures 6-7 and 6-8.
10. Store removed cell for re-installation or disposal.
11. Repeat steps 6-10 for all cells within a module before removing a module from the stack
12. Disassemble the stack modules by removing module-to-module bolts.
13. For re-installation of modules and cells, refer to sections 6.5.1 and 6.5.2
Note: msEndur II cells should never be lifted by the terminals.
Do not use the cell puller tool as a lifting device.
