What type of battery do RAM modules use?

RAM plug-in modules use small (“watch-style” coin-cell), non-rechargeable, lithium backup batteries (CMT part # ACC-PIM-BAT). These batteries supply power to the modules and allow them to maintain data storage when the NiCad system batteries are removed or fully drained. If the unit has shut down due to low power, it should be plugged into a wall outlet using a ACC-RE3B before being turned on. If the unit is turned on while it is unplugged, the backup batteries will be drained and data loss will occur.
