Cameron & Co DS-CS-WB722MD 4.8V 3000mAh Ni-MH

This nickel-metal hydride pack supplies 4.8 volts and 3000 milliampere-hours for Welch-Allyn devices including models 12000 and 72240. It replaces original part numbers 7229 and B11261 with a direct-fit design. The green casing measures 90.00 by 45.80 by 22.60 millimetres. The unit is new and 100 percent OEM compatible.

Sustained load behaviour

Ni-MH chemistry delivers a steady voltage curve across the 14.40 watt-hour capacity, avoiding the sharp drop-off seen in short-burst tests. Internal resistance remains stable during extended discharge cycles typical of medical examination equipment. Self-discharge is low enough to keep the pack ready between daily shifts without constant top-up charging. No memory effect appears under normal partial-drain use.

Upgrade context

The pack replaces aging Ni-MH or Ni-Cd cells that no longer hold a full 3000 milliampere-hour charge in Welch-Allyn 12000 and 72240 handles. The jump is worth it when run-time falls below a full clinic day or when the original battery shows swelling or voltage sag under load. It is not for devices requiring a different voltage, connector pinout, or chemistry such as lithium-ion.
