Compatible Dell Controller Battery

This replacement battery fits Dell SC7020, SC5020 and 3020 controller units. It matches part numbers JVR23, 0JVR23, 03-55753-301 and 31NR19/66-2. The unit is supplied new and ready to install.

10.8 V Lithium-Ion Chemistry

The cell operates at 10.8 V using lithium-ion chemistry. Voltage and chemistry together determine whether the battery will communicate correctly with the controller's charging circuit. A mismatched voltage or chemistry will prevent the system from recognising the pack.

38.88 Wh Capacity for Controller Uptime

At 38.88 Wh the pack provides enough reserve for typical controller cache-flush and shutdown routines. It is not sized to run the controller indefinitely during extended power loss. Buyers needing longer hold-up time should look for a higher-capacity alternative.

Questions about this item

How long will the 38.88Wh capacity keep a Dell SC7020 controller running?

The 38.88Wh lithium-ion pack is rated at 3600mAh and 10.8V, matching the original JVR23 specification for the SC7020, SC5020 and 3020 controllers.

Does the 10.8V rating limit which Dell controller models this battery can replace?

The 10.8V output is the exact voltage used by the Dell SC7020, SC5020 and 3020 controller modules, so it fits those systems without any voltage mismatch.

Will the 03-55753-301 battery fit the SC5020 controller bay without modification?

This replacement is built to the JVR23 / 31NR19-66-2 form factor, so it slots directly into the SC5020, SC7020 and 3020 controller battery compartments.
