GPS Battery for Rand McNally TND-740C

This lithium-polymer battery replaces the MLP454094 pack in the Rand McNally TND-740C navigator. It delivers 3.7V and 2000mAh capacity in a black 86.20 x 39.00 x 4.60 mm form factor. The cell is branded new and rated at 7.40Wh. It is not compatible with the base TND-740 model.

Voltage and Capacity Limits

The pack operates at a fixed 3.7V nominal voltage with a 2000mAh rating. It cannot supply higher voltages required by other Rand McNally units. The 7.40Wh energy capacity defines the maximum runtime between charges. Devices expecting a different cell chemistry or voltage will not function correctly with this pack.

Direct Replacement Installation

The battery fits the TND-740C battery compartment without modification. No soldering is required as the original connector mates directly. Common issues include inserting the pack into a non-C model TND-740, which shares a similar chassis but uses a different battery. Verify the device model number before fitting.

Questions about this item

Should I choose the 2000mAh version or a different capacity for my TND-740C?

The 2000mAh capacity is the exact specification for the MLP454094 part used in the TND-740C. No alternative capacity is offered for this model.

What does the 7.40Wh rating mean for daily GPS use?

The 7.40Wh rating at 3.7V delivers the rated 2000mAh, matching the original battery energy so runtime stays identical to the factory pack.

Does the connector follow a standard JST pitch or a proprietary layout?

The pack is built 100% OEM compatible for the MLP454094 part number, so its connector and pinout match the TND-740C board directly.
