Compatible Replacement for TND-740

This 3.7 V lithium-polymer battery fits the Rand McNally TND-740 truck GPS receiver. It replaces the original MLP454094 pack and restores portable operation for drivers who rely on the unit away from vehicle power. The black cell is brand new and built to OEM dimensions of 82.00 x 45.00 x 4.90 mm. Installation requires only basic tools and no soldering.

2200 mAh Capacity and Runtime

Rated at 2.2 Ah and 8.14 Wh, the pack delivers enough energy for typical route guidance sessions between charging stops. It comfortably handles several hours of screen-on navigation before needing a recharge. Runtime shortens noticeably when screen brightness is maximised or when the receiver searches for satellites in obstructed areas. The cell chemistry maintains stable voltage through most of the discharge curve.

Upgrade from Degraded Original Cells

This unit replaces a factory battery that no longer holds a useful charge after repeated charge cycles. The jump is worth it when the GPS shuts down unexpectedly or warns of low power within minutes of unplugging. It is not for the TND-740C model, which uses a different pack, nor for owners who only operate the device while permanently connected to a vehicle supply.
