Compatible Battery for TND-720 Truck GPS

This replacement battery fits the RAND McNally TND-720 truck GPS navigator. It is a lithium-polymer cell rated at 3.7V and 1.5Ah capacity. The unit suits drivers needing a direct swap for the original MLP643956 power pack.

Verify Device Model and Connector Match

Confirm your GPS is the TND-720 before ordering, as this pack is built for that specific model. Check that the existing battery carries the MLP643956 part number to ensure the connector and pin-out align. The physical size is 56.80 x 38.20 x 6.40 mm, so the battery bay must accept those dimensions.

Ready-to-Install Single Cell in Black

The package contains one black Li-Polymer cell with no extra cables, screws or software. Installation is a simple case swap once the old pack is removed. No firmware updates or calibration tools are supplied or required.

Questions about this item

Does the DS-CS-RMT720SL battery ship with any installation tools or adhesive strips?

The package contains one 3.7 V 1.5 Ah Li-Polymer cell measuring 56.80 x 38.20 x 6.40 mm; no tools or adhesive are included.

How do I confirm this 1500 mAh pack is the right capacity for my TND-720 instead of a higher-capacity alternative?

The original part MLP643956 is rated at 1500 mAh and 5.55 Wh, so this replacement matches the factory specification exactly.

What runtime can I expect from the 5.55 Wh rating during typical truck navigation use?

At 3.7 V the cell stores 5.55 Wh; actual operating hours depend on screen brightness, GPS polling rate and temperature, so a fixed figure cannot be given.
