Cameron & Co DS-CS-TM140SL GPS Battery

This lithium-ion cell delivers 3.7 volts and 950 milliampere-hours of capacity for compatible TomTom navigation units. It replaces the original 6027A0089521 battery and fits models such as the Go 50, Go 500, GO 600, One 140 and One 140S. The pack measures 47.00 by 34.00 by 5.50 millimetres and comes in black.

Sustained Operation Profile

The 3.52 watt-hour rating supports extended route guidance without the voltage sag seen in aged cells. Lithium-ion chemistry maintains a steady discharge curve across the usable range, so screen brightness and GPS acquisition remain consistent on long journeys. No memory effect means the battery can be topped up at any state of charge.

Upgrade Context

This unit restores full runtime to devices that now shut down early or refuse to hold a charge. It is not for users needing higher capacity than the original 950 mAh specification or for hardware that requires a different voltage or form factor. The jump is worth it when the factory battery no longer completes a typical day of navigation.

Questions about this item

How much heat does the 3.7V 950mAh lithium-ion cell produce during all-day navigation use?

The 3.52 Wh battery runs cool under normal GPS loads; no active cooling is required and the slim 5.50 mm profile fits the original battery cavity without extra thermal padding.

Which TomTom models and original part numbers must the device already use for this DS-CS-TM140SL to be a direct replacement?

It replaces TomTom part numbers 6027A0089521, AHA11110005, FMB0932008731, P2, VF65, VF6D and VF6S in the Go 50, Go 500, GO 600, One 140, One 140S and One 140S US units.

Will the 47.00 x 34.00 mm footprint align with the connector ribbon on an older One 140 unit?

Yes, the dimensions match the factory battery exactly, so the existing connector and retention clips engage without modification.
