Cameron & Co DS-CS-PHT600SL GPS Battery 3.7V 3200mAh Blue

Replacement battery for Phase II PHT6000

This lithium-ion cell replaces the original 3.7 V 3200 mAh pack used in Phase II PHT6000 and PHT6000-941 survey testers. It delivers 11.84 Wh of energy in a blue housing that matches the OEM form factor. The unit is supplied new and rated at 100 % OEM compatibility. Survey crews needing a direct swap for depleted stock batteries will find it fits without modification.

Steady discharge in field conditions

The 3.2 Ah capacity supports extended logging sessions where the instrument draws constant current over hours rather than short bursts. Lithium-ion chemistry maintains a stable voltage plateau through most of the cycle, so the tester’s reference circuits see minimal sag during long traverses. Self-discharge remains low between weekly jobs, reducing the need for top-up charges before each deployment. Heat buildup is modest because the cell operates well within its continuous current rating.

Hard limits of the 3.7 V platform

The fixed 3.7 V nominal voltage means the pack cannot power equipment that expects a higher rail, and the 11.84 Wh ceiling caps total runtime regardless of load management. Physical dimensions of 57.00 x 51.40 x 15.30 mm lock the battery into the original compartment, so devices with tighter cavities will not accept it. The single-cell design also prevents series or parallel stacking for voltage or capacity gains. Users needing longer endurance must carry spare cells rather than extend this one.
