Battery for Topcon GTS series

The Cameron & Co DS-CS-TOP600SL is a nickel-metal hydride replacement cell built for Topcon GTS-600, GTS-601, GTS-602 and GTS-605 total stations. It delivers 7.2 V and 2.7 Ah in the yellow housing that matches the original BT-50Q form factor. Survey crews needing a direct swap for depleted packs will find the dimensions of 93.60 x 69.20 x 55.10 mm identical to the factory unit.

Thermal and power behaviour

Ni-MH chemistry runs cool during the long stake-out sessions typical of construction layout work. Self-discharge is low enough to hold usable charge across weekly site visits without a maintenance top-up. The 19.44 Wh capacity supports a full day of angle and distance measurements on a single cycle. No active cooling or fan noise is involved because the cell operates passively inside the instrument.

Deciding specification

Capacity is 2700 mAh at 7.2 V; any instrument requiring a different voltage or a higher ampere-hour rating will not operate correctly with this pack. Buyers whose total stations specify a larger energy budget or a lithium-ion chemistry must select another part. The yellow colour code and exact case dimensions confirm mechanical fit for the listed GTS models only.

Questions about this item

How do I install the DS-CS-TOP600SL battery into a Topcon GTS-600, and what step is often missed?

Slide the 93.60 x 69.20 x 55.10 mm pack into the GTS-600 battery compartment until the latch clicks; the step often missed is ensuring the yellow housing sits flush so the contacts align with the 7.2 V rails.

What maintenance or replacement will the DS-CS-TOP600SL Ni-MH 2.7 Ah battery need later?

Expect to replace the pack when run-time drops below half of the original 19.44 Wh capacity; Ni-MH cells self-discharge, so top-up charge every 50 days if the GTS-601 or GTS-602 sits unused.

What limit appears first on the DS-CS-TOP600SL during sustained survey use?

The 2700 mAh capacity delivers roughly 19.44 Wh total; under continuous GTS-605 operation the voltage sag at 7.2 V becomes the limiting factor before the pack overheats.
