Cameron & Co DS-CS-RTK300MD 7.4V 2600mAh 19.24Wh video accessory

Cameron & Co DS-CS-RTK300MD replacement battery

This lithium-ion pack is built for the Righton K-Plus 3 and Retinomax 3 instruments. It delivers a 7.4 V, 2.6 Ah capacity in a compact black housing. The cell is supplied new and matches the original RT-121 part number. Medical technicians and field operators who rely on these specific devices will find it a direct fit.

Practical limits of the 7.4 V lithium-ion interface

The pack provides 19.24 Wh of energy at its nominal voltage. Runtime scales with the instrument’s current draw, so heavier workloads will deplete the charge faster. No onboard fuel gauge or balance connector is present, so remaining capacity must be judged by the host device. The fixed 71.70 x 37.60 x 20.40 mm form factor prevents use in any other equipment.

Capacity and headroom for clinical sessions

A 2600 mAh rating supports extended examinations on a single charge under typical usage patterns. The 19.24 Wh reserve handles continuous operation until the host signals low power. Users needing longer uninterrupted runtimes or hot-swap capability will require additional packs. The single-cell design offers no redundancy if the cell fails during a procedure.
