Replacement Battery for Righton K-Plus 3

This 2600mAh lithium-ion pack replaces the original RT-121 cell in Righton K-Plus 3 and Retinomax 3 medical devices. It delivers 7.4 volts and 19.24 watt-hours through a fully decoded chip that communicates with the host exactly like the factory battery. The unit is new and certified to ISO9001, RoHS and CE standards.

Drop-in fit with decoded chip

The battery measures 71.70 by 37.60 by 20.40 millimetres and weighs 100.0 grams, matching the OEM footprint so no case modification or adapter is required. Its built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits, freeing the clinician from external safety hardware. Installation follows the same connector orientation as the original pack.

Capacity for extended clinical sessions

At 2600 milliampere-hours the cell powers a full day of typical retinoscopy and autorefraction workflows before needing a recharge. Runtime drops when the display brightness is maximised or continuous measurement mode is used for long periods. The pack reaches peak capacity after two or three complete charge-discharge cycles.

Questions about this item

How long does the 2600mAh capacity last during continuous medical-device use?

The 2600mAh lithium-ion cell delivers 19.24Wh at 7.4V; actual runtime depends on the instrument's power draw, and the pack reaches full performance after two or three complete charge cycles.

Does the battery generate noticeable heat or noise when powering a Righton K-Plus 3 all day?

The sealed lithium-ion unit has no moving parts, so it runs silently; normal warmth may appear under load, but the built-in protection circuitry prevents excessive temperature rise.

What charger connector must my Righton retinoscope already have for this pack to work?

The replacement uses the same decoded chip and connector layout as the original RT-121, so the device's existing charging port accepts it directly.
