Replacement battery for Marco and Nidek keratometers

This Cameron & Co Ni-MH pack delivers 6 V and 2 Ah for the Marco MA-3010, KM-500BP1 and Nidek 02904 part numbers. It fits the KM500 and KM-500BPI auto keratometers used in clinical settings. The green casing matches the original equipment colour code.

Low self-discharge chemistry runs cool

Ni-MH cells generate minimal heat during the long duty cycles typical of keratometer operation. No active cooling is required and the pack adds negligible acoustic noise to the examination room. The 12 Wh rating keeps power draw well within the instrument's original design envelope.

Direct OEM fit eliminates adapter cables

The 48.72 x 34.20 x 44.20 mm form factor slides into the existing battery compartment without modification. One-to-one pin compatibility with part numbers B11304 and KM-500BPI means the device recognises the pack immediately. No extra chargers, configuration software or mounting hardware are supplied or needed.

Questions about this item

How do I fit the DS-CS-KRM500MD battery into the Marco KM-500 keratometer and what step is often missed?

Slide the pack into the compartment with the green label facing up, then press firmly until the latch clicks; the step most people miss is re-engaging the locking tab so the battery cannot shift during instrument movement.

What maintenance will this 6 V 2000 mAh Ni-MH pack need over its life?

Run a full charge-discharge cycle once per quarter to prevent memory effect, store at room temperature around 50 % charge if the keratometer will sit unused for weeks, and clean the contacts with a dry lint-free cloth whenever the cover is opened.

What runtime limit appears first during a full day of back-to-back patient exams?

The 12 Wh capacity typically delivers several hours of continuous operation; the practical limit is the keratometer's own power draw, so plan to recharge overnight once the low-battery indicator flashes.
