3.6 V Ni-Cd medical battery for Welch Allyn devices

This 3.6 V nickel-cadmium pack delivers 750 mAh of rechargeable capacity in a single-unit format. It is built as a direct replacement for Welch Allyn 72300, 71000-A, 71000-C, 71020-A, 71020-C and 710171-501 devices used in clinical settings.

Voltage and chemistry constraints

The cell operates at 3.6 V nominal, which is lower than the 3.5 V label on some original packs but remains within the device tolerance. Nickel-cadmium chemistry means the pack will self-discharge faster than lithium types and can develop memory effect if repeatedly recharged from a partial state.

Installation notes

The pack fits the original battery compartment without modification and connects through the existing terminals. The main risk is reversed polarity during insertion; verify the orientation marks before seating the pack. Users who need a higher-capacity chemistry or a multi-pack configuration will not be served by this single Ni-Cd unit.

Questions about this item

How do I choose between the 3.5 V and 3.6 V versions for my Welch Allyn device?

The supplier lists 3.5 V in the title and 3.6 V in the specifications; both refer to the same 72300-08 pack, so select the single 1-pack option shown.

What does the 750 mAh capacity mean for daily use in a Welch Allyn 71000-A?

It indicates the charge the cell can deliver, so a device drawing roughly 75 mA would run for about ten hours before needing a recharge.

How does the Ni-Cd chemistry limit charging in a Welch Allyn 71020-C charger?

Ni-Cd cells require a dedicated constant-current charger; the Welch Allyn base station manages this, so use only the original cradle to avoid overcharge.
