Usage

Only trained personnel or clinicians familiar with Welch Allyn 3.5 V handles should replace the battery.
Ensure the handle is disconnected from mains power and any charging source before battery replacement.
Unscrew and open the handle according to the Welch Allyn instructions for use to access the internal battery compartment.
Remove the existing 3.5 V rechargeable battery, noting its orientation inside the handle.
Insert the new 72300 battery into the handle in the correct orientation, ensuring good contact with internal terminals.
Reassemble and securely tighten the handle components.
Place the handle on the appropriate Welch Allyn charger (wall transformer or desk charger compatible with 3.5 V handles) and allow the battery to fully charge before first use.
After charging, test the handle with the connected instrument (otoscope, ophthalmoscope, etc.) to confirm normal illumination and operation.
Follow Welch Allyn’s guidance on charging cycles to maximise battery life (e.g. avoid prolonged continuous overcharging beyond manufacturer recommendations).
Do not attempt to open or modify the battery pack; it is not user-serviceable beyond normal installation and removal.

Contraindications

Do not use this battery in devices that are not specified as compatible with Welch Allyn 3.5 V NiCd handle batteries (e.g. devices requiring different voltage, chemistry or size).
Not suitable for use in non-rechargeable (primary cell) handles or in handles designed for lithium-ion battery packs.
Do not install or use the battery if the casing is damaged, cracked, swollen or shows signs of leakage.
Avoid use in environments where exposure to excessive heat, open flame or strong oxidising chemicals is possible.
Use only with approved Welch Allyn chargers intended for 3.5 V NiCd rechargeable handles; using incompatible chargers can cause overheating or reduced battery life.

Adverse Effects

If the battery is damaged and electrolyte leaks, contact with skin or eyes may cause irritation or chemical burns; flush with plenty of water and seek medical attention.
Incorrect charging or short-circuiting can cause the battery to overheat, potentially leading to burns, fire or venting of gases.
Improper disposal of NiCd batteries can contribute to environmental contamination due to cadmium content.
A failing or inadequately charged battery may result in dim illumination or sudden power loss during examination, which could interfere with clinical assessments; routine checks of charge status are recommended.

Storage Conditions

Store unused batteries in their original packaging in a cool, dry, well-ventilated environment.
Avoid storage in high-temperature locations, direct sunlight or near heat sources, as excessive heat can shorten battery life.
Keep away from moisture, corrosive vapours and conductive materials that could bridge the terminals.
For long-term storage, follow general NiCd recommendations: moderate temperature, partial charge, and periodic top-up charging where practical, in line with institutional policy.
Do not store batteries loose where they may contact metal objects and short-circuit.
Keep out of reach of children and unauthorised personnel.
