Rechargeable Battery for Diagnostic Handles

Description

This 3.5 V Lithium-Ion Rechargeable Battery is a genuine Welch Allyn replacement battery (part 71960) for selected 3.5 V Lithium Ion power handles. The \Over Engraved\ version sold by Medisave is a clearance item where the casing has been laser-engraved in error; this cosmetic engraving does not affect the battery’s performance or functionality. It delivers reliable lithium-ion power for Welch Allyn diagnostic instrument handles while being lighter and longer-lasting than traditional NiCad batteries.

Usage

Ensure the battery is the correct model (71960) for your Welch Allyn 3.5 V lithium-ion handle before use.
Insert the battery into the compatible Welch Allyn handle (e.g. 71900 series) following the handle’s user manual, observing correct orientation and ensuring contacts engage properly.
Charge the handle with the installed battery using an appropriate Welch Allyn charger (e.g. universal desk charger or USB charging module designed for lithium-ion handles).
Before first clinical use, fully charge the battery according to the handle/charger instructions.
Do not attempt to open, modify, puncture or disassemble the battery module.
Only use with compatible Welch Allyn equipment; do not use this lithium-ion battery in NiCad-only handles or non-approved devices.
If the battery or handle becomes excessively hot, emits an unusual smell, or shows signs of damage, remove it from service and follow facility protocols for inspection and disposal.
Follow local and institutional policies for safe handling, charging and storage of lithium-ion batteries.
Refer to the Welch Allyn handle’s Instructions for Use for detailed operating and charging guidance.

Contraindications

Do not use this battery in non-compatible handles or devices, particularly those not designed for lithium-ion batteries.
Do not use if the battery casing is cracked, swollen, leaking or otherwise visibly damaged.
Do not expose the battery to fire, excessive heat, crushing forces or immersion in liquid.
Not intended for use outside of approved medical/clinical diagnostic equipment.
Do not short-circuit the terminals or store the battery with conductive objects across the contacts.
Should not be handled or charged by untrained personnel without appropriate supervision and instructions.

Adverse Effects

If misused, damaged or short-circuited, lithium-ion batteries can overheat, leak, vent or, in extreme cases, catch fire.
Improper handling can result in burns, electric shock or chemical exposure from leaking electrolyte.
Defective or failing batteries may cause intermittent power loss to diagnostic instruments, potentially interrupting examinations.
Overcharging or using non-approved chargers can shorten battery life and increase the risk of overheating or failure.

Storage Conditions

Store in a cool, dry environment away from direct sunlight and heat sources.
Avoid temperatures outside the range recommended in Welch Allyn documentation (typically around 10–30 °C for storage).
Do not freeze the battery or expose it to high humidity or condensation.
When not in regular use, store the battery partially charged and recharge periodically in line with manufacturer guidance to preserve capacity.
Keep away from metal objects that could short the terminals.
Store out of reach of children and non-authorised personnel.
Follow local regulations and recycling programmes for end-of-life lithium-ion medical batteries; do not dispose of in general waste.

Duration

When installed in a compatible Welch Allyn 3.5 V lithium-ion handle, a fully charged battery typically provides up to approximately 120 minutes of on-time under normal operating conditions; actual runtime depends on instrument head type, light source and usage pattern.
