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.

  • 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.

Onset

Immediate, once installed in a compatible handle and adequately charged.
