Usage
Use only with compatible Welch Allyn Green Series Portable Headlight systems (e.g. model 46070) as specified by the manufacturer.
Before replacing the battery, ensure the headlight system is switched off and disconnected from any external power supply or charger.
Open the designated battery compartment in the headlight or headband assembly as described in the device instructions for use.
Drop or slide the battery pack into the battery compartment or luminaire visor and plug into the corresponding connector, ensuring correct orientation and secure connection.
Close and secure the battery compartment according to the headlight’s instructions so that the pack is held firmly in place.
Recharge the battery using the specified Welch Allyn charger or direct power supply/charger intended for the 46070 headlight; do not use unapproved chargers.
Allow the battery to charge fully before first use and follow manufacturer guidance on charge cycles to optimise service life (approximately 2 years under normal use).
If the battery shows signs of damage (swelling, leakage, cracked housing) or fails to hold charge adequately, discontinue use and replace with a new OEM 72270 pack.
Dispose of depleted batteries via appropriate clinical or hazardous waste streams in accordance with local regulations for NiCd batteries; do not incinerate.
Contraindications
Not for use with non-compatible or non-Welch Allyn headlight systems or devices that do not specify use of the 72270 battery pack
Do not use if the battery housing is damaged, leaking or has been exposed to severe mechanical shock or liquid ingress
Do not attempt to open, modify or repair the battery pack
Do not use with chargers or power supplies other than those approved for the Welch Allyn 46070 Green Series Portable Headlight
Not intended for use in explosive atmospheres or environments where non-approved electrical equipment is prohibited
Adverse Effects
Improper use or charging with non-approved equipment may lead to overheating, leakage or reduced battery life
Physical damage to the battery pack may increase risk of electrolyte leakage or failure
In rare cases, failure of the battery may cause unexpected loss of illumination, potentially interrupting a procedure if no backup light source is available
Environmental harm may occur if NiCd batteries are discarded with general waste rather than via appropriate battery recycling or hazardous waste streams
Storage Conditions
Store in a cool, dry place away from direct sunlight and sources of heat
Avoid storage in environments with high humidity or condensation that could affect contacts or housing
Do not expose to open flame, excessive heat, or freezing conditions
Store away from metal objects that could short the terminals
Follow manufacturer recommendations for long-term storage of NiCd rechargeable batteries, including periodic charging if specified
