DOCUMENTATION AND OTHER VENDOR REQUIREMENTS FOR BUTTON BATTERIES

OTHER MANDATORY REQUIREMENTS:

BUTTON CELL
Requirements for products that contain button (coin) cells 32mm and under (in particular, remote controls).

GENERAL: 
• All consumer products that incorporate button batteries must have measures incorporated to prevent young children from accessing the batteries as per section 4.8 of AS/NZS 62368.1:2018: "Products containing lithium coin/button cell batteries" 
• Coin/button batteries bundled with products or offered for sale as standalone items must be supplied in child-resistant packaging. Typically this will mean the batteries are individually sealed in tough plastic envelopes, and that assembly(ies) then sealed in another, separate, layer of tough plastic (which will typically be the retail presentation pack). Both layers of plastic must require the use of cutting tools to open. 
Simple "dime store" blister packs where all the batteries can fall out at once are now illegal.
• All such products must also carry appropriate warnings.

EXEMPTIONS:
• Soldered-in batteries 
• Removeable batteries that require substantial disassembly of the product (eg computer backup) 
• Equipment designed for locations where it is unlikely that children will be present
• Professional equipment not normally available for retail sale. Note: Anything sold in a retail environment (Jaycar, Harvey Norman etc), regardless of purpose, is automatically excluded from this category.

REQUIREMENTS FOR PRODUCTS WITH USER-ACCESSIBLE BATTERY COMPARTMENTS (IN PARTICULAR REMOTE CONTROLS THAT USE COIN CELLS):
The battery compartment must be so designed as to make it unlikely that young children would be able to remove the cover. 
Acceptable methods are:
• A cover using a captive metal screw that requires a standard  screwdriver (typically Phillips) to open.
This must pass safety saftey testing as outlined in 4.8.4.3 "Battery replacement test" of AS/NZS 62368.1:2018.
This involves removing and replacing the screw 10 times, using a torque screwdriver set to the tension specified. After ten removals and replacements, the screw must still be able to be tightened to the specified torque. In other words, the plastic must not start to disintegrate so that it is no longer capable of holding the screw.
• A cover that has two separate locking mechanisms that have to be simultaneously operated to open
• A slotted cover that requires the use of a coin or similar object to open, and requires 90 degrees or more of rotation.

Ideally, the battery compartment would be designed so that the presence of the cover is required to hold one of the battery contacts against the battery, preventing operation unless the cover is re-fitted.
