To purchase a new battery pack for your N2120 torch, you could check with local hardware stores or electrical supply stores. You could also try searching online retailers that specialize in lighting and electrical products, such as Amazon.
In New Zealand, you may also be able to find the battery pack you're looking for at major hardware retailers such as Bunnings Warehouse or Mitre 10. Additionally, you could try checking with manufacturers or suppliers of lighting equipment in the country.
If you are having trouble finding the exact battery pack you need, you could try reaching out to the manufacturer of the torch for assistance or to see if they have a recommended supplier in your area.

The Ryobi charger will flash green as it charges and then remain steady or slowly flashing green when fully charged. Flashing red means testing and if it remains steady or slowly flashing red it is defective.

Why are you telling us about a torch when this forum is for Cameras ?

What does indicator light mean?

• Steady red light: Battery is charging.
• Steady green light: Battery is fully charged.
• Flashing red light: Battery needs charging.
• Flashing green light: The music receiver is switched on.
• Flashing red/green light: The music receiver is available to be added to your phone.

A flashing red light indicates that there's an error, or the batteries are defective.

No, the unit won't switch itself off once the batteries have been fully charged. The unit will start trickle charging instead.
