With ongoing cost-of-living pressures, some families struggled to afford batteries.
“They can’t afford to spend $12 to $13 on batteries,” said Phyllis Latu from socal housing provider Maranga Fanau.
“The unopened packs of batteries are now being diverted from landfill and reused in the community, donated to South Auckland charities,” the airport said.
Most of the donated batteries are AA and AAA.
Fred Stein, Civil Aviation Authority deputy chief executive for aviation security, said power banks, AirPods and vapes must go in carry-on luggage.
“We don’t want to be taking people’s batteries from their checked-in bags but batteries can be dangerous because they can overheat and catch fire.”
The airport said the donation programme started in August last year.
And since then, about 95,000 batteries had been donated.
“They are mainly used by charities for toys, smoke alarms, and by schools for education purposes.”
Batteries comprised 70% of all items AvSec confiscated.
The airport advised travellers to pack batteries, power banks and wireless ear buds in carry-on luggage to avoid those items being confiscated.
Loose batteries must have the terminals covered, such as with tape.
“You can take up to 20 spare batteries on your trip,” the airport said.
Some airlines have in recent months tightened rules after a power bank in the overhead compartment was blamed for causing a fire on Air Busan Flight 391 in January this year.
In that flight from Busan in South Korea to Hong Kong, 27 people were injured.
