These AA and AAA batteries recharge by USB-C

I have a bag in my garage where I place dead single use batteries. I don't use a lot of AA or AAA batteries, but when they die out, I collect them knowing that one day, when that bag is a bit fuller, I'll take them to be recycled.

But the ReChargeCore batteries from Aussie company Laser are a better idea. Rated to last up to 1,000 recharges via a USB-C port on the top of the battery, the Lithium Ion ReChargeCore batteries cost just $29.95 for a four-pack, which works out at about $7.50 per battery.

That's pretty good value. Doing the math quickly – Amazon is offering a 30 pack of Energizer Max AA batteries for $23 at the moment (though price may change). That works out at 77 cents a pop.

If the ReChargeCore can be recharged 1000 times and there's four in the pack, that means you're effectively getting the equivalent of 4,000 batteries for $29.95. That would work out at $0.0075 per battery. You need to throw in a bit of cost for the electricity to recharge, but it's still going to work out much cheaper.

Then there's the reduced waste. Laser reckons the ReChargeCore batteries save up to 15.9kg of landfill.

You can recharge the batteries in just 90 minutes over USB-C, so you never really have to go without power for too long.

Pricing and availability

The ReChargeCore batteries are available in both AA and AAA sizes, with 4-packs of each available exclusively through Harvey Norman for $29.95.
