4 x AA rechargeable batteries and wall charger for $17. Charger will fit AA or AAA batteries. $6 delivery or pickup from store for free. I know you can get weird brands off Trade Me for cheaper and Varta batteries from AliExpress for next to nothing, but I've had bad experiences with buying cheap rechargeable batteries from overseas, too many dodgy fakes, so wanted to get a known brand from a NZ retail store and this was the best deal I came across. The 4 batteries by themselves are $22.85 at Bunnings.
