8xAA, 4x AAA plus A charger. Plenty of stock available. Seems like a deal to me, finally got on the eneloop bandwagon.
Obviously membership required
Unless something has changed a bit of warning, the charge is slow and sucks…
Read the fine print on the front, it says "Charging time approx 10 hours (AA4cells)". That means the charger in this pack is a "dumb" charger.
If you want the batteries to last more than 10-20 charge cycles, don't ever use this charger, get a smart charger and use that. Even one charge with this charger is likely to irreparably damage the batteries you charge.
Think of this as a batteries-only deal. Even without the charger, it's a pretty good price for 12 eneloop batteries (8xAA, 4xAAA).
Any smart charger recommendations?
Got this one recently. its pretty good:
if you're after something easy-to-use and inexpensive, the Liitokala Lii-202 is good. It is pretty cheap (about US$10.50 shipped) at Fasttech, but it only charges two batteries at a time, and it doesn't come with a mains adaptor, you have to power it from a phone charger or a PC (standard full-size USB-A plug).
Note that the Lii-202 only charges 1 or 2 batteries at a time. If you want to charge 3 or 4 at a time there is the Lii-402 model, but I don't recommend that one, as it halves the charge current, which makes charging too slow for reliable end-of-charge detection. Instead, buy a second Lii-202, assuming that you have a second phone charger, or your phone charger has two or more USB-A sockets.
For a full-featured charger, which comes with a mains adaptor and will tell you how much current went into each battery during the charge, and also has test modes, I recommend the Liitokala Lii-500, Lii-500S or Lii-600. Test modes and the readout of how much power went into each battery will let you know when a battery is starting to fail, so you can weed out the bad battery and continue to use the other batteries. These chargers cost a fair bit more than the Lii-202, but are on special every now and then: https://www.ozbargain.com.au/search/node/lii
You can also buy any of these chargers from AliExpress, from the Liitokala official store.
Note that the Lii-500, Lii-500S and Lii-600 are not available with Australian mains plugs AFAIK, you'll need a mains plug adaptor to use these, or you can use an Australian figure-8 power cord with the Lii-600.
