Energizer Ultimate Lithium AA - 4 pack, $17.89

I've kept any eye out for deals on these ever since that $14.99 deal at PaknSave Royal Oak a few months ago.

If you go to Mitre10 and price match these + the 15% discount, you should then be able to get them for $15.20

  • Similar to a pack of eneloop rechargeables? Could consider that instead?

      this is not rechargeable

        Yeah why not get some rechargeables instead

          Looking at the datasheet, they seem to have stable performance in discharge environments up to 1A, with a large overall capacity, but pretty much on par with cheap batteries at low discharge (for a significant price premium).

          Compared to NiMH, and Eneloop Pros specifically, they have a much larger capacity once, but Eneloops are also stable at 1A (datasheets below, these are only tested up to 1A, with a drop from 3.5Ah down to ~3.3Ah at 1A, whilst the latter start at 2.4Ah and drop to ~2.35Ah at 1A).

          So, if you have an environment that needs maximum capacity at 1A once in AA form factor, and price is the lesser consideration, then these are the best choice.

          I couldn't tell you what that environment is…running an old AA based camera on an amateur weather balloons?

          But yeah, in any other circumstance if you have low draw and need max capacity (say a GPS tracker welded into a trailer), buy cheap alkaline batteries, if you have high draw buy Eneloop Pros.

        • @danvelopment comment has excellent technical explanation. In practice, these batteries are very lightweight and pack a punch of energy. I use these when I'm tramping in a satellite messenger/tracker and nothing has beaten these batteries in terms of how long these last. Also, spares are light to carry. Another place I use them is in smoke and CO alarms that take AA or AAA batteries - they last 4x longer than standard alkaline or rechargeable batteries. Definitely don't use them in kids' toys unless you're growing money on trees ;-)

        • I use these in temperature sensors where normal alkalines bail out very quickly in the fridge and freezer. They also last a hell of a lot longer for the contact sensors that I have to put in a bag to waterproof them outside on gates and storage boxes etc. They end up costing more than costco alkalines for normal indoor things, so not worth it where its quick and easy to swap them over, but for anything that I have to get a ladder out for or similar, the lithiums are worth the extra spend.
