I'm a big fan of Eneloop batteries. The long shelf life doesn't just translate to usable batteries after a long time lying around, but also a longer battery life in general. I had several packs of Duracell which wouldn't hold a charge after 5 - 6 years of mixed storage and light use in remote controls; They saw maybe three to four dozen discharge cycles at most. Meanwhile some Eneloop AAs I bought back in College for my camera flash and mic are still going strong, and they are around twice that age.
This pack of AAAs was sold by 'MYBATTERYSUPPLIER', and you should always check who is selling them before you buy. In this case the listed quantity of batteries was correct, manufacturing date was reasonably recent (2 yrs ago on mine), and I used an online guide to verify the authenticity of the batteries. Most of the negative reviews you see on 鶹 are people saying they got fakes, so just make sure you check the seller's sign-up-date and ratings, and you should be fine.
One final word of wisdom, mAh is used as a marketing term. It's tempting to get the highest value you can find, but there can be a few flaws to that logic. Firstly, manufacturers may use different testing methods, as well as cell qualities. While I'd feel confident getting X mAh from a known brand like Duracell or Energizer, it's common for cheap batteries to list inflated values. The second thing to consider is self discharge rate. Not only are low self discharge batteries likely to 'live' longer, but a standard NiMH battery can lose up to around a quarter of it's maximum charge in the first 24h after charging, just sitting around. So unless you are charging that shiny 2500+ mAh battery and draining it immediately, you can actually be getting less capacity than a low-self-discharge cell. This is less of an issue with know brands, but unless you use the battery soon after charging, you will still get less capacity than you might expect.
