    Battery advancements thread

    It depends. If you pay a cycle life penalty equal (or less) than a gain in capacity, it's all OK. However, usually it is more.

    These look interesting, but I wonder what would the cycle life be.

    Any new "high end" chargers in the near future?

    Yes, it's expensive. It's fiddly only as far as you can change and control any charging parameter on any chemistry. No other charger gives nearly the same amount of flexibility and control, not even close. If you don't want to fiddle with it (which is done once), you can use it in some of the...

    21700 Charger Recommendation?

    IMO, the SkyRC MC3000 is the best consumer charger for cylindrical cells with two drawbacks: price, and not fitting protected 21700 cells. The new Xtar VP4L (new version of the VP4 Dragon with longer slots) can handle protected 21700, and should be cheaper than SkyRC MC3000.

    What Brands For 14500 & 18650?

    For unprotected 18650, look for Murata/Sony, Samsung, Panasonic, LG and Milicell. For protected ones, look at manufacturers that use the above mentioned cells. The best home charger for unprotected cylindrical cells is SkyRC MC3000

    Nitecore F1 vs F2

    Yes, try with another cable first. Even the problem is stil in the PB, I don't see many other alternatives. After all, in this age of cheap Chinese goods, 3 years of service is about what you can expect from such a product, so consider buying a new one.

    Nitecore F1 vs F2

    What's wrong with the PB2S? I've had one for about 8 months and use it almost daily (with a pair of E50 21700 cells) with 0 problems. Check the cables you are using, it is not unusual that the USB-C cables cause a problem with fast charging devices. AFAIK Nitecore F1 and F2 PB/chargers are...

    Acebeam E70 Review

    When I first read your (excellent BTW) review, I was puzzled by the high standby drain, since I haven't noticed any of this during my 6 months use of this light. Glad to see that it has been corrected now.

    BATTERY QUESTION

    The batteries should be kept in a dry cool place. Packaging doesn't matter much, unless you keep them refrigerated and want to avoid condensation when taken out of the fridge. I keep my AA/AAA NiMH at room temperature in plastic storage containers.

    LION empty for 24 months

    It's not unusual to get batteries that are about two years old. It's not the best situation, but I have several cells manufactured in 2020 and 2021 that still measure and work well. So, i'd say that modern Li cells can be stored for 2-3 years without adverse effect. If the phone was kept in a...

    Convoy S2+ punching in the positive terminals of battery - should I worry?

    This happens when the positive terminal has a hard-mounted pin instead of a spring, and the light has been subjected to some shock. However, my S2+ has springs on both terminals. I've been using it for couple of years with no issue. Can you post pictures on yours? About the cell, it is best to...

    Store brand batteries or Energizers? - LED Flashlight

    As others have said, you can't get much output and runtime on 3xAAA cells, 1200 lm is a no-no. The best is to get a light that uses Li-based cells, either 18650 or 21700. There are budget-friendly options from the like of Convoy and Sofirn.

    Panasonic NCR21700T

    And yet another thing. Panasonic 21700 (being made exclusively for Tesla) are very difficult to obtain, unlike Samsung, LG, Molicell and Murata/Sony.

    Panasonic NCR21700T

    I'm sure it is not a bad cell, being made by Panasonic, but what's the advantage over, say Samsung 50E?

    True 1.5v AA and AAA batteries

    The only brand I've used was XTAR. Used them for several cycles before giving them to a family member that uses them now (approx 1 year later). No complains about high self discharge or anything else. I guess different brands use different quality cells and electronics. XTAR are known to make...
