    Overview: All eneloop batteries; 2005-2021

    Sharing my Eneloop collection. I tried to pull back 2-4 of each type to take this picture. You see 26, but I have another ~50 or so currently in devices. All of these get used. I'm not really a collector, but I have made an effort to find different colors when I have needed to order. I've also...

    When do you retire old AA/AAA batteries?

    I’ve still got 10 of 12 of my original 2006 manufactured Eneloop AA, and 4 out of of 8 AAA. 2 of the AA failed, one had physical damage, the other developed rapid discharge. I killed 4 of the AAA in a 4 cell radio with parasitic drain that kept discharging them to zero for long periods of...

    The Official Zebralight Thread .

    Per Zebralight, the H52 is 500 lumens for the warm white, and 535 for the regular tint on 14500. For AA, they show 280 and 300 lumens respectively. They don’t list any figures for the H53 on 14500, which as others have noted, was not listed by ZL as supporting the higher voltages.

    Small Portable Radio's?

    Update on my post about the cheapie antenna that plugs into the earphone jack / miniature plug. In short, it works great. I still expect there are times when the fully extended earphone wire can do a better job, but I couldn’t produce that result with the signal I experimented with. Instead, I...

    Small Portable Radio's?

    Inspired by ezarc, I have ordered one of these for my CC Pocket Radio. Expectation: at 7” / 17cm long, it won’t match the fully extended earbuds or wire antenna included with the pocket radio for FM / Weather bands. But those “wire” antennas are often in less than optimal orientations when in...

    NiMH D cells?

    I’ve had pretty good luck with the Tenergy Centura D cell LSD’s that I purchased in 2017 and 2019. Usage is in radios, I have 14 of these pricey wonder batteries. They certainly are living up tp the LSD requirement, as a couple of these radios sit on the shelf and rarely get used. Another gets...

    black enelope 2450 mah vs 21700 4400 mah?

    I have Original Eneloops from 2006 and 2007 still in service and going strong, as well as 4 Duraloops from that era. I think 3 out of 16 have failed, but 2 of those were crushed a little and had physical damage. 15 years of service, it’s just amazing. In the meantime I have tried Eneloop Pros...

    Energizer AA Lithium

    Recently I came across an old battery powered travel razor that I had misplaced. To my delight, and simultaneous horror, I found a pair of the old style L91’s inside, expiration 2009. The razor ran strongly when I turned it on, and I measured a voltage of 1.62 I was tempted to run a discharge...

    darkest place you have ever been?

    What fascinates me more than caves or other structures, which of course can block all of the light, are places with dark skies where you can easily see the Milky Way. The best dark sky places that I have experienced: Nepal, a small village at ~14,000ft and no electric lights. Big Bend National...

    Beware Alkaline Cells

    There are some things that you can make a use case for alkalines in if it wasn’t for the leak factor. Remote controls, clocks, cordless mice, etc.

    Beware Alkaline Cells

    IMO, it isn’t so much that the always leak. But it’s like playing Russian roulette, eventually the odds catch up to you.

    is zebralight sc5w ii the best aa light?

    Since you edited / added the spec for the Quark AA, I think you answered your own question. Here is a photo comparison to give an idea of the relative form factors. Note that the Quark AA also has a moonlight mode, if I remember correctly the projected runtime was in the 500 hour / 3 week...

    is zebralight sc5w ii the best aa light?

    I have an SC5, an SC5 MK II, and an SC53. The original SC5 was built like a tank, but seemed unnecessarily heavy, and the MK II did a nice job in trimming it down. The SC53 is a fine light, but never had the top end lumens of the SC5 models.
