An absolutely nerdy show 'n' tell of my new 4th generation Panasonic eneloop Nickel Metal Hydride AA cells. Let's now check the cell capacities out of the packet and then give them a full charge and discharge.
Overview: All Eneloop batteries 2005-2014 - http://budgetlightforum.com/node/7336
Initial discharge results:
All 4 cells very similar: 1380mAh +/- 6mAh (approx 69% capacity)
Pack date code: December 2013
After a Refresh/Analyse (full charge, discharge to 0.9V and measure, full charge):
1907mAh, 1891mAh, 1894mAh, 1895mAh.
Presumably this will improve after a few charge/discharge cycles.

    Maha Powerex is the worse charger as a few of us bought them and gave up after a year or so usages.

    Hi Jullian. Have you already tested the Ikea Ladda 2450mAh? By looking at the reviews all over youtube they seem to be Eneloop Pros. Gongrats by the channel by the way!

    They all want our money.
    Make sure they deserve it.

    I tested each 3 tines.
    Elb's ruled every single time.

    Do you know what?
    It's a mistake to blindly follow.
    Chev Ford – whatever.
    They both get you home.
    Things change.

    Policy changes usually built on cheaper to boost profits and screw the customer.
    I know this – I bought 8 eneloop pro's, 8 eneloops and 4 ELB's

    As far as self discharge goes – if I haven't used a battery for a month I'm giving it a quick topup anyways.
    All only take a couple of minutes.
    If I haven't used it in a year then I don't really use batteries right?
    I may as well just buy dollar store junk.

    I tried to be an eneloop nerd.
    I ordered 4 eneloops, 4 eneloop pros and 4 ebl's.
    After 2 weeks of real world testing the eneloop pro's are the worst.
    Eneloops second.
    Ebl's first.
    Every time.
    .
    I tested several times using exactly the same equipment.
    AA running a fan.
    7 hours – Eneloop pro
    10 hours – Eneloop
    13.5 hours – Ebl
    .
    Similar results with aaa running a ust splashflash.
    .
    I know what I'll be buying now.

    What is the best place to buy Eneloop batteries and chargers?

    This video changed my attitude about rechargeable cells. My wife used to buy me a set or two for our cameras, but now days we simply buy huge bundles of Duracell's and toss the old ones when they die, however I wanted something better for my Nikon 14MPXL 21 Power Zoom camera, so I purchased a set of Enelope, well two sets so I could always have a set on hand that was ready in case of a needed recharge on the main set. Not long after I found an old GPS unit on Ebay, like the Nikon it had suffered a battery leak, and like the Nikon, nobody else would bid on them so I got both for opening bids, and both were (thankfully) an easy clean up since the leaks only effected the door end of the battery holders. So now both sets are happily powering their units, the GPS is a hand held unit with tons of functions that will assist me with contests using my Ham set where exact coordinates are necessary and the little hand held GPS unit gives all sorts of data on location, elevation, lat and lon, and of course a monochrome map display since it is a small hand held unit of exceptional age.

    You need to get out more often.

    What is going on with Youtube?

    The last few weeks all I am getting served up as suggestions are really old videos from all those I have subscribed to… Case in point… This video from 2014.

    It appears that Youtube is slowly not showing me videos I have seen several times and now decided I should time travel.

    Eneloop has horrible customer service here in Canada. I think they had a bad batch a couple of years ago. I bought 8 4pc AA 2000ma packs and 3 packs so far have defective cells. The more research I do the more I'm finding people having the same problem with this exact battery. There is no warranty on these batteries so be warned.
    The only eneloops that I'm having issues with is BK-3MCCA 1.2V min 1900mAh

    Can an eneloop nerd like you answer this question?

    Just bought some eneloops to use in a trail camera. After getting home, noticed the small print includes this: "Do not use in water proof flashlight or any device with an air tight battery compartment." Since trail camera is obviously used outdoors in all weather, it has a well-sealed battery compartment. Whether it qualifies as "air tight," I do not know.

    Also, I should say that I previously used Energizer rechargeables thousands of times in the trail cameras in all weather with no problem (except for predictable loss of effectiveness).

    So, what are the chances the eneloops will damage my trail cameras? Are they likely being overly cautious with their warnings?

    Any input appreciated!
