  1. I use tons of AA, a handful of AAA, the odd N cell here n there, (all NiMH & NiCd) and li-ion 18650 & buttons. SO I had to get four chargers minimum. One just for buttons and one just for 18650 and then N cell is too short to fit in most “universal chargers”. If chargers recharge both Nimh & Nicd they tend to get the universal adjective, but not all of chargers have size adapter function. I will admit to being cheap on my chargers. and I have yet to purchase one for C’s and D’s but had an eye on the EBL /. The EBL is not on your good or bad brands so I’m guessing you not tested them yet =D

  2. What about EBL batteries? I heard their D and C cell are really solid. In fact the only knock I have heard is on their (EBL) 9V battery. EBL\s 9v is not really 9 volts lulz. I shrugged when I learned this, with all factors such as pricw considered, the SunLabz 9V looked better to me on paper. So it’s not like the Chinese crap with false and inflated stats. It’s more solid battery companies (Tenergy’s & EBL’s 9volt in this example) simply don’t make EVERY battery size in stellar quality. But I digress, what does EBL’s absence mean in your rechargeable D battery recommendation? No troll intended, just curious of your opinion. I heard good things about EBL’s D battery.

  3. Got a good charger. Unfortunately, I’m stuck putting the Eneloop Pro in the 30 minute charger because the good charger I have has trouble terminating correctly on AAAs. Others are having the same issue.

  4. Never mind on the lantern spacer pack for the D cells batteries. Found one sold by Canadian Tire by Dambi I think it was.

  5. Another super interesting article from Meta Efficient!! No other website I know covers this info!
    Does anyone know why Eneloop has D size batteries in Japan but not North America?
    Also can anyone recommend a lantern battery spacer pack that accommodates D size batteries?
