EBL Rechargeable C Batteries (4 Pack) and LCD Smart Battery Charger for Ni-MH AA AAA C D Rechargeable Batteries

These batteries hold their charge for 7-10 days and work great. We hated throwing away batteries weekly using them in our daughter’s toys, so this was such a good alternative. The base can accommodate size D all the way down to AAA and takes roughly 4 hours to charge C batteries to full capacity

The charger works well, and EBL's customer support is excellent. I love the display and how easy it is to know if your battery is charged. I charge C size batteries but plan to add other battery sizes since this charger can handle many different sizes. I did have an issue with the first charger that was sent, and I contacted EBL to troubleshoot. They responded quickly and ended up sending me another unit. They were very easy to work with!

The batteries are kind of tough to get to charge. They have to sit in the charger just right.

I ordered this to charge C-cell batteries. It charges (almost) all my rechargeable batteries without issue, but with a few AA's I have, it simply says "error" when I insert them; these same batteries charge perfectly well on my wall-plug chargers. My real problem: I had to buy another cord in order to use it properly. The cord it came with only powers it if I use only the left or right half of the charger and not the other half. As soon as I have at least one battery on the left half and one on the right, the whole screen starts flashing and refuses to charge anything. This was the case with both the included micro-USB cable, and my own USB-C cables. I did eventually find that a micro-USB intended for data transfer (not just device charging) makes it work like a charm. I still mostly stick to my smaller wall-plug chargers for my AA and AAA batteries, but when I have a lot to charge at once, or when the Cs need charging, this is a good item. The batteries that came with this set seem to be of very good quality - they charged quickly, and lasted longer in my household devices than other rechargeable C batteries I've bought.

So far so good! I really the like the fact that the charger will charge all battery sizes (BONUS) and the charge time was super quick (I talking within hours they were all four fully charged and ready to go). I purchased to use for a path light which isn’t solar (long story but not what I wanted at all) and our big flashlights. I have been using the batteries for a week now, and they are still charged, so I am hopeful they will continue to be a good purchase!

I purchased these for my fish tank filter. When I first got them, 4 weeks ago they would last 2 days. But after just 4 weeks, they only last 24 hours. I charge one set while using the other. Once they are fully charged, I unplug them and put them in the supplied storage. However when I go to use them, just 24 hours later, they only showing one bar and I have to charge them again before using them! So my filter cannot run until they fully charge for a second time. They are horrible and I would recommend you NOT buy them. They're a waste of money.

So far so good, charging doing its job waiting to see down the line how long the charger holds up but so far very pleased with this item

The charger works, but that's a conclusion I came to only after switching to a high power USB source. When plugged into a cheapo phone charger, the unit freaked out if I had batteries on the left and right halves of the charger. If you put 2 batteries in the left it worked. Add 1 to the right and it started flashing and looked like it was stuck in a boot loop. Even if you put just one battery in a left slot and one in a right slot, it would freak out, but on a high output USB feed, it works normally, so it has minimum USB power requirements that are higher than what some chargers can put out, which seems to me like poor circuit designAlso, the charger design is just weird. C-cell batteries use 2 neg terminals and 1 pos, so you're fighting 2 spring loaded forces which just feels like you're doing it wrong even though you're not. Poor ergodynamics. Adding a trough in the plastic for the larger batteries to catch into might make it feel like less of a balancing act to get the cells into the right position and it wouldn't cost any more to make. Just need to modify the injection mold to add ridges to the top to help guide the batteries into place. OK. Maybe it costs an extra fraction of a cent in additional plastic. It's just too easy for batteries to slip out of alignment and I feel like I'm fighting with it instead of it accepting the batteries.In case you're wondering, it only does 5v USB. It doesn't understand the higher voltage protocols for like 9v, 12v, or 20v. Just the basic 5v. It does accept AA and AAA rechargeables, but because of the bad design, I doubt I'll ever use it for them. My other chargers are just easier to load up.
