Rechargeable Lithium D Batteries with 4 in 1 USB-C Charge Cable,6 Pack D Cell Li-ion Battries,LR20 1.5V D Size Cell Battery Replacement 7500mWh for Floodlight Toys(6 Pcs)

Light weight alternative for D batteries. Very impressed with quick charging and battery longevity. I highly recommend these.

Hand it to the Chinese for always coming up with new and convenient ideas. I bought these for my D Maglite flashlights since I'm coming up on 10 years and D size Li-Ion batts weren't around 10 years ago. Definitely hate batteries leaking, which happens often for devices that don't get used much. These batteries are lightweight (as are any lithium battery you would buy) and hold the charge well. Icing on the cake that they are rechargeable. I like the octopus charging cable too so you don't have to charge one at a time. Really impressed with this idea! We'll see how they hold up over the years.

I bought these rechargeable D batteries for my daughter’s little swing because I was getting tired of constantly buying new batteries every couple of weeks. I’m so glad I made the switch — these have definitely saved me both time and money in the long run.One thing I love is how fast these batteries charge. I don’t have to wait forever to get them back in action. The 4-in-1 USB-C charge cable is super convenient for charging all of them at once, which makes life much easier.Now, the one downside — they don’t last as long as I hoped, especially with my daughter constantly using the swing every day. They usually die within a few days, which can be a bit annoying, but I guess it’s expected when you’re using them so frequently in a high-drain device.Still, I can always recharge them quickly, so it’s not a huge deal.Even though they don’t last as long as I’d like, I feel good about the savings and the fact that I’m not throwing away disposable batteries every few weeks. Plus, they do the job just fine for everything else, so they’ve still been a great investment.Overall, these rechargeable D batteries are a solid option if you're tired of constantly buying new disposable batteries. They charge fast, save you money, and are eco-friendly. Just be aware that if you're using them in high-demand devices like a swing that runs daily, you might need to recharge more often.

These work great. Comes with the charger. Thought we had to replace our motion sensing trash can when it didn't work when batteries were replaced with regular batteries. But these worked.

I have a wireless door camera that takes D batteries. I've had it for over a year and have found myself buying batteries a lot more often than before...and it's not cheap! I decided to give these rechargables a chance and I have some feedback (good and bad):The Good: It seems to last a good month between charges but that can change based on how often someone walks by my apartment since the camera is motion-activated.The Bad: Instead of a green light like the product info says on here, mine all have red lights and they never blink so it's hard to tell when they are fully charged. They stay solid red and get really hot as I charge them and I'm sure that's not normal.Another bad thing (not necessarily the battery's fault) is that my door camera app can't tell when the batteries are getting low for some reason. It can tell with traditional batteries but these rechargables don't seem to interact well with the app so it will say it's fully charged when in fact they are dead.Overall, I will continue to use them simply because it's much cheaper than buying new batteries every month but I wish I could tell when they are fully charged and I wish my door camera app could register the battery level, as that's very useful for me.

I absolutely love these! I bought these for some of my kiddos hot wheels pieces that needed larger batteries. As we all know, C and D batteries are especially expensive and these really solve a problem for us. They are so easy to recharge and work really really well. I cannot recommend them enough.

The batteries look good, and I like using usb c charge because I had the hardware to charge. They are lighter than NiMH.The bad and the reason they get 1 star is, they are absolute trash (junk). Do not buy these. The negative side of all 8 (2x 4 pack) that I bought was pushed (caves in). Very flimsy. They charged ok, but when input then I to a flashlight, they would not work. I could make them turn the light on by moving them around and not screwing the flashlight cover on.Maybe I got 2x bad batches but enough was enough. I changed to Amazon basic NiMH d cells and bought a charger for them. They will work just fine in my flash lights for years to come.I will not buy Li rechargeable batteries u til the quality is much much better.

I purchased a set of 8 batteries C-Cell Equivalent batteries from messcule. These charged quickly and were installed in two LED motion sensor lights near interior garage doors on Dec 17 2024. Lights were bright and worked well. As with many lithium batteries lights stopped working 4/13/2025. Pretty good charging life. However, two of the batteries will now not take a charge. I don't know if the vendor has any warranty for failures in less than 6 months.
