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

The media could not be loaded. omg i’m so glad i thought to look for rechargeable c batteries — and even more glad they actually exist!my daughter has a sea soother in her crib that takes 4 c batteries, and when we used regular ones, they were dead within a week. i was honestly shocked and super disappointed — no way was i going to keep buying c batteries every week.i found these, and at the time they were the cheapest rechargeable c batteries on amazon — figured it was worth a shot. and safe to say: they’re amazing. they claim to last through 1,000+ charges, which is a huge money-saver over time. they feel solid and well-made (same weight and size as regular c batteries), and they fit perfectly in the soother, which reassured me that they’re true to size.we use the soother for every nap, bedtime, and night waking, and we’ve only had to recharge these every 4–5 days. yes, they do take a bit to fully charge — about 1.5 to 2 hours — but that’s not a big deal, especially since they come with one single charging cable that charges all four at once. (lifesaver. i’d go nuts with four separate chargers!)we’ve had zero issues: no overheating, no charging errors, no breakage. just reliable, reusable power. if you’re using anything that eats through c batteries, get these. highly recommend!

Brilliant product. Wish this setup was available years ago. Great value. Recharge time is reasonable also.

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.

These Messule rechargeable lithium D batteries are a good fit for regular D cell battery replacements. Plus they are rechargeable which means you shouldn't need to buy these over and over again. They provide the same energy level as regular batteries, and while they cost a bit more initially, they are a better value over time. They are a bit lighter than a regular battery which is a bit odd feeling, but they work very well regardless. They come with a four cord charger, so this six pack can charge four batteries at a time. I am using them as battery backup and only need three, so I'll have one set in and one set ready. There is a built in light to see when the battery is charging versus charged. Overall I would say this is a good set of batteries.

These rechargeable batteries have been a total game-changer. They charge up quickly and hold their power for a surprisingly long time, my kids use them in things every day and I haven’t had to recharge nearly as often as I expected. It’s such a relief not having to constantly buy new batteries, which was getting expensive fast. These have already saved me a ton of money, and they’re super easy to use. If you’re tired of throwing away batteries and wasting cash, this is definitely the way to go.

Got 4 of these for 2 of our decorative battery powered flickering candles. Two Alkaline C cell batteries last about 2 months (operate 5 hrs per day) in the candleand are not cheap. Got these rechargeables in hopes of reducing cost.However, a pair of rechargables only last about 3 weeks on a charge -- that's about 38% the life of alkaline batteries.I am 3 months into this experiment and convenience wise this is not good, but financially the jury is out.The "4 at once" charging octopus charging cable works fine and easy to use.UPDATE AT 8 MONTHS: One of the Li batteries has failed (will not charge, shows green "I am charged" light but voltage very low). Other 3 batteries show good voltage and charge normally.
