USB Rechargeable Lithium C Batteries - 8 Pack C Cell Li-ion Battery, with 2 USB-C 2-in-1 Charging Cable, 1.5V 5000mwh, Quick Charges 2 Hours, Over 1000+ Cycles

Nice rechargeable C-cell lithium ion batteries. They charged quickly and last about as long as a regular lithium C-cell battery. Worth the money.

Early winter 2021, I purchased 60 rechargeable C cells to power my battery-powered window candles through the Christmas season. Most of the batteries I purchased were Ray-Hom, but I maxed out the quantity I could purchase from them, and I purchased Amazon batteries to complete the set.For the 3 months I kept the candles in my windows in 2021-22, I had no issues. I charged all the batteries once, and they all lasted all season, powering LED window candles that were on from dusk to dawn daily.When not in use, the batteries were stored in a cool, dry location.Fast forward to this year. Once again, I charged all 60 batteries and loaded up the window candles for the season. The Ray-Hom batteries are performing as expected. After two weeks, they are maintaining a strong, bright light, and none have required any further charging.In contrast, several of the Amazon batteries are not holding up. There are several candles that have gone dead multiple times, in just the past 2 weeks, and all the ones that are going dead have Amazon batteries in them. I have recharged these batteries multiple times, and they are dead within 3 days.Unfortunately the Ray-Hom batteries that I previously purchased are not available on Amazon at this time, so I am looking for an alternative to replace the Amazon batteries.I would purchase more Ray-Hom batteries if I could, but I do not recommend the Amazon batteries if you want them to last multiple seasons.

Great batteries. I've gone to all rechargeable batteries and these are the best. They are long lasting and quick to recharge. They say they are good for 1000 charges and based on that I'll never have to buy them again. They are real neat in that they have the USB.connector built in to the battery and provide a cable to charge them. The only thing that you need is a USB charger like what you charge your phone with.

Just had them for about three weeks and placed them into my cd player for usage. That was after I charged them completely. The first time, I forgot to power off the player because I left the house. So, the next time, within a few days, I tried listening to my music, the batteries were already dead.Then, after fully recharging, I listened to my music, for a couple of hours, turned the player off, like powered it down. Did that a couple of times. The fourth time, no more battery power!The cd player needs 8 batteries to play, so I purchased 16 batteries to always have a backup.I sure did not expect to use the backup that soon.Update:After charging a few more times, the holding capacity is better. I'm glad to have kept the batteries.

I got tired of constantly replacing batteries in my roomba gate/fence things, so I decided to give these a try. They come with a nice short split cable for charging. They take a charge well, and seem to last plenty long. I haven't run a capacity test on them, but so far I haven't needed to recharge them in over a month. I like that you can plug the usb-c charger directly into the battery, and it doesn't require a bulky charging station.

Good power, and charge quickly! Supplied harness works well!! Don't need a special adapter for charging either, just a USB plug...

For the price and quality, these were the best rechargeable C sized batteries I could find. Purchased the 8 pack for my Portable ac/dc emergency radio. Radio uses 4 batteries. have used several for weeks and still charged to peak 1.20V.Checked pricing at several battery suppliers and went with these found at Amazon, very happy with purchase. Will save Big $$ by not continuing to have to buy alkali batteries. These batteries will easily pay back cost of ownership quickly.

The C-cell rechargeable batteries arrived 8/2/19. Charged them fully on 8/13/19 (they arrived with about a 50% charge each, as vendor has noted elsewhere). Then placed the four newly arrived & charged batteries into a Duracell brand 4-C-cell flashlight I own (that retails for around $29.50).Then hit the “on” switch. There was a brief flash of light then….nothing. No light at all. After testing same flashlight again – this time with regular, non-rechargeable batteries that I knew had worked fine in this flashlight moments earlier - it became obvious (to me at any rate) the LED in the light and/or the entire LED circuit had been blown in some fashion by installation of the newly arrived rechargeable C batteries.I could find no other obvious cause. From that point forward flashlight was not usable. As in, dead. No work at all.Not to be deterred, I tried the same newly arrived rechargeable C-cell batteries in a 2nd Duracell, 4-cell C flashlight (different model than first one, but a great light nonetheless).Same thing happened. Second flashlight (after a brief flash of light) was rendered no longer useable (as in dead for good no matter what batteries we tried). Threw both of those flashlights away (combined they had cost me around $50.00 not including tax). Returned the newly arrived rechargeable C-cell batteries to Amazon for refund. Will not be purchasing those rechargeable batteries again.
