USB Rechargeable Lithium D Cell Batteries - 4 Pack D Li-ion Battery with 2 USB-C 2-in-1 Charging Cable, 1.5V 10000mWh, Quick Charges 2 Hours, Over 1000+ Cycles

So, so good. These rechargable D' cell batteries are already saving me money. I use a couple of Mag Light flashlights that use D' cell batteries, and these rechargable are perfect for them. Not the first of these rechargable that I've used, and they seem to last forever charge after charge....

Purchased these to run some light fans in our camper. We were going through 2 every three nights. Thought these would be a good option. Starting the fans on low about 10pm sees them run until about 4am. Standard batteries on low during the same would result in 3-4 full nights of use. Batteries seem fair enough quality, and if you weren't running them to depletion would be a fair value. For our application, they're not perfect, but fair enough to recommend.

Tired of replacing batteries? Purchased these. They work great and recharging is so easy!,

Waste of money. They charged one time and that’s it only worked for 48hrs tried to charge them for a catching time the light started solid green but the batteries didn’t work

Real Capacity is 3Ah.(1Amp for 3 hours ) The voltage is at all times (under 1A load just 1v instead of 1.5 v) So the real capacity is 1v × 1A × 3hr=3Ah or 3000mAh.
