winbasic Rechargeable Lithium D Batteries with 4 in 1 USB-C Charging Cable,1.5V D Size Cell Battery 5600mWh for Flashlight (8 Pack)

These are my go-to. Excellent quality, battery length, and value.

These rechargeable batteries a good for the price, however, they don't last very long in my small m portable fan. I am glad that I bought the 8-pack so I will always have charged batteries when I need them. They only sent 1 of the 4-wire usb charging cables... so I cannot charge all 8 batteries at the same time. I suggest that they include 2 of the cables to help with customer satisfaction. In addition, these batteries are very light in weight, which usually would be very good for most uses.... but in my case, the batteries fit in a compartment on the bottom of my fan and the weight of the batteries is supposed to stabilize the fan so it will stay upright. Because of the light weight of these batteries... I have to add weight to the bottom of my fan to keep it from falling over... although since my fan has a clip on it as well, many applications using the clip to attach the fan to a shelf or somethingbelse, the light weight of these batteries help the fan from not falling off the wall. So the weight of the batteries can be either good or bad...Otherwise, the product is good.

They are what you'd expect they work for me so far but they do concern me alittle as the tops get...very very hot when on charge like enough to burn you alittle but they work good for alittle bit

Good

We bought these to go into a baby seat. I love that they recharge and the wires that came with it is super convenient because you can charge all of them at once!
