4 Packs Rechargeable Battery 3.7V 3500mAh Flat Top Battery for Headlights etc

The batteries work great, fit my flashlight nicely and so far the one I've used has lasted way longer than the original battery

This is my 2nd order for these rechargeable batteries. At this time I have not used them, however I am currently using the second battery from my original purchase. The batteries work well and last along time between charging.

Works Great , Low Price , Fast Shipping

Works great but a full charge does not charge my iPhone completely. I was able to get about 40% charge

Great batteries.The original in hair clippers for my dog would die too quickly.Each one of these lasts 3 times as long.

Arrived on Friday, they are 2mm shorter than the OEM Ring battery that you cannot buy so I had to stretch the negative contact spring to make sufficient contact in the pathlight.Charged it fully overnight then put outside on Saturday in a sunny location and it worked as expected that night.Sunday came and I got the notice on my Ring app that it is offline due to low battery, but it was going to sit out in the light all day so I left it sit outside for the solar panel to charge it.However it did not charge at all.Then hooked it back up to the manual charger in the evening and it still would not charge.Junk.

My batteries came on time and I soldered them into my bluetooth speaker.Took a few hours for a full charge. Now the capacity is almost 24 hours at 1/3 volume . Up from 8-10 with original batteries.The original batteries were generic with the blue wrap just like these and they lasted 5 years.I had bought these other ones with the green label claiming really high amp hours, and they petered out after a few months , and had actually less capacity than the original batteries.Don't buy those , green label called SKY something or other, total crap .So far so good , and I would definitely go with any of the generic batteries with the blue wrap over most of the others with flashy names and unrealistic claims .

Fitted perfect in the radiomaster pocket
