My new 2600mAh batteries are awesome! My fan ran from 9 AM to 5 PM straight, and there was still juice left—way better than my old ones that died after just 3 hours. My husband actually tests batteries for work, so he brought home professional gear to check these. They matched exactly what was advertised—no fake capacity here. The full-charge voltage was right on spec, and it stayed super steady the whole time they discharged. Total quality batteries!

Tried these batteries as soon as they arrived. I put them in my flashlight with a T6 bulb, and they easily lasted 4-5 hours—no issues at all, and the brightness never faded. I don’t think the capacity is false advertising; they’re totally safe to use right now. I’ll come back to share more feedback if I have additional thoughts later!
