I am satisfied with the product, the quality is excellent. I recommend this seller and store.

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!
