Review on 8 Pack BONAI 600MAh High Capacity AAA Rechargeable Solar Batteries - Perfect For Solar Lights Replacement by Christina Kharel

On receipt of my package I tested all 20 cells using a La Crosse BC-900 battery charger and a MaximalPower FC1000 smart charger which both have a test mode that shows the total mAh available for each cell. The results indicate the that 1 cell is 605 mAh and 17 are between 520 mAh and 582 mAh. Unfortunately 2 cells indicate they are null and cannot be charged. I believe the 18 good cells are close enough to the advertised 600 mAh and the numbers may increase after they are charged a few more times. I do not want to return all 20 cells but I would like a replacement for the 2 defective cells. I contacted BONAI directly by email but so far no reply. If I get my extra 2 cells I will update my review.UpdateA week after I contacted BONAI I received replacement batteries. Changing my rating to 5 stars for excellent customer service.
