Review on 50AA2500 EBL Individual Battery Charging System - Rechargeable Batteries by Perryn Watwood

******ORIGINAL REVIEW***** Decided to buy a kit (charger and batteries) to have spare batteries. At first glance you can see that the end of the batteries is rusted, and the only new thing is the cover, which almost does not fall off. However, I decided to try them and they didn't even last a couple of hours. First charge and one of them already shows an error (red light flashing) The charger still works but I would definitely NOT recommend buying a kit. ***** 7/21/22 UPDATE******** I was contacted by customer service who dealt with the defective batteries. I updated my review because this company really stands behind their products and strives to make customers happy with them. I personally like the USB charger, it works very well with the rest of my batteries.
