Review on 🔋 Ruzixt 10.8V 2200mAh Battery: Compatible with Shark Freestyle Navigator XBT1106N & More Cordless Stick Vacuums by Barbara Lopes

My original battery lasted 2+ years with 15-20 minutes of use before needing a charge. I always used it until it was dead and then let it charge as suggested. This Ruzist replacement gave me 12-15 minutes of use the first few times which was hardly acceptable but the time quickly dropped to 6 minutes after a month and is now 4 minutes. I'm not sure if I should try a different brand of spare battery or throw the Shark away.
