## Description

New Upgraded Battery for Galaxy S21 Plus, EB-BG996ABY Replacement Battery Compatible with Samsung Galaxy S21 Plus, with Repair Tools & Instruction

Review: Defective Battery - Received defective battery. Old battery was charging phone but charge was not lasting. So I purchased this replacement battery for my Xiaomi 9T Pro. Item received with packaging in tact and installation attempted as per instructions. However new battery would not charge. On examination of old and new batteries, new battery is missing a metal part on the end. I am not in US. Return will be costly and is not an option. Now I'm stuck with a defective battery I cannot use 😩
