## Description

MAXSHARKS Replacement Battery for Galaxy Watch Active 2 (40mm) , EB-BR830ABY Battery Compatible with Samsung Galaxy Watch Active 2 40mm SM-R830 SM-R835, with Repair Tools & Instruction

Review: Wrong tool sent - To do this battery replacement you need a y00 3 blade screwdriver they sent a .06 which is too big I had to order a Y00 screwdriver to remove and reinstall the screws. The instructions were good except for either the second page was missing or they were incomplete. The watch did work when done I would advise a magnifying device and a bright work area.
Review: Worthless - The tri-point screwdriver would not remove the screws on the back of the watch.
