Released in August 2023, the Galaxy Z Fold 5 is Samsung’s premium foldable smartphone featuring a 7.6-inch Dynamic AMOLED 2X inner display, a 6.2-inch cover screen, and the powerful Snapdragon 8 Gen 2 for Galaxy processor. After 2-3 years of daily charging cycles, the original dual-battery system degrades significantly. This Li-ion Polymer battery set restores the full 4400mAh capacity, bringing back the all-day performance this flagship device was designed for. Both batteries are built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified. Designed for Foldable Innovation — Dual-Cell Architecture: The Galaxy Z Fold 5 uses a dual-cell series battery design — a requirement for foldable phones. The main battery EB-BF946ABY provides 2020mAh capacity and the secondary battery EB-BF947ABY provides 2380mAh capacity, combining for a total of 4400mAh (3.88V × 2 cells in series). This dual-cell configuration enables 45W wired fast charging and 15W wireless charging while distributing the battery across the two halves of the folding mechanism — one cell in the left half, the other in the right half. This clever design maximizes battery capacity without increasing device thickness when folded. However, both batteries must be replaced as a matched set. Using one old and one new battery causes unbalanced charging, reduced total capacity, and potential safety issues. This complete set ensures both cells have matching capacity, internal resistance, and charge cycles — critical for the dual-cell series configuration. Common symptoms of battery degradation in the Z Fold 5 include: the device requiring multiple charges per day, unexpected shutdowns at 15-25% battery remaining, slower charging than when new, or visible battery swelling. This replacement restores the original battery life and charging capability, extending the life of your foldable device without the cost of a new phone. Compatibility Note: Fits Samsung Galaxy Z Fold 5 (SM-F946B, SM-F946U) only. Please confirm your battery models before ordering — EB-BF946ABY and EB-BF947ABY are printed on your original batteries. This battery set is NOT compatible with Samsung Galaxy Z Fold 3, Z Fold 4, Z Fold 6, Galaxy S25 series, or other Samsung models. The Z Fold 5 uses a specific dual-battery configuration with distinct dimensions and connectors. Discover more from Battery.qingsm.tech Subscribe to get the latest posts sent to your email.
