Replacing the Dell Latitude 7400 2-in-1 battery

powercfg /batteryreportand compare full-charge capacity with design capacity, or use our battery health analyzer. - • Replace when full-charge capacity is near 60-70% of design (about 51 Wh on a 78 Wh pack) or the laptop shuts down early.
- • A swollen battery is a fire risk: stop charging it and bring it in. Do not press the case back down.
- • Buy the same capacity and part number as the old pack. A bigger factory option (78 Wh) only fits if the model was sold with it and the bay has room.
