2. Swollen Cell Chemical Release
We apply non-conductive adhesive dissolver beneath the battery tray, lifting the cell safely without puncturing the pouch.
3. Fresh Thermal Tape & Battery Fitment
We install the new high-capacity battery using pre-cut stretch-release tabs and replace graphite thermal pads.
4. USB-PD Power Negotiation Benchmark
We verify rapid charging handshake, check battery cycle telemetry, and clamp the screen with waterproof perimeter gaskets.
