About this replacement
Coolpad Torino S / E561 — 3.85V Li-Polymer Replacement Battery (CPLD-396)
This is a 3.85V, 1600mAh Li-Polymer cell that replaces the original CPLD-396 battery in the Coolpad Torino S and E561 smartphones. It restores power to a phone that no longer holds a charge or shuts down unexpectedly. Dimensions are 73.00 × 50.46 × 3.05mm — verify clearance before installing.
- Torino S and E561 compatibility: Both models run the same 3.85V power rail, share the CPLD-396 connector pinout, and use the same BMS handshake protocol — one cell covers both devices without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the E561 platform. The BMS accepted the charge IC handshake on the first cycle and held voltage through screen-on and modem-active load conditions without dropping into protection cutoff.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.
Sudden shutdown at 20–30% on the Coolpad Torino S after a cell swap
The Torino S fuel gauge IC retains the discharge curve of the old cell after replacement. When the new cell's actual voltage drops below the old curve's reference point — typically around 3.6V under modem or display load — the system sees a cliff and triggers an emergency shutdown even though percentage still reads 20–30%. This is not a fault with the replacement cell. One full discharge-to-zero followed by an uninterrupted charge to 100% gives the coulomb counter enough data to remap the curve. After that cycle, percentage readings track actual cell state accurately.
Phone will not power on after the replacement battery sat in storage
Li-Polymer cells self-discharge in storage. If this battery shipped at low state-of-charge and sat unused for weeks, cell voltage may have dropped below 2.5V — the threshold at which the BMS latches into lockout to prevent damage. Plugging in and seeing no response, no charging LED, and no boot screen is the classic sign. Connect the phone to a wall adapter — not a PC USB port — and leave it for 20–30 minutes without attempting to power it on. The charge IC needs time to trickle current into the cell until voltage climbs above the BMS unlock threshold of approximately 2.8V, at which point normal charging resumes.
