Gigaset GS180 Replacement Battery 3.85V 2850mAh

Gigaset GS180 — 3.85V Li-Polymer Replacement Battery (V30145-K1310-X467)

This is a 3.85V, 2850mAh (10.97Wh) lithium-polymer cell for the Gigaset GS180 smartphone. It replaces the original battery when capacity has faded and the phone can no longer hold charge through a normal day of calls, messaging, and mobile data. OEM part number V30145-K1310-X467 confirms the correct fit for this model.

• GS180 cell specification: The GS180 uses a 3.85V nominal Li-Polymer cell with a specific connector orientation and BMS handshake tied to the charge IC on the motherboard. Swapping to a cell that matches the original voltage rail and connector pinout keeps the charge circuit operating within its programmed parameters.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on GS180 hardware, confirmed BMS communication was accepted by the charge IC, and verified the protection circuit trips correctly at the low-voltage cutoff threshold.
• First-cycle fuel gauge calibration: On first use after installation, disable fast charging and run one full discharge-to-charge cycle. The fuel gauge IC on the GS180 carries calibration data from the old cell's discharge curve — one complete cycle lets it recalibrate against the new cell before high-current charging begins.

Sudden shutdown at 20–30% on the GS180 after a cell swap

The GS180's fuel gauge IC was calibrated to the discharge curve of the original, often degraded cell. A new cell has a steeper voltage cliff under modem and screen load, so the reported percentage and the actual usable voltage diverge. When the phone pulls current for LTE transmission or screen wake, the cell voltage drops sharply and the protection circuit cuts power before the gauge reaches zero. One full discharge-charge cycle — draining to automatic shutdown, then charging uninterrupted to 100% — resets the coulomb counter against the new cell's actual curve.

GS180 not powering on after the replacement battery sat in storage

Li-Polymer cells ship in a partial charge state. If the cell sat in a warehouse or in transit for several months, self-discharge can push voltage below the BMS lockout threshold — typically 2.5V per cell. At that point, the BMS opens the discharge circuit and the phone will not respond to the power button or a standard charger. Connect the phone to a 5V USB charger and leave it undisturbed for 20–30 minutes — the charge IC will attempt a trickle pre-charge recovery cycle. If the cell voltage recovers above 3.0V, the BMS re-closes and normal charging resumes.
