ZTE Grand X View 2 Replacement Battery LI3945T44P8HA69203 4400mAh

ZTE Grand X View 2 / Zpad 8 — 3.85V Li-Polymer Replacement Battery (LI3945T44P8HA69203)

This 3.85V, 4400mAh lithium-polymer battery replaces part number LI3945T44P8HA69203 in the ZTE Grand X View 2, Zpad 8, K83, and K83V tablets. It matches the original cell's voltage, capacity, and connector configuration. Dimensions are 104.75 × 95.50 × 2.60mm — confirm clearance inside your tablet before ordering.

• K83 and K83V platform fit: The Grand X View 2 and Zpad 8 both run on ZTE's K83 hardware platform, sharing the same battery bay dimensions, connector pinout, and BMS communication protocol — which is why a single part number covers all four listed models.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on K83-platform hardware. The BMS accepted the cell without fault codes, voltage held steady under combined display and Wi-Fi load, and the protection circuit triggered correctly at low-voltage cutoff.
• Fuel gauge recalibration after swap: After fitting this battery, run the tablet down to automatic shutoff — do not force-power-off — then charge uninterrupted to 100%. The K83's fuel gauge IC calibrates against the new cell during this cycle and eliminates the incorrect percentage readings that appear immediately after a swap.

ZTE Grand X View 2 shutting down at 15–25% remaining

This happens because the fuel gauge IC is still calibrated to the discharge curve of the old, degraded cell. When a new cell is installed, the IC's stored curve no longer matches actual cell voltage under load. The combined draw from the display backlight and active Wi-Fi creates a brief voltage dip the IC misreads as a low-battery cutoff. Run one full discharge-to-shutoff cycle followed by an uninterrupted charge to 100% — after that single cycle, the IC recalibrates and the early shutdowns stop.

Fast charging not available after battery replacement on the Zpad 8

The K83 platform uses a handshake between the charge IC and the battery's BMS before enabling fast-charge current. On a freshly installed cell, that handshake hasn't completed yet and the device defaults to standard 5V charging. This is not a fault — it resolves after the first full accepted charge cycle. Connect to your original ZTE charger, let it complete a full charge to 100% without interruption, and fast charging will be available from the next session onward.
