About this replacement
Motorola A6088 / A6288 / Accompli A008 Series — 3.7V Li-ion Replacement Battery
This 3.7V, 1050mAh Li-ion cell replaces the original battery in the Motorola A6088, A6188, A6288, and Accompli A008 series smartphones. It fits the same form factor and connects to the same charging circuit as the factory cell. Use the capacity figure from the product listing — 1050mAh — not inflated third-party claims.
- A6088 / A6188 / A6288 / Accompli A008 compatibility: These models share the same battery bay dimensions, connector pinout, and charge management IC voltage rails, which is why one cell covers all variants on this list.
- Bench tested on actual hardware: We cycled this cell through the A6288 charge IC and confirmed the BMS accepted the full charge sequence without tripping into protection mode or reporting a fault state.
- Fuel gauge recalibration tip: On first use after installation, disable fast charging if your carrier firmware supports it, then run one complete discharge-to-charge cycle — this lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging begins.
Sudden shutdown at 20–30% on a freshly installed cell
This happens because the fuel gauge IC is still using the discharge curve it learned from the old, degraded cell. When the new cell hits a voltage region the IC doesn't recognise, it triggers a premature shutdown rather than risk a brownout. The fix is to run two or three full discharge-charge cycles without interruption. After those cycles, the coulomb counter resets its endpoint estimates to match the new cell, and shutdowns at false-low percentages stop.
Phone not powering on after the replacement cell sat in storage
Li-ion cells self-discharge in storage. If the cell voltage dropped below approximately 2.5V per cell before installation, the BMS will lock out charging as a safety measure and the phone will show nothing on screen. Connect the phone to a wall charger — not a USB port — and leave it for 20–30 minutes without pressing any buttons. Most Motorola charge ICs include a trickle-charge recovery mode that slowly raises the cell to around 3.0V before the BMS unlocks and normal charging resumes.
