Vodafone EB504465VU Compatible Battery 3.7V 1500mAh

Vodafone 360 Series — 3.7V Li-ion Replacement Battery (EB504465VU)

This is a 3.7V, 1500mAh Li-ion cell for the Vodafone 360, H1360, 360 H1, and 360 M1 smartphones. It replaces OEM part EB504465VU and SO1S416AS/5-B directly. The cell measures 64.60 × 43.90 × 5.20mm — confirm these dimensions against your existing battery before fitting.

• 360 and H1360 platform compatibility: The 360, H1360, 360 H1, and 360 M1 all share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers all four variants without adapter or modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on 360-series hardware. The BMS accepted charge current correctly, thermal cutoff triggered at spec, and the protection circuit held voltage above the 2.5V floor under load.
• Fuel gauge recalibration after install: On first use, disable fast charging and run one full discharge-to-charge cycle before enabling high-current charging. This lets the fuel gauge IC map the new cell's actual discharge curve before pushing elevated current into an uncalibrated cell.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff issue, not a capacity fault. When the modem radio or display draws a high current burst, the new cell's terminal voltage briefly drops below the BMS cutoff threshold — even though the fuel gauge still reports 20–30% remaining. The old fuel gauge calibration does not match the new cell's discharge curve, so the percentage reading is inaccurate. Run one full discharge cycle without fast charging to force recalibration, and the shutdowns typically stop.

Phone reports wrong battery percentage after cell swap

The fuel gauge IC stores a learned model of the previous cell's impedance and capacity fade. Swapping in a new cell does not automatically reset that model. The result is percentage readings that jump, stall, or read 100% after a short charge. A single full discharge — down to automatic shutdown — followed by a full uninterrupted charge resets the coulomb counter and brings reported percentage back in line with actual cell state.
