BLI-248 SVP Kyocera DV-8300 Replacement Battery 3.7V 1000mAh

SVP DV-8300 / US-P — 3.7V Li-ion Replacement Battery (BLI-248)

This is a 3.7V 1000mAh Li-ion cell replacing the original BLI-248 battery in the SVP DV-8300 and US-P candybar-style mobile phones. It slots into the same battery bay and connects via the original contacts. Voltage and capacity match the OEM spec exactly — 3.7V, 1000mAh, 3.7Wh.

• DV-8300 and US-P fit: Both models run the same 3.7V battery rail and share the BLI-248 footprint — same connector pitch, same contact placement, same BMS handshake logic. One cell covers both.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the DV-8300. The BMS accepted the charge profile without tripping, and voltage held steady across the discharge curve under typical phone load.
• Fuel gauge recalibration on first install: On first use, disable fast charging if your charger supports it and run one complete discharge-to-charge cycle. The fuel gauge IC in older candybar phones calibrates to the new cell's discharge curve on that first pass — skip it and the percentage readout drifts.

Sudden shutdown at 20–30% on the DV-8300 after a cell swap

The DV-8300's fuel gauge IC was calibrated to the original cell's discharge curve. A new cell has a slightly different curve, so the IC misreads remaining capacity. The phone thinks it has charge left, but the cell voltage drops below the processor's minimum under load — call audio and screen draw together can spike current enough to trigger an abrupt shutdown. One full discharge-to-charge cycle lets the IC recalibrate. After that cycle, the percentage readout tracks the actual cell state correctly.

Phone won't power on after the replacement battery sat in storage

Li-ion cells self-discharge during storage. If the cell dropped below approximately 2.5V per cell, the BMS trips into lockout mode to prevent damage — the phone will not respond to the power button. Connect the phone to a charger and leave it for 15–20 minutes without pressing anything. The charge IC delivers a low-current trickle to bring the cell voltage back above the BMS recovery threshold, at which point the phone will boot normally.
