Motorola BK10 V950 Renegade Replacement Battery 3.7V 1600mAh

Motorola V950 Renegade / i465 Clutch — 3.7V Li-ion Replacement Battery (BK10 / SNN5793A)

This is a 3.7V, 1600mAh Li-ion replacement cell for the Motorola BK10 battery. It fits the V950 Renegade, i296, i465 Clutch, i335, and seven additional iDEN and CDMA handsets that share the same BK10 form factor. Voltage and dimensions match the OEM spec exactly: 44.80 × 37.30 × 10.50mm.

• V950 and iDEN i-series platform fit: These models share the BK10 footprint, connector pin-out, and 3.7V nominal rail. The BMS handshake is consistent across the group — the phone's charge IC does not distinguish between iDEN and CDMA variants at the cell level, so one replacement SKU covers all listed models without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a V950 unit. The BMS accepted charge without fault codes, held voltage above 3.5V through mid-discharge, and triggered cutoff cleanly at the low-voltage threshold — no premature trip on screen or radio load.
• Fuel gauge recalibration on first cycle: After installing this cell, disable any fast-charge accessory and run one full discharge-to-charge cycle at standard current. The V950's fuel gauge IC was calibrated to the original cell's discharge curve — one full cycle lets it map the new cell before high-current charging pushes current into an uncalibrated coulomb counter.

Why the V950 Renegade shuts down suddenly at 20–30% after a cell swap

This happens because the fuel gauge IC still holds the discharge curve of the old, degraded cell. When voltage drops under combined modem and screen load, the phone hits its hardware cutoff threshold while the gauge still reads 25%. The BMS cannot sustain voltage above the cutoff floor during a radio transmission burst, and the phone drops out before the gauge catches up. One full discharge-charge cycle forces the coulomb counter to remap against the new cell, and the shutdowns typically stop.

Phone not powering on after the replacement cell sat in storage

Li-ion cells self-discharge during storage. If this cell dropped below approximately 2.5V, the BMS entered lockout to prevent damage — and the phone will show nothing when you press the power button. Connect the phone to a wall charger, not a PC USB port, and leave it for 15–20 minutes without pressing any buttons. Most BMS circuits will begin a trickle pre-charge at low voltage and release the lockout once the cell climbs back above 2.9V. If the charging LED does not appear within 30 minutes, try a different cable before drawing any other conclusion.
