CareStream DRX-1 Replacement Battery 14.8V 2100mAh 441400052

CareStream DRX-1 Series — 14.8V Li-Polymer Replacement Battery (441400052)

This 14.8V, 2100mAh lithium-polymer battery replaces the original power cell in the CareStream DRX-1 handheld intraoral digital X-ray camera. It fits the DRX-1, DRX-1 System Flat Panel Digital Imager 450, and DRX-1 System Flat Panel Digital Imager 465. Cross-references OEM part numbers 441400052, 8G5132, 1001163, SPAC1432, and SPAA1531.

• DRX-1 platform fit: The 450 and 465 imager variants share the same 14.8V battery rail, connector pinout, and BMS handshake protocol as the base DRX-1. A single cell design covers all three, because the charge IC communicates over the same data line across the platform.
• Bench tested on actual hardware: We cycled this cell through the DRX-1 power-on self-test sequence and monitored BMS communication at each stage. The protection circuit held within spec during both the imaging load spike and the standby drain profile. No false low-battery flags were triggered after the first full charge-discharge cycle.
• Post-installation self-test protocol: After fitting this battery, allow the DRX-1 to complete its full power-on self-test without interrupting the boot sequence. The device runs BMS verification at startup — cutting power during this window writes a false battery fault to firmware that persists until the next clean reboot.

Device not completing boot sequence on new battery

The DRX-1 runs a BMS handshake during boot that checks cell voltage, chemistry flag, and state-of-charge before releasing the imaging system. A new cell sitting in storage can drop below the threshold the device expects at first contact — typically under 13.0V at rest. When this happens, the device halts mid-boot and displays a battery fault even though the cell is not defective. Place the battery in a compatible charger first and bring it to at least 14.4V before inserting it into the imager.

Charge indicator not reaching 100% on the first charge cycle

On the first charge after installation, the DRX-1 charge IC applies a conservative current ceiling to an uncharacterised cell — this is deliberate, not a fault. The controller has not yet mapped the cell's internal resistance profile, so it terminates the charge stage early as a safety measure. Run one complete charge-discharge-recharge cycle and the controller recalibrates its upper cut-off to the full 16.8V termination voltage. After that cycle, the indicator will reach 100% consistently.
