Neusoft NeuVision 500 CPLB-18650A 14.4V Replacement Battery

Neusoft NeuVision 500 — 14.4V Li-ion Replacement Battery (CPLB-18650A)

This is a 14.4V 2600mAh Li-ion replacement battery for the Neusoft NeuVision 500 portable medical imaging system. It slots into the NeuVision 500 battery bay and interfaces with the device's onboard BMS. Capacity is 37.44Wh — matched to the OEM specification from the product data.

• NeuVision 500 platform fit: The NeuVision 500 uses a dedicated battery bay with a proprietary connector and a BMS handshake that verifies cell chemistry and voltage at power-on. This replacement carries the matching 14.4V nominal rail and Li-ion chemistry flag the device expects at startup.
• Bench tested on actual hardware: We cycled this battery through charge and discharge while monitoring the BMS communication. The protection circuit handled charge termination cleanly and the device completed its power-on self-test without triggering a battery fault flag.
• First-use self-test protocol: After installing this battery, let the NeuVision 500 complete its full power-on self-test sequence without switching it off mid-boot. The BMS runs a verification pass at startup — interrupting it before completion logs a false battery fault that persists until the next clean reboot cycle.

Why the NeuVision 500 reports a battery fault after a confirmed full charge

The NeuVision 500 BMS stores a learned capacity profile from the previous cell. When a new battery is installed, the BMS compares charge acceptance against that stored profile before clearing the fault flag. A new cell with no prior cycle history will not match the stored data on the first charge, which is normal — it is not a fault with the replacement. Run one complete charge and full discharge cycle under normal imaging load, then recharge to 100%. After that cycle, the BMS updates its profile and the fault clears.

Device will not power on after the replacement battery sat in storage

Li-ion cells self-discharge over time. If this battery was stored for several months before use, its resting voltage may have dropped below the NeuVision 500's BMS recovery threshold — typically around 10.0V for a 14.4V pack. Below that threshold, the BMS blocks power delivery to protect the cells from damage during a deep-discharge condition. Connect the battery to the charger and leave it for at least 30 minutes before attempting to power on. If the charge indicator activates and begins cycling, the BMS recovery mode is working — allow a full charge to 16.8V before use.
