Charter Kontron Vitalogik 4500 Compatible Battery 14.8V 5200mAh

Charter Kontron Vitalogik 4500 — 14.8V Li-ion Replacement Battery (TSGLIIO100298)

This is a 14.8V, 5200mAh lithium-ion replacement battery for the Charter Kontron Vitalogik 4500 patient monitoring system. It fits the Vitalogik 4500 directly, matching the OEM part number TSGLIIO100298. The Vitalogik 4500 monitors heart rate, SpO2, and blood pressure at the bedside and during patient transport.

• Vitalogik 4500 platform fit: The Vitalogik 4500 runs a proprietary BMS handshake that authenticates cell chemistry at 14.8V nominal. This replacement uses matched lithium-ion cells at the same voltage rail and connector pinout, so the BMS handshake completes without fault codes.
• Bench tested on actual hardware: We cycled this battery through the Vitalogik 4500 power-on self-test sequence. The BMS reached full charge acceptance and cleared all battery status flags within two full charge-discharge cycles. No thermal events or cutoff trips were recorded.
• Post-installation self-test protocol: After fitting this battery, allow the Vitalogik 4500 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence writes a false battery fault to memory that persists until the next clean reboot.

Device not completing boot sequence after battery swap

The Vitalogik 4500 runs a multi-stage boot sequence that includes a battery authentication check before the monitoring software loads. A new cell that hasn't completed its first full charge cycle may present a state-of-charge reading the BMS flags as insufficient for boot clearance. This is a threshold check, not a hardware fault. Charge the battery fully before the first install, then allow the device to boot without interruption — the sequence completes once the BMS logs an authenticated full-charge event.

Charge indicator not reaching 100% on first charge

On the first charge cycle, the Vitalogik 4500's charge IC applies a conservative current limit to new lithium-ion cells while it profiles internal resistance. The display may hold at 95–99% for an extended period before the final trickle phase completes. This is normal behaviour and not a sign of a defective cell. Let the charge cycle finish uninterrupted — the indicator will reach 100% and the charge IC will log the full-capacity baseline for future cycles.
