For sale Used Original Biocare FM-801 Fetal Monitor Battery HYLB-293 14.8V 2000mAh 29.6Wh
This battery is a salvaged battery from the Biocare FM-801 Fetal Monitor. It is an original factory battery, but it has been used and is still in good condition. This battery can output a stable voltage of 14.8V, ensuring the accuracy and validity of the monitoring data during the power supply process. It also has good battery life, allowing the device to be used temporarily without a fixed power source. In addition, it can operate normally in a temperature range of -10℃ to 50℃, making it a highly adaptable battery.
1. Battery Life and Charging
Charging time is approximately 3-4 hours (using the original charger). It supports fast charging and automatically switches to trickle charging later in the charging process to prevent overcharging. It has a low self-discharge rate in standby mode and retains over 85% of its charge even after one month of inactivity.
2. Medical-Grade Safety Design
The battery incorporates a quadruple protection chip against overcharge, over-discharge, short circuit, and over-temperature, preventing battery bulging, leakage, or fire, meeting high clinical safety requirements.
3. Physical Characteristics
The casing is made of flame-retardant ABS material, measuring approximately 150×70×25mm and weighing approximately 300g. Installation does not affect device portability. The terminal interfaces feature a foolproof design to prevent damage from incorrect insertion.

Key Usage Points
1. Charging Timing: Charge immediately when the monitor indicates "low battery." Power outages during monitoring may cause you to miss abnormal fetal heart sounds; a spare battery is recommended.
2. Cleaning and Storage Guidelines: The maternity ward environment requires frequent disinfection. When cleaning the battery, only wipe the casing with 75% alcohol; do not soak it. Store the battery separately from the monitor to avoid contamination of the interface by postpartum secretions or amniotic fluid.
3. Capacity Decay Warning: When the battery life drops below 3 hours on a full charge, or when a low battery warning appears quickly after charging, it indicates severe capacity decay and the battery needs immediate replacement.
