Replacement Battery for EDAN ECG Models

The KingSener TWSLB-005 is a 14.8V 2500mAh 37Wh lithium-ion battery designed as a direct replacement for EDAN SE-1, SE-100, SE-1200 and SE-1201 electrocardiograph devices. It matches the original battery dimensions for straightforward installation without modification.

Pre-Use Conditioning and Storage Guidance

The supplier advises performing two to three full charge and discharge cycles at low current to reach rated capacity. Storing the pack above 80% charge and avoiding prolonged adapter connection while in use helps preserve cell health over time.

Li-ion Chemistry and Voltage Constraints

The 14.8V nominal output suits equipment designed for this specific voltage rail; it cannot power systems requiring different voltages. Lithium-ion cells degrade if exposed to high heat, humidity, deep discharge or physical damage, limiting service life in harsh environments.

Questions about this item

Will the 2500mAh capacity need replacing after a certain number of charge cycles?

The lithium-ion cells are rated to hold a full charge that meets or exceeds the 37Wh design capacity; regular full charge and discharge cycles every few months help maintain that level.

What is the first limit reached during continuous discharge at 14.8V?

The 2500mAh rating defines the total charge available, so runtime ends when that capacity is depleted.

How much heat does the battery produce when powering an ECG device all day?

Normal operation stays within safe thermal limits; avoid hot or humid storage and do not leave the charger connected while the battery is in use.
