Mortara ELI 250 ECG Machine Maintenance-free Sealed Lead-acid Battery DJW12-2.3 12V 2.5AH
Mortara ELI 250 ECG Machine Maintenance-free Sealed Lead-acid Battery DJW12-2.3 12V 2.5AH
■ Product Describe
Maintenance-free Sealed Lead-acid Battery DJW12-2.3 12V 2.5AH for Mortara ELI 250 ECG Machine is a high-reliability backup power supply designed for medical equipment. It uses advanced valve-regulated lead-acid (VRLA) technology to ensure safe and stable power supply in clinical environments. DJW12-2.3 battery is the built-in backup power supply of ELI 250 ECG machine. It is an AGM (absorbent glass mat) type sealed lead-acid battery. It is not easy to leak electrolyte during use, so you don't need to spend a lot of time maintaining the battery, saving costs.
■ Product Picture
■ Functions
1. Main power interruption support
Automatically supplies power when the external AC power is disconnected to maintain the operation of the device (such as ambulance transfer or hospital power outage scenarios), ensuring that ECG collection is not interrupted.
2. Mobile medical support
Supports mobile use of the device in wards, outpatient clinics and other scenarios, and the battery life meets the needs of a single examination.
3. Charging management
Floating charge (2.25V/cell) is achieved through the motherboard intelligent charging circuit, and it automatically switches to trickle charging after full charge to extend the battery life.
When the external power supply is connected, the battery automatically switches to charging and storage mode. When the external power supply is disconnected, the battery automatically powers the device. The conversion time is less than 1 second, reducing the power outage of the device due to power supply problems and ensuring the continuity of the monitoring process.
4. Safety in use
The battery has a built-in 4-fold safety circuit setting, including overcharge, over-discharge, overcurrent and short-circuit protection, to ensure the safety of the battery charging and discharging process and the battery life.

■ Precautions for use
1. Charging management
When the device prompts "low battery" (displayed on the display), the battery should be charged immediately to prevent deep discharge from causing irreversible loss of battery capacity and affecting the battery life.
Also, it is necessary to pay attention to temperature compensation. For every deviation of the ambient temperature from 25°C±10°C, the charging voltage needs to be adjusted (±3mV per cell) to prevent overcharging or undercharging.
2. Maintenance specifications
For daily cleaning, please use a dry cloth to wipe the surface of the battery. Ammonia-containing cleaners are prohibited to avoid corrosion of the battery interface.
Check the battery health status (such as internal resistance, capacity) through the device menu every quarter, check regularly, and replace it in time if abnormalities are found.
3. Environmental control
When the battery is not used for a long time, please store it after fully charging it, and it needs regular maintenance. Recharge it once every 3 months to ensure that the battery power is above 80% to prevent sulfide.
Stay away from MRI equipment or high-frequency electric knife (≥1 meter) to avoid magnetic field interference with battery performance.
