## Why This Recall is Important
The **HeartMate II® and HeartMate 3™ System Controllers** are lifeline devices designed to support heart function in patients with advanced heart failure. The recall is critical because the **Backup Battery Fault Alarm** can cause unnecessary concern and confusion, especially for patients and caregivers.
When the device is connected to **external power sources like 14V batteries or a Mobile Power Unit**, the Backup Battery Fault Alarm serves as an **advisory message**—not an indication of a critical system failure. However, mishandling during battery installation or replacement could potentially increase alarm frequency. Proper handling techniques and prompt action are essential to avoid unnecessary complications for users.
