M4A1 JCAD: Internal Clock Battery Fault? No Need for Alarm

An internal clock battery in the joint chemical agent detector (JCAD)—designed to last for 10 years—is used for logging accurate date and time data. When the clock battery expires, a fault occurs on the detector’s message line that flashes the words “Clock Battery Low.” However, according to TM 3-6665-456-10 (Apr 14), the JCAD will still function as a chemical detector despite the warning. 

The clock battery is a sealed system that needs to be sent in to the OEM for repair, at a cost of $1130.95 each. What’s not currently stated in the TM is that there’s no need to return the JCAD to maintenance unless retrieval of accurate data logs is required.  

Users should continue performing preventive maintenance checks and services (PMCS) following WP 0017 and Table 1 on Page 0015-9 in TM 3-6665-456-10 (Apr 14).  We’ll alert you when the TM is updated.
