VLX/ACM-VLX/EXP/AXM operation and maintenance
The onboard lithium coin-cell battery provides power for the real-time clock and
for battery-backed SRAM when 24 VAC power is unavailable.
For best results, replace the coin-cell battery every three years. Standby battery
life is approximately 10 years, with 1.5 years of cumulative backup capability.
Battery life varies depending on application.
