Thermals noise and power draw in normal use

Sealed lead-acid chemistry produces no fan noise and negligible heat during float charge or standby. Self-discharge stays low so the UPS draws minimal AC power to keep the bank topped up. Under discharge the cells deliver steady current without thermal spikes that would stress the host electronics. No active cooling is required in typical rack or tower environments.
