12 V 3.3 Ah SLA AGM battery

This sealed lead-acid battery uses AGM technology for maintenance-free operation in a compact design. It delivers a nominal 12 V and 3.3 Ah capacity for reliable backup power. The unit is built as a direct OEM replacement for compatible UPS and security systems. Its valve-regulated construction prevents leaks and allows installation in any orientation.

Thermals noise and power draw

AGM chemistry generates minimal heat during normal float charging and standby use. The sealed case operates silently with no moving parts or cooling fans required. Self-discharge remains low so the battery holds charge for extended periods without mains power. No active power draw occurs when the battery is idle in a backup circuit.

1.6 inch terminal spacing

The distance between terminals measures exactly 1.6 inches, which determines fit in many UPS battery compartments. Verify this spacing matches the device you are servicing before purchase. Buyers whose equipment requires a different terminal pitch or larger capacity will need an alternative model. Physical dimensions are 5.28 by 2.64 by 2.4 inches for reference.
