6V 1.2Ah SLA battery for UPS

This sealed lead-acid battery uses AGM technology to deliver 6 volts and 1.2 ampere-hours of capacity. It is designed as a direct replacement for backup power units that require a PS-612 or UB613 form factor. The maintenance-free construction suits server rooms and network closets where regular servicing is impractical.

Replaces 1.3Ah or 1.4Ah units when space is tight

The physical footprint measures 3.82 inches long, 2.05 inches high and 0.94 inches wide, matching the DMZ12 outline. Swapping a higher-capacity pack that exceeds these dimensions can prevent the tray from closing or the terminal cover from fitting. The jump is worth it only when the existing cavity cannot accept a larger block.

AGM chemistry limits deep-cycle use

The 4-to-7-year design life assumes float service at moderate temperature; repeated full discharges will shorten that span considerably. The 100 percent OEM replacement claim covers electrical compatibility, not an extended cycle count. Buyers who need daily cycling or rapid recharge should look at alternative chemistries instead.
