BatteryJack inc. SLA Battery 12V 18Ah UB12180 Replacement

SKU CH-DRTB-3YZXS

Sealed 12 V 18 Ah AGM battery replaces UB12180 in alarms, UPS units, scooters and mobility devices

  • 12 V 18 Ah capacity powers radio-control and telemeter gear
  • Advanced AGM technology provides deep-cycle performance
  • Sealed maintenance-free design requires no fluid checks
  • Direct replacement for UB12180 and multiple OEM models
  • Compact 7.13 x 3.00 x 6.6 in size fits tight bays

Radio Control & Telemeter Power

This 12 V 18 Ah sealed lead-acid battery is built as a direct replacement for the UB12180 in radio control, communications and telemeter equipment. Advanced AGM construction makes it maintenance-free and suitable for deep-cycle use across scooters, mobility chairs, gate operators and backup-power systems.

AGM Deep-Cycle Limits

The AGM chemistry delivers a 4-to-7-year design life but cannot accept rapid charge rates or sustained high-current draws beyond its 18 Ah rating. Terminal voltage drops under heavy load, so equipment that demands instant peak current may see reduced run-time compared with higher-capacity packs.

Fit & Compatibility Check

Verify that your device accepts the 7.13 in × 3.00 in × 6.6 in footprint and 12.5 lb weight before ordering. Confirm the nut-and-bolt terminal style matches the original wiring harness and that the charging circuit is calibrated for a 12 V AGM cell rather than gel or flooded chemistry.

Questions about this item

Should I choose this 18Ah battery or one of the listed 15Ah, 16Ah, 17Ah or 19Ah alternatives?

This model is an 18Ah unit; the supplier lists it as a direct replacement for 15Ah, 16Ah, 17Ah, 18Ah and 19Ah batteries, so it covers all those capacities.

What does the 18Ah rating deliver when the battery is installed in a UPS or scooter?

The 18Ah rating means the battery can supply 18 amps for one hour or proportionally less current for longer periods, giving typical deep-cycle run time for UPS backup, scooters or alarm panels.

How do the nut-and-bolt terminals connect, and what current can they handle?

The battery uses nut-and-bolt terminals for a secure ring-lug connection; they are rated for the full 18Ah deep-cycle current the AGM cell can deliver.
