BatteryJack inc. 12V 12Ah sealed lead acid battery

SKU CH-YA39-G53HE

12 V 12 Ah sealed lead-acid battery with AGM technology for UPS and backup power

  • Maintenance-free operation with AGM sealed design
  • 4-7 year expected lifespan for long-term reliability
  • Direct 100% OEM replacement fits existing equipment
  • Compact 151×98×101 mm footprint saves installation space
  • 12 V 12 Ah capacity powers UPS and security systems

Purpose-built power

This 12-volt 12-amp-hour sealed lead-acid battery uses advanced AGM technology to deliver maintenance-free energy for UPS units, emergency lighting, alarm panels and DC power systems. It is designed for buyers who need a direct drop-in replacement for existing backup installations.

Build and connections

The ABS container measures 151 by 98 by 95 millimetres with a total height of 101 millimetres including terminals, weighing approximately 4.20 kilograms. Its compact footprint fits standard battery compartments while the sealed construction prevents leaks and allows mounting in any orientation.

Upgrade path

It replaces older flooded or lower-capacity 12-volt cells in UPS, EPS, railway signalling, aircraft signalling and auto-control equipment. The jump is worth it when a 4-to-7-year design life and a 250-cycle rating at full depth of discharge reduce replacement frequency.

Questions about this item

What terminal standard does the 12 V 12 Ah sealed lead-acid battery use, and what current does it cap in practice?

The battery uses standard F2 faston terminals; the 12 Ah rating limits continuous discharge to roughly 12 A before voltage drops below usable levels.

What are the exact case dimensions and terminal height needed to fit the battery in a UPS tray?

Length 151 mm, width 98 mm, container height 95 mm, total height with terminals 101 mm.

How is the battery installed in a UPS, and which step do people often get wrong?

Slide the battery in, connect red to positive and black to negative, then secure the hold-down bracket; the common mistake is reversing the polarity leads.
