  • Reliable emergency power from 12 V 28 Ah sealed lead-acid chemistry
  • Five-year rated life supports long-term standby readiness
  • Threaded 1/4 in post or screw terminals simplify installation
  • Compatible with ELT275 and ELT125 series fixtures
  • 168-hour recharge time restores full capacity for next use

12 V 28 Ah Sealed Lead-Acid Battery for ELT275

This 12-volt sealed lead-acid battery delivers 28 Ah capacity for compatible ELT275 emergency-lighting units. It uses a threaded 1/4-inch post or screw terminal for secure connection. The black housing measures 7 3/4 inches wide, 6 1/4 inches high and 5 1/4 inches deep. Hardware is included for installation.

168-Hour Recharge Cycle and Five-Year Rated Life

A full recharge requires 168 hours, so the unit must remain on charge for a full week after discharge. The manufacturer rates the service life at five years under normal standby conditions. Threaded terminals limit use to equipment designed for 1/4-inch post or screw connections. No other terminal styles are supported.

Direct Replacement for ELT125 and Grainger 7D463

This battery replaces the ELT125 model and matches Grainger part 7D463 in compatible fixtures. The upgrade is worthwhile when the original pack reaches the end of its rated life or fails to hold charge after the 168-hour recharge window. Buyers needing higher capacity or faster recharge should verify specifications before purchasing.

Questions about this item

Should I choose the 12 V 28 Ah version or a different capacity?

This unit is a 12 V 28 Ah sealed lead-acid battery; no other capacity is offered for the ELB 1228 model.

What does the 28 Ah rating mean once the battery is installed?

It can deliver 28 amperes for one hour or a proportionally lower current for a longer period before needing recharge.

What connection standard does the threaded terminal use and what does it limit?

The 1/4 in threaded post accepts screw or bolt terminals, limiting the connection to ring or spade lugs that fit that stud size.
