Acuity Lithonia ELB 2P41P2N Battery Kit

This nickel-cadmium battery kit delivers 2.4 V and 1.2 mAh capacity for compatible emergency lighting units. It is intended for maintenance teams replacing depleted cells in existing fixtures. The pack includes a wire harness for direct connection. Buyers who need higher capacity or a different voltage should verify specifications before ordering.

Installation and Common Issues

The AMP terminal with 643813-2 connection mates with the fixture's existing wiring harness. Polarity must be observed during installation to avoid damage. A full recharge requires 72 hr before the unit returns to rated performance. Installers who skip the conditioning cycle often report premature capacity loss.

Nickel-Cadmium Chemistry Limits

The 1.2 mAh rating supports only low-current emergency loads for the rated 7 yr service life. Memory effect can reduce usable capacity if the pack is not periodically deep-cycled. Self-discharge during long storage may require a full recharge before deployment. This chemistry is unsuitable for high-drain or frequent-cycling applications.

Questions about this item

How can I verify the ELB 2P41P2N battery is charging correctly after installation?

After connecting the included wire harness to the AMP terminal, allow the full 72-hour recharge time; the battery should then deliver its rated 2.4 V output for the LQC series emergency lighting unit.

What comes with the ELB 2P41P2N kit and what must be sourced separately?

The kit includes the nickel-cadmium battery pack with 643813-2 terminal connection and a wire harness; the compatible LQC series emergency lighting housing (such as model LQC 1 G EL N) is sold separately.

Which capacity version of the ELB 2P41P2N should I choose for my LQC fixture?

This model provides a 1.2 mAh capacity at 2.4 V and is the direct replacement specified for LQC series units; no alternative capacities are offered for this part number.
