Purpose & fit

This Lumapro 48H465 is a nickel-cadmium rechargeable battery rated at 4.8 volts and 300 mAh. It serves as a direct replacement for compatible emergency light kits and exit-sign fixtures that specify the listed part numbers. The JST terminal with an AMP plug connection matches the original wiring harness without adapters. Builders needing a different voltage, chemistry or capacity should select another model.

Thermals noise & power

The pack operates reliably between 32 and 113 degrees Fahrenheit, covering typical indoor and sheltered outdoor installations. Nickel-cadmium chemistry tolerates continuous trickle charging with minimal self-heating during standby. No moving parts or active cooling are present, so acoustic output is zero. A full recharge from empty requires approximately 24 hours at the specified charge current.

Sustained load behaviour

Under continuous discharge the cell maintains a stable voltage curve until near depletion, supporting the rated four-year service life in cyclic emergency-lighting duty. The 300 mAh capacity is sized for code-compliant run times rather than extended backup. Deep-cycling beyond the intended emergency duration will reduce the achievable cycle count. Yellow housing aids visual identification during routine inspections.

Questions about this item

How do I install the Lumapro 48H465 and what step do people often miss?

Connect the JST plug to the AMP terminal on compatible 6CGL3 or 6CGL4 units, ensuring the yellow housing clicks fully into place; the 3½ inch lead length requires careful routing so the connector seats without strain.

What maintenance or replacement will this 4.8V 300mAh NiCad pack need later?

Expect a rated life of four years; after that the nickel-cadmium cells lose capacity and the pack should be replaced, ideally recycled due to the Proposition 65 chemical warning.

What limit appears first during sustained use of this battery?

The maximum operating temperature of 113°F is the first hard limit; sustained loads that push the pack above this temperature will trigger thermal protection or permanent capacity loss.
