Cameron & Co DS-CS-LFI146LS standard battery 4.8V 2000mAh Blue

SKU CH-JN7B-0YGY4

Ni-MH 4.8 V 2000 mAh replacement battery for LFI Daybrite Emergi-Lite and Light Alarms emergency lights

  • TypeMisc Battery
  • Ni-MH chemistry provides reliable rechargeable power
  • 8 V 2000 mAh capacity suits emergency lighting needs
  • 60 Wh energy rating supports extended operation
  • Compatible with Daybrite Emergi-Lite BAA48R and Light Alarms BL93NC487
  • Compact 50.30 x 28.90 x 28.80 mm design fits existing fixtures

Purpose and Compatibility

This Cameron & Co DS-CS-LFI146LS battery replaces the original power source in LFI Daybrite Emergi-Lite BAA48R and Light Alarms BL93NC487 emergency lighting units. It is built for maintenance teams and facility managers who need a direct, 100% OEM-compatible swap for the RT-146 part number. The Ni-MH pack delivers 4.8V and 2000mAh in a blue housing.

Upgrade Context

The unit serves as a like-for-like replacement when the existing 4.8V 2000mAh Ni-MH battery no longer holds a full charge or fails self-test routines. Because the specifications match the original BAA48R and BL93NC487 ratings exactly, the jump is worth it whenever the emergency light’s runtime drops below the required duration or the indicator shows a fault condition.

Fit and Alternatives

This pack suits installers who need the precise 50.30 x 28.90 x 28.80 mm form factor and the original connector layout for the listed Daybrite and Light Alarms models. Buyers whose emergency lights use a different voltage, capacity, chemistry or physical footprint should look at other options, as this battery will not fit or function correctly in those units.

Questions about this item

What are the exact dimensions of the 4.8V 2000mAh Ni-MH battery so I can check it fits the emergency light housing?

The pack measures 50.30 mm long, 28.90 mm wide and 28.80 mm high; verify the compartment in your Daybrite Emergi-Lite BAA48R or Light Alarms BL93NC487 matches these figures before ordering.

How is the replacement pack installed and what is the common mistake?

Disconnect power, open the fixture, unplug the old pack’s connector and snap in the new one observing the red-to-red and black-to-black polarity; the step often missed is forgetting to re-secure the retaining bracket so the pack cannot shift during vibration.

When will this Ni-MH pack need replacing and how can I tell?

Expect roughly three to five years of standby service; plan a swap when the monthly 30-second test shows the lamp dimming noticeably or the unit fails the annual 90-minute duration check.
