Compatible Nightstick battery

The Cameron & Co DS-CS-NXP984FT is a lithium-ion replacement battery built for Nightstick models including the NSP-9842XL, NSR-9844XL and USB-578XL series. It supplies 3.4 Ah at 3.7 V for 12.58 Wh of energy in a black housing.

Thermals and power draw

Lithium-ion chemistry keeps self-discharge low and delivers steady voltage during typical handheld use. The cell fits the original compartment without modification and meets the 100 % OEM-compatible specification.

Sustained load behaviour

Under continuous drain the pack maintains output until the protection circuit cuts off at the safe lower limit. Capacity remains at 3400 mAh across repeated cycles, so runtime stays consistent for shift-length operation.

Questions about this item

How do I install the DS-CS-NXP984FT battery into my Nightstick, and what step is often missed?

Power off the device, open the battery compartment, align the 71.40 x 20.10 x 19.70 mm pack with the contacts, insert it fully until it clicks, then close the latch; the step often missed is ensuring the latch fully engages so the pack cannot shift.

What maintenance or replacement will the 3.4 Ah Li-ion pack need over time?

The 3400 mAh cell has no user-serviceable parts; expect gradual capacity loss after several hundred charge cycles, so plan to replace the pack when run-time drops below your needs.

What limit appears first during sustained use of the 3.7 V 12.58 Wh battery?

The 3400 mAh capacity sets the runtime ceiling; under continuous load the pack will reach its discharge cut-off before any thermal or current limit is hit.
