Motorola CLP1010 Replacement Battery HKNN4013A 3.7V

Motorola CLP1010 / CLP446 Series — 3.7V Li-ion Replacement Battery (HKNN4013A)

This 3.7V, 1800mAh Li-ion battery replaces the HKNN4013A and compatible OEM packs across the Motorola CLP1010, CLP1040, CLP1060, and CLP446 series two-way radios. It fits the compact body of these commercial-grade radios used in retail, hospitality, and warehouse environments. Voltage and cell chemistry match OEM spec — the BMS handshake runs the same control loop as the factory pack.

• CLP series shared battery platform: The CLP1010, CLP1040, CLP1060, and CLP446 all run the same 3.7V single-cell architecture with an identical connector footprint and BMS protocol. One battery pack covers the full lineup — no adapter or modification needed.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on a CLP series dock. The BMS held steady through PTT transmit spikes and accepted the dock's charge handshake without fault on the first insertion.
• Dock contact seating on first use: If the charging dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The CLP dock requires a clean contact cycle to complete the BMS handshake before charging begins.

Why the CLP1010 drops to reduced TX power mid-shift on a new battery

The CLP1010's transmitter draws a short current spike every time PTT is pressed. If the battery's internal impedance is elevated — common in a new pack still at storage voltage — the cell voltage sags briefly under that load. The radio's power control circuit reads the sag as a low-battery condition and steps the transmitter down to protect the radio. Running two or three full charge-discharge cycles brings cell impedance down and eliminates the sag under transmit load.

Bar indicator shows one fewer bar than expected after fitting a new pack

New Li-ion cells ship at storage voltage — typically around 3.6V — not at a full 4.2V charge. The CLP series uses a simple voltage-threshold bar indicator, so a pack at storage voltage will display one bar below what a fully charged cell would show. This is not a fault with the battery. Seat the pack in the dock and complete a full charge cycle first. Once the cell reaches 4.2V, the indicator will read correctly.
