Replacement Battery for Motorola Two-Way Radios

This 1700mAh 3.7V lithium-ion cell replaces Motorola part numbers NNTN4655, NNTN4655B, NNTN6922A and NNTN6923A. It fits the DTR410, DTR520, DTR550, DTR620, DTR650, MTH650 and MTH800 models. The pack includes a fully decoded chip that communicates with the radio exactly like the original equipment battery. Buyers who need a higher-capacity pack for longer shifts should look elsewhere.

Thermals Noise and Power Draw

The battery delivers 6.29Wh at a nominal 3.7 volts and weighs 40.0g. Internal protection circuitry guards against overcharge, over-discharge, over-voltage and short-circuit events during normal operation. No active cooling or fan is present, so the cell runs silently in the handset. The supplier notes that peak capacity is reached after two or three full charge cycles.

Build Quality and Daily Use

Dimensions are 57.70 x 36.00 x 12.30mm, matching the OEM form factor for a direct drop-in fit. The pack ships in shock-absorbing foam to protect the cells during transit. Installation is straightforward, with many reference videos available online, and the connector aligns with the radio's battery rails without modification. The product carries ISO9001, RoHS and CE certifications.

Questions about this item

How do I install the Cameron Sino 1700mAh battery in my Motorola DTR650, and what is the step people get wrong?

Slide the pack into the radio chassis until the latch clicks, then verify the connector is fully seated; the most common error is leaving the connector slightly offset, which prevents the radio from powering on.

What maintenance or replacement will the 1700mAh 3.7V pack need later?

No scheduled maintenance is required; when run time noticeably shortens after many charge cycles, replace the pack with another Cameron Sino unit matching part numbers NNTN4655, NNTN4655B or NNTN6922A.

What limit shows up first on the 1700mAh pack during sustained transmit use on a Motorola MTH800?

The 6.29 Wh capacity limits continuous transmit time; heavy push-to-talk duty cycles will deplete the charge faster than standby, requiring a recharge or spare pack.
