Centenex Electronics DS-CS-MTK144TW two-way radio battery 7.5V 2500mAh Ni-MH black

SKU CH-S02W-Z29CW

Ni-MH two-way radio battery delivering 7.5 V and 2.5 Ah for compatible Motorola models

  • Product typeAccessories (Battery)
  • Replaces original Motorola batteries across 11 compatible models
  • Delivers 7.5V 2500mAh capacity for extended talk time
  • Ni-MH chemistry avoids memory effect for reliable recharging
  • Compact 153.00 x 59.00 x 20.00 mm profile fits existing radio housings
  • 100% OEM compatible with NTN7143 and NTN7144 part numbers

Replacement battery for Motorola radios

This Centenex Electronics Ni-MH pack replaces Motorola part numbers NTN7143, NTN7144 and FuG11b across models such as GP1200, GP2010, HT1000, MT2000 and MTX series. It delivers 7.5 V and 2500 mAh in a black housing measuring 153.00 x 59.00 x 20.00 mm. The cell chemistry suits users who need a direct drop-in power source for legacy two-way units.

Fits existing battery compartments

The pack slides into the same cavity used by the original Motorola batteries, so no chassis modification or adapter is required. Its 18.75 Wh capacity supports extended shift operation without adding bulk. Builders who need a higher-voltage platform or a different form factor will not be served by this specific replacement.

Steady output during long transmissions

Ni-MH chemistry maintains a stable voltage curve across prolonged push-to-talk cycles, reducing the voltage sag seen in short bursts. The 2.5 Ah rating sustains receive and transmit periods typical of marine or commercial duty. Users expecting rapid-charge capability or lithium-style energy density should consider alternative chemistries not offered here.

Questions about this item

How long will the 2500 mAh Ni-MH pack run before voltage drops under continuous transmit?

The 7.5 V 2500 mAh cell stores 18.75 Wh; actual run-time depends on the radio's transmit duty cycle and power setting.

Does the pack get hot or draw extra current during all-day use?

Ni-MH chemistry runs warm under heavy load; the radio's own thermal management handles heat and current draw.

Which Motorola radios accept this battery without an adapter?

Fits GP1200, GP2010, GP2013, GP900, HT1000, HT6000, JT1000, MT2000, MT2100, MTS2000, MTS2010, MTS2013, MTX8000, MTX9000, MTZ2000, PTX1200 and HAT100 models.
