Product Description & Core Advantages

✅ One Battery for the Entire CP / EP / PR / GP Entry-Level Family
Direct replacement for Motorola OEM battery NNTN4851, covering thirteen value-series models — GP3688, GP3188, CP040, CP140, CP150, CP160, CP180, CP200, CP380, PR400, EP450, XiR P3688 and GP3688D — one battery standard that unifies mixed entry-level fleets, simplifies spare-parts inventory and charging management. Plug-and-play fit, no modification required.

✅ 2200mAh Ni-MH Capacity for Full-Shift Value-Series Duty
Premium high quality long-cycle Ni-MH cells deliver stable 7.2V output and 2200mAh capacity — enough for 9-11 hours of operation under standard duty cycles (5-5-90), comfortably covering full shifts and overtime. Cadmium-free Ni-MH chemistry is environmentally friendly and tolerant of deep discharge, ideal for the daily charge-and-rotate rhythm of busy entry-level fleets.

✅ Complete Charging Safety & Zero Charger Investment
Built-in protection covers short-circuit, over-temperature, charging temperature sensing and reverse polarity — reliable cell-level safety for daily fleet operations. Robust high-impact ABS/PC composite housing and brass golden plated low-resistance contacts — anti-drop, dustproof and moisture resistant. Works with your existing Motorola CP/EP-series Ni-MH chargers (negative delta-V logic) — no new charging infrastructure required.

  • ⭐ OEM NNTN4851 Replacement — Faithfully matches original dimensions (12.12*6.00*2.11cm), drop-in fit for CP200 / PR400 / EP450 and 10 more value-series models without modification
  • ⭐ 13-Model Single-SKU Solution — One pack serves the entire CP / EP / PR / GP entry-level family, ideal for unified battery management of large fleets
  • ⭐ 2200mAh Long-Shift Runtime — 9-11 hours per shift under 5-5-90 duty cycles, comfortably covering full working days
  • ⭐ Cadmium-Free & Memory-Free Ni-MH — No toxic cadmium, recharge at any state of charge under normal cycling, environmentally friendly disposal
  • ⭐ Industrial Craftsmanship & Warranty — Brass golden plated contacts, 100% aging tested before shipment, OEM private label available, 12-month full quality warranty

Safety Cautions

  • ⚠ Do not disassemble, puncture, crush or modify the battery housing — internal cell damage may cause electrolyte leakage, overheating or fire. Stop using the battery immediately if you notice unusual heat, odor, leakage or deformation, and move it to a safe non-flammable area away from combustibles.

  • ⚠ Keep battery terminals away from metal objects such as coins, keys and jewelry to prevent accidental short-circuit. Do not expose the battery to high temperature above 60 degrees C, direct sunlight or open flame for extended periods.

  • ⚠ Only charge with a Ni-MH compatible charger using negative delta-V (or timer-based) charging logic — including your existing Motorola CP/EP-series charger for NNTN4851-type packs. Do NOT use a Li-ion CC/CV charger on this Ni-MH battery — the charging logic is completely different and may cause under-charge, overheating or permanent damage.

  • ⚠ For long-term storage, keep the pack fully charged in a cool dry place and recharge every 3 months. Dispose of spent packs at an authorized battery recycling collection point in compliance with local regulations — do not put them in household waste.

Frequently Asked Questions

Q1: Is ENH-MOT4851 fully compatible with OEM NNTN4851 and the Motorola CP200 / PR400 / EP450 radios?-
A: Yes. ENH-MOT4851 is a faithful OEM replacement for Motorola NNTN4851, with identical 12.12*6.00*2.11cm housing dimensions and a plug-and-play fit for thirteen value-series models: GP3688, GP3188, CP040, CP140, CP150, CP160, CP180, CP200, CP380, PR400, EP450, XiR P3688 and GP3688D. No modification required, and your existing CP/EP-series Ni-MH charger keeps working.
Q2: What is the difference between NNTN4851 and the NNTN4496 / NNTN4497 / NNTN4970 packs for the same radios?+
A: All four packs serve the same thirteen CP / EP / PR / GP entry-level models, but the chemistry differs: ENH-MOT4851 (this pack, OEM NNTN4851) is Ni-MH 7.2V 2200mAh — the value choice for fleets already running Ni-MH chargers; ENL-MOT4970 (OEM NNTN4970) is Li-ion 7.4V 2000mAh slim; ENC-MOT4496 (OEM NNTN4496) and ENL-MOT4497 (OEM NNTN4497) are Li-ion 7.4V 2600mAh high-capacity. Ni-MH and Li-ion packs must each be charged on their own charger type (negative delta-V vs CC/CV 8.4V) — they are not cross-compatible on the charger, so pick the chemistry that matches your existing charging infrastructure.
Q3: Can I use a Li-ion charger or a generic charger on this Ni-MH battery?+
A: No. Ni-MH cells require negative delta-V (or timer-based) charging logic, while Li-ion chargers use CC/CV (constant current / constant voltage) cutoff — the two logics are completely different. Charging this Ni-MH pack on a Li-ion CC/CV charger may cause under-charge, overheating or permanent damage. Use only a Ni-MH compatible charger such as your existing Motorola CP/EP-series charger for NNTN4851-type packs.
Q4: Will ENH-MOT4851 also fit CP185, XTS3000, GP328, GP300, MTH800 or APX / DP series models?+
A: No. ENH-MOT4851 (replacement for OEM NNTN4851) is designed ONLY for the thirteen value-series models listed above. Other Motorola generations use different battery families: the XTS3000/XTS5000 Astro series uses NTN8294, the XTS1500/XTS2500 P25 series uses NTN9815/NTN9858/NNTN7335, the APX2000/4000 series uses NNTN8128A/NNTN8129, the MOTOTRBO XPR/DP digital series uses the PMNN4407/PMNN4418 families and the PMNN4066/PMNN4077 packs, the GP328/GP340 Waris platform uses HNN4003/HNN9009/HNN9012, the GP2000/AX value series uses PMNN4046, the GP300/GTX legacy series uses HNN9628, the GP-350 uses HNN9360, the P1225 uses HNN9049, the VISAR series uses NTN7395, the MTX838/HT1000 MT-series uses NTN7143/NTN7144, the MTH800 TETRA series uses SNN5705/NNTN4655, and the CP185/CP1300/CP1600 series uses PMNN4081 — housing dimensions, voltage platform, contact arrangement and locking mechanism are NOT interchangeable across these families. The same applies across brands: Motorola packs do not fit ICOM, KENWOOD or Hytera radios and vice versa. Always check the OEM battery part number printed on your existing battery before ordering.
Q5: Do you support OEM custom labeling or bulk quantity orders?+
A: Yes, we accept OEM and ODM orders. Custom shell printing, private label, capacity variants and connector customization are all available for bulk quantity. Standard stock orders ship within 3-7 working days; OEM customized orders typically take 15-25 days lead time. Contact our sales team for exact quotation and MOQ.
