Replacement battery for APX and SRX radios

The Estry APX8000XE is a 2500mAh lithium-ion pack rated at 7.4V and 18.5Wh. It matches the original specifications for Motorola APX8000XE, APX7000, APX6000XE, APX5000, APX8000 and SRX2200 portable radios. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection circuits.

Direct substitute for OEM part numbers NNTN8921

This unit replaces original batteries such as NNTN8921, NNTN8921C, PMNN4486, NNTN7038B, NNTN7035, NNTN7034B, PMNN4486A and PMNN4487A. The jump is worth it when the existing pack no longer holds a full shift charge or shows reduced transmit time.

Steady output during extended transmit cycles

Protection circuitry maintains stable voltage under continuous push-to-talk use rather than only brief bursts. ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm the pack meets safety and transport standards for professional radio fleets.

Questions about this item

What are the dimensions of this 2500mAh 7.4V battery for my APX8000XE radio?

The battery measures 86.71 x 59.83 x 41.75mm and weighs 214.1g, matching the original form factor for compatible Motorola radios.

How do I install this replacement battery and what common error should I avoid?

Align the battery rails with the radio chassis and slide upward until the latch clicks; the most common error is stopping before the latch fully engages, leaving the pack loose.

When should I replace this 18.5Wh lithium pack and how do I store it long-term?

Replace when runtime drops below 80% of new capacity; for storage longer than one month, keep at roughly 50% charge in a cool, dry place.
