APX4000XH — P25 with 4,100mAh Battery and 42-Hour Runtime at 390g
The marathon runner of the APX line: 4,100mAh extended battery delivering 42 hours of P25 Phase 2 runtime — three-plus standard shifts on one charge — in a 390g chassis. Built for extended operations where resupply points are hours away: wildland fire suppression, border patrol, disaster response, and long-haul convoy security. The 42-hour envelope eliminates mid-mission battery swaps and the spare-battery logistics train that smaller-capacity fleets must carry, while retaining the full APX ruggedness and encryption posture.
MTP6750 — TETRA with Dual GPS + Dead Reckoning at 19 Hours
The positioning specialist of the TETRA line: dual GPS plus dead-reckoning sensors that keep location tracking alive inside tunnels, underground parking, and dense urban canyons where satellite lock is lost. IP67 rated with 19-hour runtime. For utilities, metro transit, and mining operations whose dispatchers need continuous location visibility — the dead-reckoning engine bridges GPS gaps so a worker entering a tunnel does not vanish from the dispatch map, a capability a battery-first P25 radio cannot match regardless of its runtime.
