Improved Warranty and IP Rating
Motorola Solutions recently started shipping IMPRES 2 batteries for the APX 6000, APX 7000, and APX 8000 series radios. The new IMPRES 2 batteries are Li-ion chemistry and are more rugged with a IP68 submersibility rating. Battery capacity ratings are larger too but Motorola changed to “typical” from “minimum” that may not result in better performance. There are 3 housing sizes and all IMPRES 2 batteries include a 24 month capacity warranty when used with an IMPRES charger.The PMNN4485, PMNN4486, PMNN4487, and PMNN4494 outlined in blue above are not IS (intrinsically-safe) and can be used with APX 8000, 7000, and 6000. The NNTN8930 and NNTN8921 outlined in yellow are IS (Div 1 & 2) for only APX 6000, 7000. The PMNN4504 and PMNN4505 outlined in red are designed for APX8000XE IS radios for Division 2 only.
New APX IMPRES 2 Chargers Include USB Charging Ports
Motorola has introduced new IMPRES 2 chargers for the new APX batteries. The NNTN8860 single unit AC charger is more energy efficient and includes two USB charging ports. There is a switch to disable the condition/calibration features when needed.
There is also a multi-unit NNTN8844 charger that has six APX radio pockets and six more USB charging ports. Each pocket also has a display for reading battery data. This charger is designed for long term battery storage and has a switch for maintaining batteries at 50% and 75% capacity levels. The first pocket provides additional battery data including IMPRES vs. non- IMPRES charge cycles, potential, rated, and initial capacity.
