Motorola MTP3150

Battery replacement

The original part code for the original battery is NNTN8023B.

You can find working replacements fairly easily on Aliexpress, for instance:

• 2900mAh NNTN8023, NNTN8023A, NNTN8023AC Battery for Motorola MTP3100 MTP3150 MTP3250 Two Way Radios Battery with Belt Clip

From what I've seen, MTP3XXX batteries should be compatible with this device.
