Motorola PMNN4409 IMPRES 7.4V 2150mAh Submersible Battery - Reliable

In this review of the Motorola PMNN4409 IMPRES battery the bottom line is simple: this is a dependable OEM replacement for professionals who need reliable runtime and a rugged, submersible pack for two-way radios. The reviewer found the battery delivers solid life and build quality, and it integrates cleanly with compatible XPR series radios. If you need a straightforward high-capacity Li-Ion pack that matches Motorola specifications and you value genuine replacement parts, this battery is worth considering.

Key Features

• High capacity: The 2150mAh cell provides extended runtime so users spend less time swapping batteries during long shifts or events.
• OEM construction: As an original Motorola part, it offers compatible fit and reliable communication with XPR series radios for predictable performance.
• IMPRES technology: Designed to work with IMPRES chargers and radios for optimized charging cycles and battery management.
• Submersible design: Built to withstand wet conditions so it holds up in outdoor, marine, or inclement-weather use.
• Compact form factor: The 7.4V design balances power and size, keeping radios manageable on belts or in pockets during long shifts.

Who It's For

This battery is best for technicians, first responders, security teams, and other professionals who use Motorola XPR3300, XPR3500, XPR7350, or XPR7550 series radios and need a factory-compatible, high-capacity power pack. Its submersible construction and IMPRES compatibility make it a practical choice for harsh environments and routine fleet maintenance.

Users who primarily operate consumer handheld radios or who require the absolute lightest weight pack for recreational use may look elsewhere; this battery is purpose-built for professional Motorola radios rather than general consumer devices.
