7.4V 2400mAh PMNN4424AR IMPRES Rechargeable Li-ion Battery - Reliable

Our review of the 7.4V 2400mAh PMNN4424AR IMPRES battery finds it best suited for professionals who need a dependable replacement for worn radio packs. It is a straightforward, compatible option for Motorola APX series radios and stands out because it pairs a high capacity 2400mAh Li-ion cell with IMPRES-compatible charging behavior, which helps maintain runtime and battery health over time. For anyone running APX2000, APX3000 or APX4000 radios in the field, this replacement offers the single biggest benefit: extended on-shift runtime without the premium price of OEM packs.

Key Features

• Capacity: The 2400mAh rating delivers longer run time between charges, which reduces battery swaps during long shifts.
• Voltage: The 7.4V Li-ion chemistry provides consistent power output that matches the original equipment design.
• Compatibility: Designed to replace PMNN4424AR and related part numbers, it fits Motorola APX2000, APX3000 and APX4000 series radios for easy replacement.
• IMPRES function: Works with IMPRES charging protocols to help preserve battery conditioning and extend overall lifecycle when used with compatible chargers.
• Included accessory: Ships with a belt clip so the pack can be mounted and used immediately without buying extra parts.

Who It's For

This battery is ideal for first responders, security teams, and field technicians who rely on Motorola APX radios and need a budget-friendly replacement that delivers near-original runtime. Its IMPRES compatibility makes it a good fit where IMPRES chargers are already in service and battery conditioning matters.

It is less suitable for users who require factory-sealed, cosmetically perfect packs; these units may show minor shell scratches from manual packing, although they are unused. Also, if a specific vendor warranty or manufacturer-only support is required, buyers should verify service options before purchase.
