elxjar (2-Pack) 7.4V 2100mAh PMNN4434A Replacement Batteries

In this review of the elxjar (2-Pack) 7.4V 2100mAh PMNN4434A replacement batteries, the bottom line is straightforward: this pack is for radio users who need reliable backup power without fuss. The reviewer found the two-pack arrangement and the 2100mAh capacity most valuable for users who run Motorola RMU, RMV and RMM series radios through long shifts or irregular charging cycles. Fitment and compatibility are the single biggest reasons to consider these batteries, since they match several Motorola part numbers and work with common Motorola chargers.

Key Features

• Compatibility: These batteries are designed to replace PMNN4434A series packs and fit Motorola RMU2040, RMU2043 and RMU2080 radios, which reduces compatibility worries for fleet operators.
• High-capacity power: Each cell offers 7.4V and 2100mAh, giving noticeably longer runtime than typical lower-capacity replacements during extended use.
• Two-pack convenience: The package includes two rechargeable Li-ion packs, making it simple to keep a hot spare for uninterrupted operation or rotate batteries across shifts.
• Charger compatibility: These packs work with Motorola original chargers such as the PMLN6384 six-radio charger and the PMLN6394 single-radio charger, so existing charging setups continue to function.
• Multiple part number fit: Marketed as compatible with PMNN4434 PMNN4434A PMNN4434AR and PMNN4453, this reduces the need to confirm exact factory codes for many RMU/RMV/RMM series radios.

Who It's For

This two-pack is best for professionals and small teams who operate Motorola RMU, RMV or RMM series two-way radios and need dependable backup batteries for long shifts, events or remote work. It suits warehouse staff, security personnel, event managers and field crews who already use compatible Motorola chargers and want a straightforward replacement that restores runtime.

It is less appropriate for users seeking a custom battery with different voltage or capacity, or for those who require manufacturer-certified batteries for highly regulated environments; in such cases a factory-branded pack may be preferable.
