In this review the elxjar KNB-45L 2-pack is assessed as a direct replacement for several Kenwood two-way radio models, aimed at users who need dependable runtime without buying OEM packs. The bottom line: this pair delivers extended run time and built-in safety for daily radio use, making it a practical choice for fleet operators, security teams, and outdoor workers who need a cost-effective replacement. The review focuses on compatibility, runtime, and safety features to help decide if it matches the original KNB-45 series batteries.

Key Features

• Wide compatibility: Works as a replacement for Kenwood TK-2200, TK-3200, TK-3300, NX-P1200, NX-P1300, NX-P1202, NX-P1302, NX-240 and NX-340 radios so users can swap it into many legacy radios without modification.
• Higher capacity: The 7.4V 2000mAh Li-ion cells provide longer run time than many older packs, reducing the need for frequent battery swaps during a shift.
• Advanced cell and management design: Uses premium cells and an advanced battery management system that helps maintain stable voltage under load for reliable radio performance.
• Durable construction: Ultrasonic sealing and an impact-resistant structure resist daily wear and the occasional drop found in field use.
• Built-in safety protection: Integrated PCM protects against short circuit, overcharge and overheat conditions to lower the risk of battery failure in routine charging and use.
• Charger compatibility notice: Fully compatible with Kenwood KSC-35 and KSC-35S chargers, which avoids compatibility surprises when replacing OEM packs.

Who It's For

The elxjar KNB-45L 2-pack is best for professionals who use Kenwood-compatible radios and need dependable spare batteries on hand, such as security teams, event staff, facilities maintenance crews, and outdoor workers. It suits anyone who values extended run time and the assurance of safety features without paying OEM prices.

It is less suitable for users who rely on charger model KSC-31, since the pack is not compatible with that charger. Buyers who demand manufacturer-branded warranty coverage or official OEM labeling may prefer to stick with original Kenwood batteries.
