KNB-55L Replacement Battery 2 Pack - Reliable Li-ion Power

In this review the Vineyuan 2 Pack KNB-55L replacement batteries are evaluated for users needing dependable spare power for Kenwood two-way radios. The bottom line: these factory-packed, 100% new 7.4V Li-ion cells are a practical, lower-cost replacement when the original battery weakens or as a second battery for long shifts. The single biggest reason to buy is straightforward compatibility with a wide range of Kenwood models and a compact 1500mAh capacity that balances runtime and weight for daily field use.

Key Features

• Compatibility: Works with many Kenwood models including TK-3160, TK-3360, TK-2170 and NX series radios, making it a versatile spare for mixed fleets.
• Factory New Pack: Ships as two factory-packed, never-used batteries so the customer receives fresh cells ready for first charge.
• Battery Specs: 7.4V nominal voltage and 1500mAh capacity provide a predictable runtime suitable for routine daily use and short shifts.
• Lightweight Design: At about 87g (3oz) per cell, these batteries add minimal bulk and reduce fatigue when clipped to a belt or radio holster.
• High-quality Materials: Constructed with quality components intended to match original form and function for reliable contact and fit.
• Charger Compatibility: Fits chargers that accept KNB series packs, including use with KSC-25 style bases when applicable.

Who It's For

This two-pack is aimed at professionals and hobbyists who rely on Kenwood two-way radios and need an affordable, direct replacement or backup battery. It suits building maintenance crews, event staff, security teams, and amateur radio users who rotate batteries during long shifts.

Those who need extremely long runtimes for extended multi-day operations or require manufacturer warranty support for OEM cells should consider factory OEM batteries or higher-capacity specialty packs. Casual users who rarely use their radios will still find the two-pack handy, but may prefer a single spare instead of two.

Pros & Cons

Pros

• Good compatibility across many Kenwood TK and NX series radios for flexible use.
• Fresh, factory-packed batteries ensure new condition and predictable first-use performance.

Cons

• Capacity is 1500mAh, which is moderate; users needing extended runtime may find it limiting.
• Batteries are shipped not fully charged, so they require an initial full charge before first use.
