The Kenwood KNB-33LI Compatible Li-ion Battery is a premium-grade, high-capacity replacement power pack specifically engineered to deliver long-lasting, reliable performance for professional Kenwood two-way radios. Built to meet or exceed original equipment manufacturer (OEM) specifications, this battery pack is the ideal power solution for public safety officers, security personnel, industrial workers, and commercial fleet operators who rely on uninterrupted radio communications throughout long, demanding shifts.
Utilizing advanced Lithium-Ion (Li-ion) chemistry, this battery provides a nominal voltage of 7.4V and a robust 2000mAh capacity (14.8 Wh). Li-ion technology offers significant advantages over older battery chemistries, including a much higher energy-to-weight ratio for a lighter handset, and a complete absence of “memory effect.” This means you can charge the battery at any state of discharge without reducing its overall capacity or lifespan. Its lightweight, ergonomic design integrates seamlessly onto the back of your transceiver, maintaining the radio’s original balance, grip, and professional appearance.
This replacement pack is fully compatible with popular high-tier Kenwood transceivers, including the TK-2180 (VHF) and TK-3180 (UHF) handheld series. Built with durability in mind, the rugged polycarbonate casing is designed to withstand daily physical impacts, drops, vibrations, and harsh environmental conditions. Internally, the battery features gold-plated contacts to ensure maximum conductivity and corrosion resistance, alongside integrated safety circuitry that protects against overcharging, short-circuiting, and thermal overload. Keep your communications active and your team connected with this high-performance, cost-effective power upgrade.
