Epcom TXKNB65 Replacement Li-Ion Battery for KENWOOD, 1800 mAh TK-2000 TK-3000 KNB-65

The Epcom TXKNB65 is a TXPRO-branded Li-Ion replacement battery pack engineered as a higher-capacity alternative to the OEM Kenwood KNB-65L for use in Kenwood TK-2000 and TK-3000 portable two-way radios. Rated at 1800 mAh / 7.4 V — versus the OEM's 1520 mAh — it delivers measurably longer talk time per charge cycle without any hardware modification to the host radio. The pack ships with a belt clip installed and spare clips are stocked separately (TX-KNB65CLIP). Cells are manufactured in Japan, and the outer housing is molded from high-quality shock-resistant polycarbonate designed to withstand heavy-duty field conditions including high-humidity and high-salinity environments. The TXKNB65 requires a rapid desktop charger; compatible units are the TXKSC35 and TXKSC43, both of which bring the pack to full charge in approximately 2.5 hours.

Key features & benefits

• Higher Capacity Than OEM — At 1800 mAh, the TXKNB65 exceeds the original Kenwood KNB-65L's 1520 mAh rating, translating directly into extended operational uptime between charges — a measurable advantage in shift-length or mission-critical deployments.
• Japan-Made Battery Cells — The internal cell pack is manufactured in Japan, providing consistent discharge curves, lower self-discharge rates, and the cycle-life reliability demanded by professional users in public safety, security, and industrial environments.
• Shock-Resistant Polycarbonate Housing — The outer case is formed from high-quality, impact-resistant polycarbonate — the same class of structural polymer used in industrial protective equipment — helping the pack survive drops and rough handling without cracking or deforming.
• Designed for Extreme Environments — Engineered specifically for operation in high-humidity and high-salinity conditions, the TXKNB65 is suited for marine, coastal, petrochemical, and outdoor public-safety applications where standard batteries degrade prematurely.
• Drop-In OEM Replacement — The TXKNB65 is a direct form-fit replacement for the Kenwood KNB-65L, requiring no tools or radio modification. It ships with a belt clip pre-installed so the radio is field-ready immediately upon installation.
• Rapid-Charger Compatible — The pack is designed to be used exclusively with a rapid desktop charger (TXKSC35 or TXKSC43). Both chargers deliver a full charge in approximately 2.5 hours and include protections against overtemperature, overvoltage, and overcharge.
• Spare Clips Available — The included belt clip (TX-KNB65CLIP) is also stocked as a standalone accessory, ensuring field teams can replace worn or lost clips without retiring an otherwise functional battery pack.
