ENL-FNB113 7.4V 2600mAh Li-ion Rechargeable Battery for Vertex Standard VX-450 / VX-451 / VX-454 / VX-459 Two-way Radio

The ENL-FNB113 replacement battery is fully compatible with the following Vertex Standard two-way radio models:

✅ Drop-in Power for the Vertex Standard VX-450 Series
Direct replacement for Vertex Standard OEM battery FNB-V113LI, purpose-built for the VX-450 / VX-451 / VX-454 / VX-459 compact portables. The 10.37*5.80*2.37cm housing faithfully follows the original battery dimensions — plug-and-play fit, no modification required. One battery standard covering the entire VX-450 family for unified fleet management.

✅ 2600mAh Li-ion Energy Density for Full-Shift Duty
Premium high quality long-cycle Li-ion cells deliver stable 7.4V output and 2600mAh capacity — enough for 12-14 hours of operation under standard duty cycles, comfortably covering full shifts. Li-ion chemistry has no memory effect and a low self-discharge rate, supporting frequent opportunity charging without capacity loss, with the highest energy density of any chemistry at this size.

✅ 5-Layer Protection & Zero Charger Investment
Built-in protection circuitry guards against over-charge, over-discharge, over-current, over-temperature and reverse polarity — complete cell-level safety for daily operations. Robust high-impact ABS/PC composite housing and brass golden plated low-resistance contacts — anti-drop, dustproof and moisture resistant. Works with your existing Vertex Standard VX-450 series Li-ion chargers (CC/CV 8.4V logic) — no new charging infrastructure required.

• ⭐ OEM FNB-V113LI Replacement — Faithfully matches original dimensions (10.37*5.80*2.37cm), drop-in fit for VX-450 / VX-451 / VX-454 / VX-459 without modification

• ⭐ 2600mAh Full-Shift Runtime — 12-14 hours of operation under standard duty cycles, keeping teams connected through back-to-back shifts

• ⭐ 5-Layer Safety Protection — Over-charge / over-discharge / over-current / over-temperature / reverse polarity protection integrated for daily reliability

• ⭐ Memory-Free & Low Self-Discharge Li-ion — No memory effect, recharge at any state of charge, holds charge far longer in storage than Ni-CD / Ni-MH packs

• ⭐ Industrial Craftsmanship & Warranty — Brass golden plated contacts, 100% aging tested before shipment, OEM private label available, 12-month full quality warranty

• ⚠ Do not disassemble, puncture, crush or modify the battery housing — internal cell damage may cause electrolyte leakage, overheating or fire. Stop using the battery immediately if you notice swelling, unusual heat, odor or deformation, and move it to a safe non-flammable area away from combustibles.

• ⚠ Keep battery terminals away from metal objects such as coins, keys and jewelry to prevent accidental short-circuit. Do not expose the battery to high temperature above 60 degrees C, direct sunlight or open flame for extended periods.

• ⚠ Only charge with a Li-ion compatible charger using CC/CV 8.4V charging logic — including your existing Vertex Standard VX-450 series charger for FNB-V113LI-type packs. Do NOT use a Ni-CD / Ni-MH negative delta-V charger on this Li-ion battery — the charging logic is completely different and may cause over-charge, overheating or permanent damage.

• ⚠ For long-term storage, keep the pack at roughly half charge in a cool dry place. Dispose of spent packs at an authorized battery recycling collection point in compliance with local regulations — do not put them in household waste.
