ENL-FNB87 7.4V 2600mAh Li-ion Rechargeable Battery for Vertex Standard VX-820 / VX-821 / VX-920 / VX-921 Two-way Radio

The ENL-FNB87 replacement battery is fully compatible with the following Vertex Standard two-way radio models:

✅ Drop-in Power for the Vertex Standard VX-820 / VX-920 Series
Direct replacement for Vertex Standard OEM battery FNB-V87LI, purpose-built for the VX-820 / VX-821 / VX-920 / VX-921 business portables. The 9.03*5.50*2.68cm housing faithfully follows the original battery dimensions — plug-and-play fit, no modification required. One battery standard covering all four models for unified fleet management across mixed VHF/UHF inventories.

✅ 2600mAh High-Capacity Li-ion for Full-Shift Duty
Premium high quality long-cycle Li-ion cells deliver stable 7.4V output and a full 2600mAh capacity — enough for 12-14 hours of operation under standard duty cycles, comfortably covering full shifts on demanding construction sites and security patrols. Li-ion chemistry has no memory effect and a low self-discharge rate, supporting frequent opportunity charging without capacity loss — ideal for back-to-back shifts and spare-battery rotation programs.

✅ 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 for harsh jobsite conditions. Works with your existing Vertex Standard VX-820/920 series Li-ion chargers (CC/CV 8.4V logic) — no new charging infrastructure required.

• ⭐ OEM FNB-V87LI Replacement — Faithfully matches original dimensions (9.03*5.50*2.68cm), drop-in fit for VX-820 / VX-821 / VX-920 / VX-921 without modification
• ⭐ 2600mAh Full-Shift Runtime — 12-14 hours of operation under standard duty cycles, keeping crews connected through back-to-back shifts
• ⭐ 5-Layer Safety Protection — Over-charge / over-discharge / over-current / temperature sensor / 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-820/920 series charger for FNB-V87LI-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.
