Product Description & Core Advantages
✅ Drop-in Power for the Vertex Standard EVX-530 Series
Direct replacement for Vertex Standard OEM battery FNB-V134LI, purpose-built for the EVX-530 / EVX-531 / EVX-534 / EVX-539 DMR digital portables. The 13.50*5.77*2.26cm housing faithfully follows the original battery dimensions — plug-and-play fit, no modification required. One battery standard covering the entire EVX-530 family for unified fleet management.
✅ 2600mAh Li-ion Energy Density for Full-Shift DMR 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 EVX-530 series Li-ion chargers (CC/CV 8.4V logic) — no new charging infrastructure required.
- ⭐ OEM FNB-V134LI Replacement — Faithfully matches original dimensions (13.50*5.77*2.26cm), drop-in fit for EVX-530 / EVX-531 / EVX-534 / EVX-539 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

Safety Cautions
⚠ 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 EVX-530 series charger for FNB-V134LI-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.
Frequently Asked Questions
Q1: Is ENL-FNB134 fully compatible with OEM FNB-V134LI and the Vertex Standard EVX-530 series radios?-
A: Yes. ENL-FNB134 is a faithful OEM replacement for Vertex Standard FNB-V134LI, with identical 13.50*5.77*2.26cm housing dimensions and a plug-and-play fit for the EVX-530, EVX-531, EVX-534 and EVX-539 DMR digital portables. No modification required, and your existing EVX-530 series Li-ion charger keeps working.
Q2: How long does the 2600mAh pack last on a single charge, and can I charge it at any time?+
A: Under standard duty cycles, the 2600mAh capacity delivers approximately 12-14 hours of operation — comfortably covering a full shift. Li-ion chemistry has no memory effect, so you can recharge at any state of charge without capacity loss, and the pack's low self-discharge rate means it holds its charge far longer in storage than Ni-CD or Ni-MH packs. Always charge with a Li-ion compatible CC/CV 8.4V charger.
Q3: Can I use my old Ni-CD / Ni-MH charger or a generic charger on this Li-ion battery?+
A: No. Li-ion cells require a dedicated CC/CV (constant current / constant voltage) 8.4V charging logic, while Ni-CD / Ni-MH chargers use negative delta-V or timer-based cutoff — the two logics are completely different. Charging this Li-ion pack on a Ni-CD / Ni-MH charger may cause over-charge, overheating or permanent damage. Use only a Li-ion compatible charger such as your existing Vertex Standard EVX-530 series charger for FNB-V134LI-type packs.
Q4: Will ENL-FNB134 also fit EVX-539 portable in another band, the Vertex VX-450 series, Motorola XPR6550, GP328 or other radio models?+
A: No. ENL-FNB134 (replacement for OEM FNB-V134LI) is designed ONLY for the Vertex Standard EVX-530 / EVX-531 / EVX-534 / EVX-539 portables listed above. Other Vertex Standard radios use different battery families (for example the VX-450 series uses FNB-V133LI), and other brands use their own families: Motorola radios use the NTN8294 (XTS Astro), NTN7143/NTN7144 (MT-series), NNTN8128A/NNTN8129 (APX), PMNN4065/PMNN4066/PMNN4077 and PMNN4407/PMNN4418 (MOTOTRBO), HNN4003/HNN9009/HNN9012 (GP328 Waris), NNTN4496/NNTN4497/NNTN4970/NNTN4851 (CP entry-level) and PMNN4071 (Mag One) families, the MTP850 TETRA uses FTN6574B, the MTH800 uses SNN5705/NNTN4655, ICOM radios use the BP- series, KENWOOD radios use the KNB- series, and Hytera radios use the BH/BL series — housing dimensions, voltage platform, contact arrangement and locking mechanism are NOT interchangeable across these families or brands. Always check the OEM battery part number printed on your existing battery before ordering.
Q5: Do you support OEM custom labeling or bulk quantity orders?+
A: Yes, we accept OEM and ODM orders. Custom shell printing, private label, capacity variants and connector customization are all available for bulk quantity. Standard stock orders ship within 3-7 working days; OEM customized orders typically take 15-25 days lead time. Contact our sales team for exact quotation and MOQ.
