ENC-FNB57 7.2V 1100mAh Ni-CD Rechargeable Battery for Vertex Standard VX-160 / VX-170 / VX-410 / FT-60R Two-way Radio

The ENC-FNB57 replacement battery is fully compatible with the following Vertex Standard / Yaesu two-way radio models (30+ models, one pack for the whole fleet):

✅ One Pack for 30+ Vertex Standard / Yaesu Handhelds
Direct replacement for Vertex Standard OEM battery FNB-V57, purpose-built for an exceptionally broad family — VX-110 through VX-246 consumer/business portables, the VX-400/410/418/420/428 business series, VX-800V/U and VX-900, the FT-60R amateur handheld, VXA-200/VXA-300 aviation portables and HX270/HX370S/HX500S/HX600S marine handhelds. The 9.50*5.79*1.60cm housing faithfully follows the original battery dimensions — plug-and-play fit, no modification required. One battery standard covering the entire mixed legacy fleet for unified procurement and management.

✅ Proven Ni-CD Economy for Large Rotation Pools
Premium high quality long-cycle Ni-CD cells deliver stable 7.2V output and a dependable 1100mAh capacity — enough for 5-7 hours of operation under standard duty cycles. Ni-CD chemistry is the classic fleet economics choice: it tolerates fast charging and deep discharge, performs reliably down to -20 degrees C in cold storage yards and winter jobsites, and offers the lowest cost per charge cycle of any chemistry — ideal for large spare-battery rotation pools on existing Ni-CD charging infrastructure.

✅ Full Protection Suite & Zero Charger Investment
Integrated protection covers short-circuit, over-temperature, charging temperature sensing and reverse polarity — complete 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 Ni-CD chargers (negative delta-V logic) — no new charging infrastructure required.

• ⚠ 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 electrolyte leakage, 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 Ni-CD compatible charger using negative delta-V charging logic — including your existing Vertex Standard charger for FNB-V57-type packs. Do NOT use a Li-ion CC/CV 8.4V charger on this Ni-CD battery — the charging logic is completely different and may cause over-charge, overheating or permanent damage.

• ⚠ This product contains cadmium. Dispose of spent packs only at an authorized battery recycling collection point in compliance with local regulations on nickel-cadmium battery handling — do not put them in household waste or incinerate.
