FNB-83 Battery Replacement 7.2 Volt Ni-MH – FNB-V94 FNB-V57

Description

FNB-83 Battery Replacement 7.2 Volt Ni-MH – FNB-V94 FNB-V57

If your Yaesu / Vertex handheld radio no longer holds a charge, shuts off early on transmit, or fails a shift, the battery pack is usually the first place to check. This FNB-83 battery replacement (7.2V Ni-MH) is designed to restore dependable runtime for compatible Yaesu / Vertex Standard handheld two-way radios that use the FNB-83 form factor.

Important: “Interchangeable” listings can vary by manufacturer. While many sellers group FNB-83, FNB-V57, and FNB-V94 together, you should always confirm voltage, physical size, latch style, contact layout, and charger compatibility before ordering.

Confirm Correct Fit Before Ordering (Fast Checklist)

• Voltage: Must match exactly at 7.2V.
• Chemistry: Replace with Ni-MH when your radio/charger is designed for Ni-MH.
• Fit & Latch: Battery must lock into the radio body the same way as your original pack.
• Contacts: Compare the metal contact pattern to your original.
• Charger: Confirm your desktop/wall charger supports this battery type and form factor.

FAQ – FNB-83 Battery Replacement

Q: Is the FNB-83 interchangeable with FNB-V94 or FNB-V57?
A: Many cross-reference lists group them together, but “interchangeable” depends on your exact radio body, latch style, contact layout, and charger. Confirm the physical fit and charger compatibility before ordering.

Q: What radios use the FNB-83 battery?
A: This battery family is commonly associated with Yaesu/Vertex Standard handhelds. Yaesu lists the FNB-83 (7.2V Ni-MH) for the FT-60R. Always verify your exact model and original battery fit.

Q: Can I use a Li-ion replacement instead of Ni-MH?
A: Only if the Li-ion pack is specifically designed for your radio and your charger supports that chemistry (or the pack includes its own charging method). Using the wrong chemistry/charger combination can cause poor performance or damage.

Q: My radio shuts off when I transmit—does that mean the battery is bad?
A: Often yes. Transmit draws more current than receive, so weak cells can drop voltage under load and cause shutdown. Also check your charger, battery contacts, and overall radio condition.

Information Gain: How to Choose the Correct FNB-83 Replacement

• Match voltage first: 7.2V must match exactly.
• Match chemistry: Ni-MH packs should be charged with Ni-MH compatible chargers.
• Check the lock-in fit: Compare latch position and thickness to your original.
• Compare contacts: Even small differences in contact placement can prevent charging or power delivery.
• Runtime expectations: Higher mAh packs can run longer, but your transmit power and duty cycle matter most.
• Quick troubleshooting tip: If a “new” battery won’t charge, confirm the charger model is correct for Ni-MH and the battery style.
