In this review the FNB-25x is evaluated as a straightforward replacement battery for owners of compatible Yaesu handheld and mobile radios. The bottom line: it is aimed at users who need a reliable, memory-free power pack that restores runtime without fuss. Our review finds the FNB-25x most valuable for technicians, amateur radio operators, and field users who want a direct substitute for the original FNB-25 or FNB-26 and prefer Ni-MH chemistry for predictable performance and simple recharging.

Key Features

• Compatibility: Fits Yaesu FT-530, FT-26, FT-76, FT-415, FT-416 and FT-816 worldwide versions, making it a convenient direct swap for several radio models.
• Capacity: 1200mAh provides a solid balance of runtime and size for typical handheld radio usage during day trips or short field operations.
• Nominated Voltage: The 7.2 volt output matches original battery specifications, avoiding underpowering or device incompatibility.
• Rechargeable Ni-MH: Memory-free Ni-MH chemistry means users do not need to fully discharge before recharging, simplifying maintenance routines.
• Recharges Easily: Accepts both plug-in wall chargers and desktop rapid chargers, so replacement is flexible with common charging accessories.
• Direct Replacement: Designed to replace original FNB-25 and FNB-26 packs without modifying the radio or battery compartment.

Who It's For

The FNB-25x is best for amateur radio operators and professionals who own one of the supported Yaesu models and need a dependable, like-for-like replacement battery.
