Compatible Replacement Battery

This lithium-polymer pack replaces the Standard Horizon FNB-115LIIS, SBR-29LIIS, SBR-45LI and SBR-45LIIS cells used in the HX400 and HX400IS radios. It delivers 3200 milliamp-hours at 7.4 volts for 23.68 watt-hours of capacity in a 131.92 by 57.40 by 32.70 millimetre form factor weighing 171.0 grams.

Upgrade From Worn Originals

The jump is worth it when the factory pack no longer holds a full day's charge or shows voltage sag under transmit load. A fresh 3200 milliamp-hour cell restores the rated runtime and the built-in protection circuitry guards against overcharge, over-discharge, over-voltage and short-circuit events that age legacy packs faster.

Drop-In Fit For Marine Handhelds

The pack slides into the existing battery compartment without modification and uses the original connector, so no wiring changes are needed. Its fully decoded chip communicates with the radio's fuel gauge exactly like the OEM unit, freeing the operator from carrying spare alkalines or bulky external packs during extended trips.

Questions about this item

Will the 131.92 x 57.40 x 32.70 mm pack fit my Standard Horizon HX400IS radio?

Yes, the 131.92 x 57.40 x 32.70 mm lithium-polymer pack matches the FNB-115LIIS form factor used by the Standard Horizon HX400 and HX400IS.

What is the installation step people most often miss when fitting this FNB-115LIIS battery?

After placing the 171.0 g pack, verify the connector is fully seated; a loose plug is the most common reason the radio will not power on.

What charging practice keeps the 7.4 V 3200 mAh cell healthy long-term?

Use the Standard Horizon charger or an approved equivalent; avoid low-quality third-party adapters and run two or three full charge-discharge cycles when the pack is new.
