Product Description
Saft BA-5598/U Military Lithium Battery
The BA-5598/U is a primary (non-rechargeable) Lithium Sulfur Dioxide (Li-SO2) battery manufactured by Saft for use in the PRC-25, PRC-77, PRC-1077, and PRC-1099 radio families. Assembled in the USA, it is the current lithium replacement for the legacy BA-386/U, BA-3386/U, and BA-4386/U batteries — delivering stable 14.4V output across the widest operating temperature range of any battery in this catalog.
Compatible Military Radios
The BA-5598/U is qualified for use with the following platforms:
- AN/PRC-25 — Vietnam-era manpack radio, still maintained in reserve and surplus inventories
- AN/PRC-77 — successor to the PRC-25, widely fielded through the 1970s–1990s
- PRC-1077
- PRC-1099
It replaces the BA-386/U, BA-3386/U, and BA-4386/U batteries across all compatible platforms via the same 6-position connector interface.
Extreme Temperature Performance
The BA-5598/U is rated for -60°C to +85°C (-76°F to +185°F) — the broadest operating temperature range in this battery catalog. The +85°C ceiling is particularly relevant for desert and vehicle-mounted applications where battery compartment temperatures can exceed ambient air temperature significantly.
Built for Long-Term Readiness
A 10-year shelf life and ultra-low self-discharge rate support depot stockpiling and pre-positioned equipment programs. The built-in discharge activation switch allows safe, compliant field disposal in accordance with military battery handling requirements — no external discharge equipment needed.

Frequently Asked Questions
What radios use the BA-5598/U battery?
The BA-5598/U is designed for the PRC-25, PRC-77, PRC-1077, and PRC-1099 radio families. It replaces the BA-386/U, BA-3386/U, and BA-4386/U batteries used in these platforms. Consult your equipment's technical manual to confirm battery position and installation procedure for your specific configuration.
What is the difference between NSN 6135-01-034-2239 and NSN 6135-01-447-5081?
These two NSNs refer to different packaging quantities of the same battery. 6135-01-034-2239 is the NSN for a single BA-5598/U battery. 6135-01-447-5081 is the NSN for a pack of four BA-5598/U batteries. This listing is sold and priced as a single battery under NSN 6135-01-034-2239.
What batteries does the BA-5598/U replace?
The BA-5598/U is a direct replacement for the BA-386/U, BA-3386/U, and BA-4386/U — the legacy battery designations for the PRC-25 and PRC-77 radio families. It uses the same 6-position connector and requires no modification to the radio.
Is this battery rechargeable?
No. The BA-5598/U is a primary (non-rechargeable) lithium battery. It must be replaced once depleted and should never be connected to a charger.
What does the discharge activation switch do?
The built-in discharge activation switch allows the battery to be fully discharged prior to disposal in compliance with military battery handling and disposal requirements, without the need for external discharge equipment in the field.
How should this battery be stored?
Store in a cool, dry location away from heat sources and direct sunlight. The Li-SO2 chemistry supports a 10-year shelf life under proper storage conditions. Keep terminals protected from conductive materials. Li-SO2 batteries may vent sulfur dioxide gas if damaged or improperly handled — follow applicable handling protocols.
