Product Description
Saft BA-5800/U Military GPS Battery
The BA-5800/U is a primary (non-rechargeable) Lithium Sulfur Dioxide (Li-SO2) battery manufactured by Saft for use in military GPS receivers, position-finding systems, and compatible detection equipment. Assembled in the USA, it delivers stable 5.8V output across an extreme temperature range in a tall cylindrical form factor sized specifically for PLGR and related devices.
Compatible Military Systems
The BA-5800/U is qualified for use with the following fielded military platforms:
- GPS receivers: AN/PSN-11 PLGR (Precise Lightweight GPS Receiver), AN/PSN-10, PSN-8, PSN-11
- Position reporting: CP-1995
- Detection equipment: CAM (Chemical Agent Monitor)
It is compatible with all BA-5800 and BA-5800A/U part number variants via the same 2 pressure-type contact interface.
Form Factor and Installation
The BA-5800/U uses a tall, narrow cylindrical form factor — 1.33" diameter × 5.04" tall — with dual pressure-type end contacts. This geometry is specific to the PLGR battery compartment and related devices. Verify dimensional compatibility against your equipment's technical manual before ordering if you are unsure of your device configuration.
Built for Long-Term Readiness
A 6-year shelf life and ultra-low self-discharge rate support depot stockpiling and pre-positioned equipment programs. Stable voltage across -60°C to +71°C ensures reliable GPS and position-reporting performance across the full range of operational environments. The built-in discharge activation switch enables safe, compliant field disposal without external equipment.

Frequently Asked Questions
What is the PLGR and what battery does it use?
The PLGR (Precise Lightweight GPS Receiver), designated AN/PSN-11, is a handheld military GPS device used for precise position determination. It uses the BA-5800/U primary lithium battery. Earlier position-finding devices in the same family — the AN/PSN-10, PSN-8, and CP-1995 — also use this battery.
Why does this battery have two different Federal Supply Class codes in its NATO NSNs?
Most batteries are cataloged under FSC 6135 (batteries, primary). However, NATO stock number 6665-99-760-9742 uses FSC 6665, which covers detection and alarm instruments. This cross-cataloging exists because one of the BA-5800/U's compatible devices — the Chemical Agent Monitor (CAM) — falls under FSC 6665, and the battery was cross-referenced into that supply class for procurement convenience. Both NSNs reference the same BA-5800/U battery.
What is the difference between the BA-5800/U and the BA-5800A/U?
The BA-5800/U and BA-5800A/U are cross-referenced as compatible replacements for the same applications. Both designations use the same form factor and contact interface. If your technical manual or supply record references either variant, the BA-5800/U will serve as the correct replacement.
Is this battery rechargeable?
No. The BA-5800/U is a primary (non-rechargeable) lithium battery. It must be replaced once depleted and should never be connected to a charger.
What NSNs can be used to requisition this battery?
U.S. procurement: 6135-01-440-7774. NATO procurement: 6135-99-798-9851 or 6665-99-760-9742 (the latter cataloged under FSC 6665 for CAM-related procurement).
What does the discharge activation switch do?
The built-in discharge activation switch allows the battery to be safely and fully discharged prior to disposal in compliance with military battery handling 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 6-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.
