- 40% more run time than the BA-5847/U: Lithium Manganese Dioxide (Li-MnO2) chemistry outperforms the legacy Li-SO2 BA-5847/U, keeping your AN/PAS-13 or AN/PRM-34 operational longer between battery changes
- 10-year shelf life with ultra-low self-discharge: Reliable long-term storage for pre-positioned equipment and depot stockpiles without capacity loss
- Extreme temperature rated: -40°C to +72°C (-40°F to +162°F) - Stable 6V output from arctic cold to desert heat, with no warm-up lag under field conditions
- Polarized flat ribbon connector: Keyed connector prevents reverse insertion, ensuring correct polarity on every install in low-light or high-stress conditions
- Assembled in the USA; dual NSN coverage: Requisition under NSN 6135-01-455-7946 (supersedes 6135-01-090-5364) through standard DLA supply channels.
Product Description
Ultralife BA-5347/U Military Lithium Battery
The BA-5347/U is a primary (non-rechargeable) Lithium Manganese Dioxide battery designed for military night vision and thermal imaging applications. Manufactured by Ultralife and assembled in the USA, it delivers up to 40% more run time than the legacy BA-5847/U (Li-SO2) it replaces — in the same form factor, with no equipment modifications required.
Compatible Military Systems
The BA-5347/U is qualified for use with the following fielded platforms:
- Thermal imaging: AN/PAS-13 Thermal Weapon Sight
- Radio: AN/PRM-34 Radio Set
It is a direct replacement for the BA-5847/U and all BA-5347 and BA-5847 part number variants across both families.
Superior Chemistry, Same Form Factor
Where the legacy BA-5847/U uses Lithium Sulfur Dioxide (Li-SO2) chemistry, the BA-5347/U uses Lithium Manganese Dioxide (Li-MnO2) — a more energy-dense chemistry that translates directly to longer mission duration per battery. At 6.0V and 11,100mAh, it delivers stable, consistent output across the full discharge curve, with no voltage sag that could affect image quality or radio performance.
Built for Long-Term Readiness
A 10-year shelf life and extremely low self-discharge rate make the BA-5347/U well-suited for depot storage and pre-positioned equipment. Its -40°C to +72°Coperating range covers the full spectrum of operational environments, and the polarized flat ribbon connector prevents reverse insertion during rapid battery changes in the field.

Frequently Asked Questions
What is the difference between the BA-5347/U and the BA-5847/U?
The BA-5347/U uses Lithium Manganese Dioxide (Li-MnO2) chemistry, which provides up to 40% more run time than the BA-5847/U, which uses the older Lithium Sulfur Dioxide (Li-SO2) chemistry. Both share the same form factor and connector, making the BA-5347/U a direct drop-in replacement with no equipment modification needed.
Is this battery compatible with the AN/PAS-13 Thermal Weapon Sight?
Yes. The BA-5347/U is qualified for use with the AN/PAS-13 Thermal Weapon Sight (all variants) and the AN/PRM-34 Radio Set.
Is this battery rechargeable?
No. The BA-5347/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?
The current NSN is 6135-01-455-7946, which supersedes the older NSN 6135-01-090-5364. Both reference the same battery family and may appear in older equipment TMs or supply records.
What part numbers does this battery replace?
This battery replaces all variants across two part number families: BA-5347, BA-5347/U, BA-5347U, BA5347, BA5347/U, BA5347U, BA-5847, BA-5847/U, BA-5847U, BA5847, BA5847/U, and BA5847U.
How should this battery be stored?
Store in a cool, dry location away from heat sources and direct sunlight. The Li-MnO2 chemistry supports a 10-year shelf life under proper storage conditions. Keep terminals clear of conductive materials to prevent accidental discharge.
