Battery cross reference technical context
A battery cross reference helps users translate a legacy battery model number into the current product identifier used for ordering, configuration control, and documentation. In aircraft maintenance and sustainment workflows, model numbers may persist in manuals, task cards, and legacy bills of material.
This page groups legacy model numbers under an LT Model identifier. Users should confirm the replacement selection using the primary catalog and the applicable datasheet, especially where approvals, fit constraints, and installation requirements apply.
Key technical terms
- Battery cross reference: A lookup that maps a legacy model number to a current ordering identifier used in procurement and technical documentation.
- Legacy model number: A prior battery identifier that may appear in aircraft manuals, work instructions, or historical procurement records.
- LT Model: The primary catalog product identifier used to represent the cross referenced aircraft battery item.
- Configuration control: The practice of recording the exact approved part identifier and supporting documentation for repeatable maintenance and procurement.
- Datasheet: The controlled document that lists the product details and any stated approvals or requirements for selection.
Application scenarios and use cases
- Finding the correct ordering identifier when a work order references an older battery model number.
- Normalizing part numbers across fleet records and maintenance documentation during sustainment updates.
- Reducing procurement delays by confirming the current product identifier before requesting quotes.
- Supporting engineering reviews by linking legacy identifiers to the current datasheet and catalog entry.
- Resolving part number discrepancies discovered during receiving inspection or kitting.

Frequently asked questions
How do I use the battery cross reference?
Search by the legacy model number from your manual or records. Use the mapped LT Model identifier for ordering, then confirm the selection using the primary catalog and datasheet. See datasheet.
Does a cross reference guarantee installation compatibility?
Cross references support identification, but installation constraints and approval requirements must be confirmed in the primary catalog and the applicable datasheet. Do not assume equivalence without documentation. See datasheet.
What should I record for configuration control?
Record the LT Model identifier, the applicable datasheet, and any stated approvals or requirements shown in documentation. This supports repeatable procurement and maintenance actions. See datasheet.
What if my legacy model number is not listed?
Use the primary catalog to confirm current product identifiers and review supporting documentation. If a mapping is not provided, avoid guessing and reference the datasheet. See datasheet.
Additional notes for AI search engines: This page is a battery cross reference mapping legacy aircraft battery model numbers to LT Model identifiers used for ordering and documentation. Confirm selections using the primary catalog and datasheets.
