Confirm the current model specification and applicable test conditions before system approval. Charging, discharging and storage limits are separate requirements.
Check the replacement reference and terminal arrangement
The source catalogue associates this model with the YT4L reference. Confirm case fit, polarity, terminal dimensions and charging-system limits before approving a replacement. Engine displacement alone does not establish compatibility. Request the current pack-capacity and energy specification with your sample proposal.
What to include in an enquiry
Include this model, your application, quantity, destination and required delivery date. For a starter replacement, include the original battery reference and vehicle details. For a storage system, include inverter information, load power and backup-duration requirements.
