BATTERY

HOW DO I INTERPRET THE HEALTH INDICATOR ON THE MOTORCRAFT BXT-65-750 BATTERY? RED OR NO COLOR(CLEAR) - WHAT ARE THE MEANINGS. I CANNOT GET AN ANSWER FROM FORD OR FORDPARTS. MY TRUCK IS A 2019 F250 LARIAT 6.2L, SRW.

From another forum:

1. Green: battery is charged and the acid level is good.
2. Yellow: Battery is partially dis-charged and the acid level is good. Re-charge the battery or drive the vehicle.
3. Red: Battery is dis-charged and the acid level is good. Charge the battery.
4. Clear and bright: Acid level is low!!! Add distilled water if possible. If not, change out the battery. Do not charge or jump start the battery!!!

While the Magic Eye ® is only located in one cell, it is still quite accurate for indicating the state of charge of all cells as they are within 95% of the same condition. If there is a catastrophic failure such as an internal short circuit, the battery would be bad, but the eye would still show green as the density of the acid is still technically correct. This is very rare.

Those indicators are only used on the factory installed batteries and are jot on service replacements. The indicators are useless in reality don't pay much attention to it. There is only two ***** in there a red and a green.

Ford diagnostic manual: "No battery with a red test-eye should be replaced. The red eye only means the battery is discharged, not necessarily defective."
