Ford Mustang (1999-2004) Service Manual: Battery and Cables

Vehicles are equipped with a 12 volt maintenance-free battery that contains a built-in hydrometer. The hydrometer eye indication is as follows:

  • A green dot means the battery is OK.
  • A yellow dot, red dot, or when the green dot is not visible, means the battery needs to be charged.

WARNING: Batteries normally produce explosive gases which can cause personal injury.

Therefore, do not allow flames, sparks or lighted substances to come near the battery. When charging or working near a battery, always shield your face and protect your eyes. Always provide ventilation.

WARNING: When lifting a battery, excessive pressure on the end walls could cause acid to leak out through the vent caps, resulting in personal injury, damage to the vehicle or the battery.

WARNING: Keep out of the reach of children. Batteries contain sulfuric acid. Avoid contact with skin, eyes, or clothing. Also, shield your eyes when working near the battery to protect against possible splashing of the acid solution. In case of acid contact with skin or eyes, flush immediately with water for a minimum of 15 minutes and get prompt medical attention. If acid is swallowed, call a physician immediately.

Ford Motor Company strongly recommends that lead-acid batteries be returned to an authorized recycling facility for disposal.
