Visual Check

WARNING: Prior to handling or servicing batteries, read, understand and observe the Warning and Safety Measures for lead-acid batteries.

Prior to performing any measurements or tests, perform a visual check of the battery and battery terminals. Check for:
- Secure mounting of battery; must not be able to move battery in mounting by hand.
- Cracked battery case and resulting corrosion damage to surrounding area.
- Loose, damaged or corroded battery posts and terminals. If terminals are loose, observe battery terminal tightening torques.

WARNING:
- An improperly secured battery can lead to damage.
- Excessive vibration due to an improperly secured battery will reduce the battery service life, and the battery hold-down bracket could damage the battery housing and lead to electrolyte leakage.
- Ensure that all battery post/terminal connections are securely installed and tightened according to the torque value specified.
- Intermittent contact at battery terminals may spark or cause electrical system malfunctions.
