Follow this instruction
- Wear safety clothes
- Make sure to switch off ignition and accessories.
- Take note of battery polarity: When dismantling: Detach negative (grounded) cable from negative post first. Negative post has green plastic collar, (-) minus marking, smaller size than positive and lighter in color than positive
- (when wet/used).
- When installing: Connect positive (starter) cable to the positive post first. Positive post has red plastic collar, (+) plus marking, bigger size than the negative and darker color that negative (when wet/used).
- Attach negative cable last: The presence of sparks indicates a short circuit or that the battery was connected in reverse -- recheck.
- Replace worn, frayed cables for effective transfer of battery power. For 12v use full size cable No.4 gauge. For heavy demand or unusually long connection, a bigger size should be used.
- Make sure that the battery is securely mounted. See to it that the bracket (plastic if possible) is properly torque to reduce potential damage from vibration or dislocation, especially when using a bigger battery type. A bracket is recommended if there is none.
- Clean battery terminals. Coat external surfaces with mineral grease or petroleum jelly.
- Clean surface of battery. Use of compressor advised.
- Use proper tools. Avoid hitting terminals when installing or tightening as it may result in damaged post bushing. Damaged bushings could cause acid to leak that may corrode holddown brackets, holder and terminals.
