Avoid letting batteries go unused as they will self-discharge over time and if allowed to remain discharged, could suffer permanent failure. How quickly discharge occurs depends on the type of battery and the temperature it has been stored at.

1- Human Error

2- Loose battery connections

3- Temperature

A number of factors account for quick battery discharge-

• warm weather shortens battery span as the fluid in car batteries evaporates faster
• Likewise, cold weather slows down car battery (e.g, in 32°F, 35% of the car strength is lost, while 0°F consumes 60% of car battery strength)
• short rides prevent the battery from charging
• excessive usage of Air Conditioner or radio eats up battery power
• loose cables, corrosion, defective alternator or a worn-out battery can drain off car energy
• common human errors such as forgetting to turn off car headlights, leaving the internal lights on etc. can significantly drain off your car battery power.

1. Check the electrolyte level
2. Test battery State of Charge (SOC)
3. Recycle the battery
4. Keep battery at the correct charge when not in use
5. Keep clamps and cables clean
6.
