A car that sits for days or weeks usually won't start because the battery slowly drains. A jump start often fixes it, then drive for a while to recharge. For long absences, use a battery maintainer or have someone start the car periodically.
Coming back from a trip or a few weeks without driving and finding a car that won’t start is very common.
Why does this happen?
Modern cars use a little power even when they’re off: the alarm, the computer and the key fob receiver all draw small amounts. Over days or weeks, that drains the battery, especially if it is already old or the weather is hot.
What can I do?
- Try a jump start. If the car starts, drive it for a while so the alternator can recharge the battery.
- Check the battery’s age. If it is several years old, it may not hold a charge anymore.
- Look at the tires. Tires lose air while sitting. Check the pressure before driving.
What if it still won’t start after a jump?
The battery may be too weak to recover, or there may be another problem (starter, fuel). A tow to a mechanic is the next step.
How do I prevent it next time?
- Use a battery maintainer (trickle charger) if the car will sit for weeks.
- Ask someone to start and drive the car every week or so.
- Before a long trip, have the battery tested if it is getting old.
