Car batteries can sit unused for varying lengths of time. Understanding this can help prevent unexpected breakdowns and costly replacements.
Car batteries lose charge over time, even when not in use. Factors like temperature, age, and type of battery influence how long they last. Hot climates speed up battery discharge, while cooler temperatures slow it down. Older batteries lose charge faster than new ones.
Lead-acid batteries, common in most cars, typically last about two to four weeks without use. For optimal performance, check and charge your battery regularly. This simple maintenance can save you from being stranded with a dead battery. Always keep a charger handy and inspect the battery for any signs of corrosion or damage. Small steps can make a big difference in battery life.
