If your car sits unused for as little as two weeks, the battery can run out. Today's cars are packed with advanced technology, but there's a downside. The constant monitoring of car systems by gadgets and computer technology in modern vehicles means that even when parked, the newest models are always on.

There are various reasons for this common question, including factors like age, corrosion, issues with the alternator, extreme weather conditions, or the classic mistake of leaving headlights on.

Extreme temperatures, both hot and cold, can adversely affect your battery, especially if it's already in a weakened state. Many customers in warmer, southern climates like New Braunfels may not be aware that high temperatures can drain their batteries. Conversely, cold temperatures slow down chemical reactions, causing your car battery to seem sluggish and appear weaker than it actually is. While most modern batteries are engineered to provide ample power even in cold conditions, older batteries or those nearing the end of their lifespan may struggle to start your car on exceptionally chilly mornings.
