Most car batteries last around three to five years, and Texas heat can shorten that. Batteries rarely fail without warning — here's what to watch for.
Warning signs
- Slow, sluggish cranking when you start the engine
- A clicking sound when you turn the key or press start
- Dim headlights or interior lights, especially at idle
- The battery or check-engine warning light is on
- Electrical glitches — power windows or the radio acting up
- A swollen battery case or a rotten-egg smell
- White or blue corrosion on the terminals

Why heat matters
High temperatures speed up the chemical reactions inside a battery and evaporate its fluid. Many batteries are weakened over a hot summer and then finally fail on the first cool morning.
What to do if it dies
Request a jump start in the RODLX app. If the battery won't hold a charge, your CARELX technician can test and replace it on the spot — no tow required.
