5 Signs Your Battery Needs Replacement
January 8, 2026
The battery is the electrical heart of your vehicle. In Colombia's tropical climate, batteries tend to degrade faster due to the heat.
Sign 1 — Slow or difficult start
When you turn the key and the engine takes longer than usual to start, or you hear a clicking sound without the engine turning over, the battery may be depleted.
Sign 2 — Dim or flickering lights
Dashboard lights or headlights that appear dimmer than usual indicate the battery is not delivering enough voltage.
Sign 3 — Rotten egg smell
A strong sulfur smell near the hood indicates the battery is releasing hydrogen sulfide gas. Take the vehicle to a technician immediately.
Sign 4 — Swollen or deformed casing
If the sides of the battery are bulging, it was exposed to excessive heat or overcharging. A swollen battery must be replaced immediately.
Sign 5 — Battery warning light on the dashboard
The battery icon on the dashboard can indicate problems with the battery or the alternator. Never ignore this light.
