Signs you need to change your battery
- Your engine is turning over slowly
- Electrical issues such as dimming headlights, malfunctioning power windows
- Your vehicle needs to be jump started regularly
- It's old, car batteries typically last 3 to 5 years
- The battery has been left to drain below a safe voltage
For a 12-volt vehicle battery, the lowest safe voltage is generally around 10.5 volts. Below this level, the battery is considered deeply discharged and could suffer damage or reduced lifespan.
Detailed breakdown of voltage levels for a 12-volt battery:
- 12.6 volts or higher: Fully charged.
- 12.4 volts: 75% charged.
- 12.2 volts: 50% charged.
- 12.0 volts: 25% charged.
- 10.5 volts: Discharged (lowest safe level).
- Below 10.5 volts: Deeply discharged and likely damaged.
It's best to avoid letting your battery drop below 12.0 volts to maintain its health and longevity.
