Charge Your Car Day
Stay Ready. Power Every Moment.
Charge Your Car Day is CTEK's global awareness campaign dedicated to helping motorists understand the importance of battery care.
Held every year on 5 October, the campaign encourages drivers to take a few simple steps to help reduce the risk of unexpected battery failure through regular smart charging, simple battery maintenance and carrying a portable battery booster.
Because when your battery is ready, you're ready.
Why It Matters
Modern vehicles place greater demands on the 12V battery than ever before. Navigation, infotainment, lighting, safety systems, keyless entry and automatic start-stop technology all rely on it, while shorter, more frequent journeys may not always provide enough time to fully recharge the battery.
The result? Battery-related issues remain one of the leading causes of roadside assistance worldwide.
150 Things Could Be Draining Your Battery
Modern vehicles can containup to 150 electrical consumers relying on the 12V battery.
The Stay Ready Snapshot
Modern vehicles are changing. Battery care needs to change too.
150 Electrical consumers can rely on a modern vehicle's 12V battery.
45.4% Of ADAC roadside assistance call-outs in Germany during 2025 were caused by the starter battery.
7 million Approximate battery-related roadside assistance calls attended by AAA across the United States during 2024.
72% Of motorists surveyed by CTEK rarely or never check their battery.
1 in 5 Surveyed motorists don't know how to charge their battery.
The message is clear
Vehicles are becoming increasingly sophisticated, but many drivers still underestimate one of the hardest-working components in their vehicle.
Looking after your battery isn't just about avoiding breakdowns—it's about staying ready for whatever life has planned.
Why Today's Batteries Work Harder
The role of the 12V battery has changed dramatically.
Today's vehicles rely on it to power and support far more than simply starting the engine. It provides energy for navigation, infotainment, lighting, driver assistance systems, climate control, security features and automatic start-stop technology.
Hybrid and plug-in hybrid vehicles also depend on a 12V battery to operate many essential low-voltage systems.
At the same time, driving habits are changing. Frequent short journeys and vehicles that spend long periods parked may not always allow enough time for the battery to fully recharge.
Over time, this can reduce battery performance and increase the risk of unexpected failure.
Charge. Boost. Stay Ready.
Battery readiness comes down to two simple steps.
Charge
Regular smart charging helps keep your battery in optimum condition, reducing the risk of unexpected battery failure and helping to extend battery service life.
Whether you drive every day or only occasionally, maintaining a healthy battery helps ensure your vehicle is always ready when you need it.
Boost
Even a healthy battery can fail unexpectedly.
Keeping a portable battery booster in your vehicle gives you the confidence to restart your battery without relying on another vehicle or waiting for roadside assistance.
Together, a smart charger and a battery booster help you Stay Ready for every journey.
