CTEK Asks Your Battery Survived Winter. Will It Survive Summer?

CTEK experts urge drivers to prepare before their first ride or drive

CHICAGO, May 19, 2026 /PRNewswire/ -- 2026 brought one of the warmest starts to spring in over 100 years. As thousands of drivers bring cars, motorcycles, and boats out of winter storage, industry experts warn that summer is one of the most common times for battery-related breakdowns.

After months of cold weather, short journeys or complete inactivity, many vehicle batteries are left partially discharged — even if the vehicle appears fine.

For enthusiasts especially, that first summer start isn't just functional, it's emotional. It's the reunion after months apart. And nothing dampens that moment faster than a dead battery.

Battery specialists at CTEK are encouraging drivers to take simple preventative steps before turning the key.

Head of North American Operations at CTEK, Steve Hayes explains: "A weak battery rarely gives a dramatic warning. It quietly loses performance over time, particularly during winter storage. A quick check and recharge before your first drive can save frustration, call-outs and unnecessary replacements."

Why Summer Is a Risk Period

• Batteries naturally discharge when a vehicle is unused
• Cold temperatures reduce battery efficiency
• Modern vehicles continue to draw small amounts of power even when parked
• Short winter journeys often don't allow full recharge
• By spring, many batteries are operating below optimal charge levels, even if they're only a few years old.

Summer Readiness: 6 Expert Tips Before Your First Drive

1. Check battery condition before starting
   Use an intelligent charger with built-in diagnostics, such as the CTEK CS ONE Gen 2, which automatically analyzes battery health before charging.
2. Recharge before heading out
   Compact chargers like the CTEK NXT 5 are ideal for cars and motorcycles, restoring charge safely and efficiently after winter storage.
3. Use higher power for larger batteries
   Performance cars and boats with larger battery capacity benefit from a more powerful charger such as the CTEK NXT 15, designed for faster, controlled charging
4. Maintain charge during storage
   Long-term maintenance charging prevents sulphation and extends battery life. Smart chargers automatically switch to maintenance mode once fully charged.
5. Inspect terminals and connections
   While charging, check for corrosion and ensure clean, secure connections for optimal performance.
6. Keep emergency starting power on hand
   An all-in-one solution like the CTEK CS Free can provide peace of mind. The CS Free can safely charge a battery within 15 minutes, getting drivers back on the road and adventures.

From classic cars and performance vehicles to motorcycles and boats, summer marks the return of passion projects across the country. Ensuring reliable starting power helps protect both the vehicle and the experience.

Hayes continued "At CTEK, our philosophy is simple: Power Every Moment. From the first start of summer to every spontaneous ride, reliable battery care means confidence is never left to chance."
