Don’t let a dead battery spoil your summer getaway
17 July 2025
Summer means longer days, sunshine and road trips. Whether you're heading to the coast, the countryside or just enjoying a staycation, your car battery should be the last thing you’re worrying about. But every year, thousands of summer holidays are disrupted by one common issue: a dead car battery.
According to roadside assistance services across Europe and the US, battery-related breakdowns are among the top reasons for callouts during summer months. High temperatures, combined with infrequent use, short journeys and added load from air conditioning and in-car tech, put serious strain on your vehicle’s battery.
Many drivers mistakenly believe that cold weather is a battery's worst enemy. While winter can be tough on an already weak battery, heat is just as dangerous – if not more so. Elevated temperatures accelerate chemical activity inside the battery, increasing the risk of fluid evaporation and internal damage. This can significantly shorten battery life or even lead to sudden failure.
Avoid summer stranding: charge smart
That’s where preparation makes all the difference. Just as you check your tyres and fluids before a long journey, your battery deserves the same attention. A healthy battery is a charged battery – and the best way to ensure it stays that way is by using a smart charger such as the CTEK MXS 5.0.
The MXS 5.0 isn’t just any charger. It features temperature compensation, a critical function in summer. This intelligent feature automatically adjusts the charging voltage based on ambient temperature, preventing overcharging in the heat and ensuring your battery is optimally maintained.
It’s also fully automatic – just connect it, select the mode and let it do the rest. The MXS 5.0 goes through a patented eight-step charging process that includes de-sulphation (and, if selected, reconditioning for certain types of batteries), helping to restore lost battery performance and extend its life.
Top tips for summer battery health
- Charge before you go – don’t leave battery maintenance until you’re packing the car. Charge your battery the night before to start your journey with full power.
- Avoid short trips – these don’t give the alternator enough time to recharge the battery. If you're not driving far, top up the charge manually.
- Keep it cool – park in the shade or garage when possible. Excessive heat under the bonnet can quickly degrade battery health.
- Maintain if storing – leaving your vehicle unused for weeks? Connect a maintenance charger such the MXS 5.0 to prevent discharge.
Enjoy the journey, not the tow truck
A little battery care goes a long way toward a smooth and stress-free vacation. With the CTEK MXS 5.0, you get peace of mind knowing your car is ready when you are – no unexpected surprises, no roadside delays.
Make battery maintenance part of your summer routine, and you’ll be free to enjoy every mile. Happy holidays from all of us at CTEK.
