Car Won’t Start in Winter? The Solution Is Here

Ensure your car starts reliably in winter with a 12V Sodium-ion battery. Discover cold weather car batteries with self-heating technology for stronger, worry-free winter starts.

Why Car Batteries Fail In Winter?

After a car battery fails, many drivers suddenly find their cars struggling—or failing—to start. In fact, thick oil and stiff components make your engine motor draw more power, just when your engine needs it most. A winter car battery is engineered to deliver reliable starting power, ensuring your vehicle gets a strong, consistent jump every time.

What to Look for in a Winter Car Battery?

After seeing how cold weather can challenge your engine, the next question is: why do some batteries start a car easily while others struggle—even when they look the same? The key isn’t a battery’s appearance, but whether it’s built to stay active in the cold, giving your engine the power it needs to start every time. A good winter starting battery allows drivers to start their cars reliably without jumper cables or outside assistance. Many of these batteries include self-heating technology to maintain optimal performance in extreme cold.

A Winter Starting Battery Built for Cold Starts

Car Won’t Start in Winter? We have the solution. The Sodium-ion (Na⁺) battery is the next-generation upgrade over traditional LiFePO4 batteries, specially designed to handle extreme temperatures from -40°C to 80°C. It provides dependable starting power in extreme cold, helping your car start instantly without hesitation.

The Sodium-ion (Na⁺) starting battery CB08N, paired with the Carku Battery App, is ideal for winter conditions. The app makes it easy to monitor your battery’ health and activate the self-heating function whenever needed. You can also update your battery settings through the app based on your driving and climate conditions, ensuring reliable starts even in extreme cold.

Note for Siberia: In extremely cold regions, drivers often rely on engine heaters or battery warmers. Without them, gasoline may not vaporize properly, making the engine harder to start and requiring extra effort.

Especially for daily passenger car use, the 12V sodium-ion battery with 1000A cranking power and self-heating function significantly improves cold starts, achieving up to 85%~95%% more reliable starts in freezing conditions.

Frequently Asked Questions

1.What is the benefit of sodium-ion batteries? 
Sodium-ion batteries take advantage of their inherent low-temperature performance, retaining up to 90% of their discharge capacity at -20℃.

2.How to Test if Your Battery Is in Good Condition?
Use a multi-meter to measure the battery voltage. A fully charged 12V battery should read around 12.6–12.8V when the engine is off. If available, car Na+ battery paired with the Carku Battery App, allow you to check battery health, self-heating status, and other key parameters in real time.
