We’ve all been there. It’s 6 a.m., cold and dark as you slip and slide your way to the truck. You grab your scraper from under the seat to de-ice the windows and turn the ignition.
Except it doesn’t turn and all you hear is the dreaded click-click. The battery is dead.
Curious why it always happens on the coldest day of the year when all you want to do is crank the heat and thaw out?
Get your day off to a better start with our preventative maintenance tips for better battery performance and products from Penray.
Why Do Batteries Die When It’s Cold?
Impact of Temperature on Battery Performance
Automotive giant Firestone says battery failure often occurs during freezing temperatures. “At 32°F, a car’s battery loses about 35% of its strength. At 0°F, it loses up to 60% of its strength, but your engine requires nearly twice that to start.”
Chemical reactions occur when a connection is created between positive and negative terminals. This reaction produces an electric current. NASA says a battery essentially turns “chemical energy into electrical energy.”
All year long, your battery is battling the elements. Cold temperatures increase your battery’s rate of discharge and result in reduced battery efficiency. But high temperatures also affect battery performance as it heads into the winter months.
All summer long, your fleet batteries have been stressed to the max. The constant warm temperatures have slowly evaporated the critical water balance of the batteries’ electrolyte (acid) levels, increasing sulfation (a buildup of lead sulfate crystals). These sulfate materials crystallize on battery plates, damaging the batteries.
Come winter, when temperatures plummet, the chemical reaction your batteries need to perform occurs more slowly and produce less of a current than they would at a higher temperature. Any damage it has incurred during the summer further impedes power production.
Even with a fully charged battery, vehicle engines are hard to start in the winter. This is because oils, antifreeze, power steering and transmission fluids have a higher viscosity (thickness, so to speak) in winter requiring even more power to start.
The damaged battery struggles to keep up. The demand is too much to start the equipment but it continues to draw on the current, shortening the battery life until it dies altogether.
It’s not just extreme temperatures that can lead to battery failure. Have you ever had a battery fail after a long break? This is because batteries continue to discharge even during periods of unuse, such as company holidays, vacations or when vehicles are off the road for maintenance.

Winter Battery Maintenance Tips for Truck Fleets
It’s one thing when a personal vehicle battery goes dead. It’s another when you have a no-start on a fleet truck or heavy equipment. Work doesn’t stop and you need to rely on your fleet to get the job done.
This is where preventative maintenance is critical to performance.
Equip your fleets with the tools you need to troubleshoot, diagnose and treat battery issues and address electrical malfunctions. We recommend managing your fleet’s battery lifecycles by having these tools on hand:
- Heavy-duty jump starter
- Battery tester with a battery load capacity of 2,000 CCA (Pass/Fail and Predictive Measures)
These tools enable you to quickly react and respond to battery failure and decrease the potential for downtime. Other ways to avoid a dead battery is to:
- Purchase batteries designed for colder temperatures.
- Fully charge your battery.
- Keep batteries in good shape by checking electrolyte levels and clearing corrosion from terminals.
- Store the vehicle or equipment in a garage or away from wind and moisture.
- Use a battery blanket.
- Replace the batteries as it nears the end of service life.

7 Signs that Your Fleet Vehicle Battery is Failing
Along with regularly scheduled preventative maintenance, you can learn to spot failing batteries before they become a problem. Pay attention when:
- Engine cranks slow
- White or blue corrosion appears on the battery case or positive post
- The battery is older than three years
- Headlights, dome lights or electronics are dim or fail
- You hear changes in the horn’s sound
- The battery case is damaged
- You smell rotten eggs or sulfur coming when the vehicle is running
