Commercial fleet readiness: Preparing engine start batteries for cold mornings

As colder mornings set in, ensuring your commercial fleet is ready to perform becomes even more important. Engine-start batteries work harder during winter, as low temperatures slow chemical reactions, reduce available capacity and increase the power needed to start engines. Without proper preparation, the risk of slow starts — or no starts at all — rises significantly.
The winter impact on battery performance
Cold weather affects both the efficiency and reliability of automotive batteries. Engines require more cranking power, and vehicles left idle overnight are more likely to experience voltage drops. Over time, this strain can shorten battery life and lead to unexpected downtime — something no fleet can afford during busy winter operations.
Steps to keep your fleet ready
Taking proactive steps now can make all the difference when temperatures fall.
Check cold-cranking amps (CCA): Choose batteries with sufficient CCA ratings to deliver high current in freezing conditions.
Maintain a full charge: Batteries kept fully charged are less likely to freeze or lose capacity.
Inspect regularly: Visual checks for corrosion, secure connections and signs of wear help identify weak batteries before they fail.
Plan maintenance schedules: Regular testing and timely replacements ensure consistent performance across your fleet.
Powering performance in all conditions
