Q. Why won’t my vehicle start on winter mornings?
A. Heavy-duty vehicle engines need twice as much energy to operate when the temperature falls below freezing, and if you have a weak or damaged battery that can’t produce sufficient power, it could explain why your vehicle fails to start on icy mornings.
Q. Should I use more than one battery to power my heavy-duty vehicle and its onboard accessories?
A. Having a dedicated accessory battery can help avoid no-start situations when accessories have inadvertently discharged the main battery.
Q. How do I know what battery type (conventional flooded lead acid, Absorbed Glass Mat, Lithium-ion, etc.) is the right one for my application?
A. The reason for all the different types of batteries is related to how they are being used. For example, traditional flooded batteries are best suited for starting only applications. They do not work well in an application where both starting and deep-cycle use is required. Lithium-ion batteries are generally best for use in deep-cycle applications. Thin Plate Pure Lead (TPPL) AGM batteries are very flexible and can be used in both starting and deep-cycle applications.
Q. Do I need to replace my battery if I dropped it on the concrete during installation?
A. If the battery was accidentally dropped it is possible to damage the internal connections as well as the external container, ultimately leading to needed replacement. Batteries with any kind of visible external damage should not be used.
Q. How long should my heavy-duty vehicle battery last?
A. Predicting battery life is challenging as it depends on many factors such as how often the battery is used, how the battery is maintained during period of non-use and battery temperature.
Q. Can I use an AGM charger to charge my flooded lead acid battery?
A. It is typically OK to use an AGM charger on a flooded battery, but the opposite is generally not appropriate. The best practice is to use a charge profile that matches the battery type.
Q. What is an Ah rating?
A. The Ampere Hour (Ah) rating defines the capacity of a battery. A battery rated at 100Ah at the 10-hour rate of discharge will deliver 10A for 10 hours before the terminal voltage drops to 10.5 volts for a 12-volt battery.
Q. How do I properly mount my battery?
A. Batteries should be mounted to help ensure that they are secured against vibration.
Q. What if my engine overheats in the summer? How does that impact my battery?
A. Engine heat in the summer can indirectly affect your battery. Especially if your battery is close to the engine. Extreme heat can accelerate the chemical reactions inside the battery, causing it to degrade faster than usual. Additionally, high temperatures can lead to increased water loss in the battery, which can affect its performance and lifespan.
