How Does A Battery Work?

Ford cars incorporate many sophisticated technologies, therefore they require equally advanced batteries to power them.

Most vehicles use a lead acid battery to power the electrical system of the vehicle. Inside this type of battery are lead plates surrounded by an electrolyte liquid. This combination creates a chemical reaction resulting in a charge at the battery terminals. A battery's ability to generate electricity through the electro-chemical reaction will diminish as the chemicals within the electrolyte are used up. Temperature plays a significant role in how long your battery lasts. 

High temperatures surrounding the battery will speed up the chemical reactions making it easier for the battery to produce electricity, but it also increases the internal corrosion that occurs within the cells thereby reducing the expected life of the battery. Similarly, cold weather slows down the chemical reactions making it harder for the battery to produce electricity, and therefore harder to start your vehicle in very cold conditions. 

Automotive batteries are rated in CCA (Cold-Cranking Amps). This is the amount of current a battery can deliver for 30 seconds at -18 C without dropping to a specified cut-off voltage. A fully charged lead-acid battery can survive up to –50 C, but a battery with a low state of charge can freeze at –1 C. When the de-ionized water in a battery freezes, it expands and can cause irreparable damage to the cells. 

The Power Behind Your Vehicle’s Technologies

Ford vehicles incorporate many sophisticated technologies and therefore require equally advanced batteries to power them. The best advice for what battery to use specific to your vehicle can be obtained from your local Dealership. Using the wrong battery, or having it poorly installed can cause problems for difficulty starting your vehicle to causing the battery to explode and an under-bonnet fire. Always refer to your Ford Dealership when servicing or changing your battery.
