And how we can help you to restore the vehicle’s electrical system efficiency!
When you put the key in the ignition to start your vehicle, everything that happens after that depends on the battery tucked away in your vehicle’s engine compartment. When it is cold outside, the engine is more difficult to start, so the battery needs to work harder.
Today mainly valve-regulated batteries such as AGM and Gel are supplied. These chemistries have the same challenge, if not greater, with sulphation, as the ions migrate in gel, and there are of the greatest importance that each individual cell is free of all sulphation.
Valve regulated batteries don’t have liquid electrolyte. The acid is instead either bound in gel or absorbed in a glass mat (AGM). Both battery types are spill-proof, and no acid leakage occurs even if the battery is damaged or the casing cracks.
In valve-regulated batteries, the gas produced during charging is converted into water inside the battery. Therefore, only insignificant amounts of gas are released during normal handling. All recombination batteries have a safety valve that opens if the pressure inside the battery becomes too high, e.g., in connection with overcharging. VR batteries are sealed and can’t be opened. They therefore cannot be topped up with water either.
Gel batteries are valve-regulated batteries where a silicon solution is added to the electrolyte which causes it to solidify into a jelly.
The robust technology behind the gel batteries provides good cycling properties and a higher internal resistance. This gives a lower starting power than for AGM batteries and freely ventilated batteries.
AGM means “absorbent glass mat” and is a group of valve-regulated batteries with a special glass mat separator. All the electrolyte is absorbed in separators and plates and because the construction has low internal resistance, the battery has very high starting power.
AGM batteries withstand cycling (i.e., repeated discharges and recharges) significantly better than freely ventilated batteries. The properties of AGM batteries mean that they are also suitable for micro-hybrid cars.
There are lead plates submerged in electrolyte liquid inside a standard lead acid battery. This combination catalyzes an electrochemical process that ultimately supplies a voltage boost to the battery’s terminals. This chemical activity is hastened by heat, but internal corrosion with the cells also increases in pace, shortening your battery’s useful life.
This is especially true with batteries that routinely attain high internal temperatures since the capacity cannot be recovered once it has been destroyed by heat. On the other hand, chemical processes are slowed by cold temperatures in the same way they are sped up by heat. This is why you may see your battery slowing down in colder climates such as Nordic countries, even though the actual charge level of the battery may be the same.
When the temperature is lower, the capacity of the battery to provide adequate power to start and maintain the operation of the vehicle is reduced. Meanwhile, the CCA scale is used to grade batteries for automobiles, known as Cold-Cranking Amperage.
This refers to the maximum amount of current that a battery can produce for a period of thirty seconds at a temperature of -18 degrees Celsius before the voltage drops below a certain threshold. Remember that the bigger the number of CCAs a battery has, the better it will operate when it is exposed to cold temperatures.
In cold weather, your battery has to work harder. However, your alternator may only be able to fully charge it to around sixty percent of its capacity. Essentially, around fifty percent more alternator issues occur in the winter and during really cold temperatures. The most terrible thing is that this may be costing you an extra 5-10 HP and a significant amount of fuel.
If you’re going to be traveling in severely cold weather, it’s crucial that your battery is always completely charged and maintained by a high-quality charger. On the other hand, a fully charged lead-acid battery may operate at temperatures as low as -50 degrees Celsius, but a battery with a low level of charge can freeze at a temperature of only -1 degrees Celsius. The cells of a battery might be permanently damaged when the water inside of it freezes and expands.
Now that you know how batteries are impacted by cold weather, you can work toward finding a solution that will allow them to survive the long, harsh winters in Scandinavia.
Along these lines, our Canadus Battery Reconditioner/Refresher prevents sulfation crystals from accumulating on the battery plates, restoring the electrical system to like-new performance and extending the life of the lead acid batteries. You may not have known, but this reduces the car’s ecological footprint as well. In particular, batteries that last longer and perform better may increase fuel economy, lessen the amount of lead used, and cut down on carbon emissions.
