Car Battery Myths And Facts Dispelled: Part 1

Automotive batteries are the least understood of a vehicle’s accessories, which is surprising, given that it is critical to how well a car can operate its starting and auxiliary capabilities.

To help out car owners and dispel the false beliefs regarding batteries, here are some of the most common car battery myths and facts:

Myth A: Once fully charged, batteries can be stored indefinitely

The facts – A battery naturally self-discharges at a rate of 1-60% every month. The rate depends mainly on the type of car battery and the temperature in its environment.

If the temperature in the storage area is high, the battery will self-discharge faster. It also does not matter if the battery is sitting on a concrete floor. An old myth that is still doing the rounds says that batteries will discharge faster when stored on concrete.

The myth is based on car batteries used in the 1900’s, which were contained in wood boxes lined with tar. This material is porous and the external leakage of batteries simply made them discharge faster, making car owners think that the concrete floor was the culprit. Today’s batteries, however, are covered by cases made from hard rubber or polypropylene, which helps protect them from any potential external leakages.

Myth B: Operating the car, will help recharge the battery to its full capacity

The facts – It all depends on specific factors, such as the temperature, the amount of power that the battery has remaining and how much voltage charge is sent by the alternator to the battery. Making short trips or running the engine on idle will not charge the battery fully.

It is also a mistake to entirely rely on “warming up” the automotive battery by increasing your consumption of power such as by turning on the headlights. In the majority of cases, this will be a futile attempt to start the engine. If the battery needs to recharging, it’s best to use a quality car battery charger.

Myth C: Sealed maintenance free batteries, don’t require maintenance

The facts – In fact, they do. Car batteries that are categorised and sold as maintenance-free are not as self-sufficient as they seem. Maintenance free batteries are sealed, so electrolyte levels are maintained by the Century Advanced Labyrinth Chamber, that works with the Double Lid Technology, to transform vapours into condensed water and redirected back into the battery.

However, it is not true that they will never need maintenance. Regular maintenance such as checking loose terminals, connections and signs of over-charging by your auto electrical system is necessary. The fact is, the hotter an environment and under-bonnet temperatures are the more electrolyte fluid a battery will lose.

The Century Ultra High Performance 36 Month Warranty and Century High Performance 24 Month Warranty sealed maintenance free batteries, are engineered with internal components and materials to combat excessive water evaporation in hot conditions.


To retain your battery in optimum health, it’s crucial you define the correct car battery myths and facts. It will help you set-up and observe a regular maintenance routine.
