Why your alternator is not enough for charging your 12V car battery

When it comes to maintaining the health and longevity of your car's 12V battery, relying solely on the alternator might not be sufficient. Many drivers assume that as long as they keep their vehicle running, the alternator will take care of the battery charging needs. However, this assumption can lead to a misunderstanding of how car batteries and alternators function, potentially resulting in battery failure or reduced battery life. If you’re using a battery charger like CTEK’s CS ONE you are better prepared for the road.

How to jump start an automatic car

If you drive an automatic and find yourself with a flat battery, knowing how to jump start it is very useful knowledge.
