If your battery is getting old, then it’s undoubtedly going to start causing problems for you sooner or later. For a battery that has been manufactured more than 4 years ago, it’s going to start experiencing some issues which means it’s time to start looking for a new one before the old one completely dies.

Manufacturing Defect

As frustrating as it may sound, sometimes car batteries can die for no reason. It can be due to something like a factory defect, which means that even jumper cables or a portable battery charger won’t do anything.

Corrosion will occur when moisture has built up on the battery and its terminals, which is a pretty clear indicator that the battery is only getting worse with time. If you notice corrosion, you can try scrubbing it off with a brush and battery cleaning solution, but this may only be a short-term solution.


You may notice that in extremely cold temperatures, your car has a harder time starting. Constant exposure to low temperatures can mean bad news for your battery, so if it still has a slower time starting up when it warms up outside, consider shopping for a new car battery.

Sometimes the battery isn’t the problem, and it can be something else like the alternator giving you troubles. Either way, if you think it’s time to get a new car battery or get some maintenance services done, be sure to get in touch with the team here at McDaniels Porsche!
