Leaving the Headlights On

The most common thing that quickly drains the battery of your Acura is leaving the headlights on. This could be overnight or even while you are at work during the day.

If this is the case, then you don’t have to worry about this becoming a problem, although checking the lights before you walk away from your vehicle is still a good habit to have.

“Parasitic Draw” or Failing to Charge

Another reason why your Acura could have a battery drain problem is a “parasitic draw.” When your vehicle is off, the battery continues to provide power to smaller items including the alarm system, clock, and radio.

The battery can drain while supplying a seemingly unnecessary amount of electrical power to these features.

Old Battery

One last reason why you may experience battery drain problems in your Acura is that the battery is old. As the battery ages, it becomes less efficient and is prone to failure. You will know that it is time for a new battery when your Acura dies right after you just jumped it.
