Do You Make These Mistakes And Car Battery Keeps Dying?

car battery keeps dying

The major purpose of car battery is to store electricity for starting engine. If it is unable to store enough energy it can damage the charging system or starter motor. Car battery keeps dying if there is a fault in wiring or fault in the battery.

Battery with smaller current damages your engine. It also annex the cost of repairing to run it again. A healthy battery acts as a surge guard for all the electronic components. It supplies power for a while to use lights, stereo, and GPS when the engine is not running.

Car Battery Keeps Dying: Why?

We are going to discuss main reasons, our routinely mistakes and faults in wiring by which car battery keeps dying.

Habitual Power Drains

  • We plug in phone chargers and don’t bother to plug out, these constantly draw power from battery.
  • Stereo system remain “On” even when we don’t use it, drains power.
  • Interior / cabin lights some time we forget to switch off before leaving vehicle.
  • Sometime we don’t turn off parking lights or may forget.

Defective Charging System

  • A defective charging system while vehicle is running, can drain battery. It is due to failure of pushing out enough voltage, ideally 13.5 to 14.5 volts.
  • If relays not working properly, car battery keeps dying.

Defective Wiring: Car Battery Keeps Dying

  • Defective wiring is blood sucker for battery. Faulty fuses drains battery beyond the ways.
  • Incorrect installations or add-ons which manufacturer not recommends drains battery and can lead to ignite fire in electrical system.
  • Loose terminals may not drain battery, however they won’t allow full current to charge.

Extreme Weather

  • Reduced temperature increases internal resistance of battery cells. It allows less charging current.
  • Bitterly-cold weather can drain upto 60% of battery power. It effects chemical activity which supervsie the holding of charge.
  • Very hot weather accelerates chemical reaction which also drains battery faster.
  • Overall lifespan of battery is reduced both due to extreme cold and hot weather.

Pre-mature Aging Process

  • Excessive heat, overcharging, substantial vibrations, fast charging and many other factors of this nature reduce lifespan of a battery.
  • Poor maintenace, charging and discharging with low acid levels reduce charging capacity and lifespan of battery. Cells loss capacity of holding charge, however battery keeps dying.

Excessive Short Trips: Car Battery Keeps Dying

  • If you more often tak short trips like drive for less than 15 minutes. You switch off and then after sometime you start the car. It puts extra burdon on the battery.
  • Alternator / Generator don’t get enough time to recharge. However, next time when you start the car it drains extra power from battery. Ultimately cells loss holding power of current.

Defective Alternator

  • You are using battery power as usual but alternator is not working properly, drains battery. Next time when you try to start the car, it may not start. Because alternator is unable to produce as much current as your are using.

Short Circuit: Drains Battery

  • Faulty wiring may lead to short circuit. In this situation excessive current passes. More heat generated and chemistry of battery effected.
  • Battery liquid might be evaporate or expand. It leads to battery draining.
