Car batteries are designed to power headlights, dome lights, and various other accessories whenever the engine is off, but they have a very limited capacity to do so.

The most common reasons lead a car battery to die repeatedly including loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the alternator can provide, and even extreme weather.

• Headlight or even a very dark dome light, will run out of battery at night.

• When you are outside in the dark, be sure to check for any interior light.

• Some headlights are designed to keep a period of time, but the faulty system may keep them permanently.

2.Battery in weak or poor condition.

• A poorly maintained or weak battery may not hold a charge very well.

• Even small drainpipes, such as the memory function of a car radio, can kill a very low power battery

3.Corroded or loose battery connections.

• when are you driving , the corrosion of battery connection may stop charging system will be shut down.

• Loose battery connections can also cause problems.

4.Other parasitic drains in the electrical system.

• Common drainage system including the glove box and a suitcase light, when they should not, these will light up or keep still.

5.Extremely hot or cold temperatures.

• High or low temperatures it will kill the new battery or good battery, but weak batteries or old batteries may  fail in extreme conditions.

• Extremely hot or cold weather can also magnify potential issues.
