How your car battery works?

As NASA puts it, a battery “translates chemical energy into electrical energy.” Your car’s engine won’t start without the battery, and the electronics won’t work.

Battery died in cold weather

Car batteries can die any time of year, but they mostly tend to kick the bucket during winter. This is due to the way electric charges are created in a car battery: Liquid electrolytes mix with lead plates inside the battery, producing a reaction that creates an electric charge.

When the battery is warm, the rate of that reaction is increased. This means less power is required to deliver voltage to the starter (which starts the car) and keep that voltage stabilized (so the engine continues to run). When the battery is cold, the opposite happens.

The reaction rate is slowed, which means a higher charge is required to start and run the vehicle. At 0℃, a typical Car Battery loses about 35% of its strength. At -17℃, it loses about 60%. Over a battery’s lifespan, as it naturally deteriorates from internal corrosion, it becomes more difficult for the battery to deliver that higher charge during cold snaps. When this happens, the battery is more likely to die.
