Car Battery Facts and Myths

Written on September 25, 2015 at 1:01 pm

Since the invention of the lead-acid battery, the basic principle has not changed. However, over the years, car battery facts have become intertwined with myths and many people rely on information that is in fact untrue.

We explore some of the common facts and myths associated with car batteries.

Batteries naturally self discharge while in storage

Fact. Whilst in storage the battery will start to discharge and sulfation will occur when the state-of-charge is less than 100%. This relates to the discharge process when soft lead sulfate crystals are formed in the pores and on the surface of the positive and negative plates inside a lead-acid battery.
By storing the battery is a cold place, this will slow the process down.

“Maintenance free” batteries never require maintenance

Adding water to car battery

Myth. It is important to remember that during the warmer months of the year, the water in the electrolyte is lost and can also be lost due to excessive charging voltage or charging currents. For cars running permanently in hotter climates, non-sealed batteries are recommended so distilled water can be added when needed.

A good battery can last for over five years

Fact. When maintained correctly, there is no reason that a car battery should not last five years. There are a number of contributory factors that can mean that the battery life is compromised. A battery that is over- charged, under-charged or charged using a defective system can cause failure as well as when no maintenance is carried out.

Bad batteries will not harm the charging system

Myth. When a bad or weak battery is used, it can be incredibly detrimental to the vehicle and can cause premature failure due to the extra strain on the charging system or starter. When replacing a battery, alternator, voltage regulator or starter, be sure to check thoroughly for damage.

“Stop-Start” technology places greater demands on car batteries

Fact. It is well known that more and more cars come with stop-start technology. This is designed to automatically shutdown and restart the internal combustion engine. Stop-start technology is beneficial in reducing the cost of fuel and environmentally friendly by reducing emissions produced. However, these benefits come at the cost of a greater demand on the car battery. You can expect to pay more for a more sophisticated battery to work with this technology.

Old car batteries do not require a specialist recycling system Recycling symbol

Myth. Car batteries contain both lead dioxide and sulfuric acid which can be very harmful to the environment. By law you cannot dispose of with household waste; instead they should be taken to your local recycling centre, scrap metal facility or, should you be purchasing a new battery, the garage who replace it should be able to dispose of your old one for you.
