Car battery failure is one of the most common causes of an engine refusing to start and Rob Marshall advises that extra checks are necessary to reduce the chance of an annoying wintry inconvenience. It can be illogical for an otherwise reliable vehicle to fail to start at the first sign of a cold snap.
Although requesting a garage to supply and fit a car battery for you is the most convenient option, many people prefer to buy the part from either an online or high-street retailer.
The first thing to check is whether or not the battery will fit physically into your car and you should measure the length, width and the height in millimetres.
Although battery lifespan depends on how it is used, most types last for between three and five years. Even if you are not adept at DIY, many garages offer a free test, which will identify whether or not the car battery is able to cope with the rigours of winter use. Some car batteries are not sealed, which means the caps can be take off and the level of electrolyte can be maintained, by adding distilled water, until the level is just above the internal plates. Even if DIY is your forte, most modern car batteries are sealed, meaning very little can be done to them, apart from ensuring that the terminals are clean.
Unfortunately, car batteries can freeze and the rate at which they do so increases depending on how discharged they are. If a battery is left discharged for a long period, a chemical reaction occurs internally that can cause permanent damage, a process known as sulphation.
On more recent models, even disconnecting the car battery can cause problems with the electrical system. Batteries have a finite life and, although there are retail products available to rejuvenate a tired item, at best, they only tend to delay the inevitable new purchase.
About GEM Motoring AssistGEM Motoring Assist are a breakdown cover company and road safety charity that has been serving motorists for over 80 years.
GEM Motoring Assist's free mobile app has been developed to give our members extra peace of mind.


GEM Motoring Assist is a trading name of The Guild of Experienced Motorists which is authorised and regulated by the Financial Conduct Authority (FCA). Please have your installer double check what will fit your vehicle before you order parts from us. This circuit determines the cold cranking amps of a battery by firest discharging the surface charge, then checking the internal resistance. The truth is that lower temperatures place its mechanical components under extra stress but a few simple checks will reduce the chance of your car battery letting you down.
A Cold Cranking Amps (CCA) figure is given, indicating how capable the battery is at starting a cold engine. As batteries cost more than the labour involved to fit them, paying a little extra for an extended guarantee, some of which can be up to five years long, can be a prudent move, especially if you cover a low annual mileage. Green-coloured corrosion, which can affect the electrical connections between the battery and the vehicle’s terminals, can be dissolved by boiling water.
If your engine does not start first time, operate the starter in ten second bursts and then turn the ignition off for 30 seconds, before trying again. Heated rear windscreens tend to work in conjunction with heated mirrors and consume a lot of electrical energy.
If a battery has a very low rate of charge, the electrolyte’s PH value increases closer to that of water and becomes more vulnerable to freezing. This might be caused if your car is out of use for a long time, which is not helped by some electrical accessories, such as a clock or alarm system that drain the battery while it is parked. Therefore, you should read the instruction manual, or consult a technician, to see if there is a procedure, which will allow the vehicle’s computers to ‘power down’. This has been developed for you, the member, to ensure that if you break down you can tell us exactly where you are.
This gives a more realistic measurement than simply measuring the instantaneous drop in voltage with a load.


Then, confirm that the position, size and shape of the terminals are the same as your replacement.
If your motoring consists mainly of short journeys, it may be advantageous to buy a battery with a higher CCA than that which was fitted originally.
Coating the terminals with Petroleum Jelly (such as Vaseline) will help to discourage corrosion from building in the future. Lights also consume a lot of power but never turn anything off, if it will prejudice road safety. Like water, if the electrolyte freezes, it expands, buckling the internal lead plates and rendering the battery useless.
In this case it would be better to disconnect and remove the battery from the car and charge it slowly, using any one of the many car battery chargers on the market, which will replenish the car battery slowly. Additionally, the Ampere-hour (Ah) rating ascertains the number of amps that the battery can provide over a 20 hours period. If you only tend to cover short journeys, it is prudent to take your car for a longer run, of at least 20 miles, which will help recharge the battery to an acceptable level. However, be aware that batteries give off highly explosive gases, when being recharged, and necessary safety precautions should be taken. Even a modern car will deliver more power to the battery above idling speeds but never be tempted to leave your car unattended, on a driveway, with the engine running.

    Everything you've out on the company's batteries will contain an amount of recycled battery material.

    Amp-hours used would be 20 (amps) x05.
