Long Hot Spells
Summer is also a time when car batteries may fail. Long, hot spells can lead
to corrosion, as battery fluid can evaporate faster. The best thing you can do
in this instance is ensure your car battery’s connections are free from
Cold weather conditions
When weather conditions are particularly cold, it is
important to have a fully functioning battery, as it is in these conditions that
batteries must work even harder. They have much more demand placed on them.
When the winter weather arrives, motorists typically make more use of heaters
and lights, which can reduce the performance of your car battery.
What is the most common reason for a flat battery?
Between them, the motoring organisations attend over 60,000 calls a year to motorists who have left their lights on! Not surprisingly, this is the No1 cause of flat batteries.
Another reason why a battery goes flat is the style of driving it has to cope with. If you use the car on an occasional basis, or for lots of stop/start journeys, the battery hasn’t sufficient time to get recharged and, as a result, goes flat. Please tell the technician if you fall into either category and they will be delighted to advise you.
Why do batteries suddenly fail?
Most batteries don’t suddenly fail, they just wear out! Batteries are similar to tyres. As the tread depth reduces you can see when it’s time to get a new tyre. As the electrical performance of the battery reduces you need a machine to test the health of your battery so that it can be changed before it suddenly lets you down. Ask one of our technicians to test your battery to see if it will make it through the winter. It’s a FREE check!
Why do batteries fail in winter?
A battery is a chemical reaction in a box. When we were at school, we were taught that if you want a chemical reaction to work more quickly you heat it up. Conversely, when you cool it down, the chemical reaction works more slowly.
That’s why when the weather is cold the battery is at its weakest. It just so happens that when the weather is cold the car is more difficult to start as the fuel is less combustible, and the oil is thicker, adding to the problems of a weak battery.
You can get a 'pill' to put in the battery, do they work?
They only give a very short lived improvement before the battery inevitably fails. Save your money and put it towards the price of a high quality new battery.
Are old batteries recycled?
Yes, they are recycled.
The lead is used to make new batteries, the plastic case is ground down and is used again, even the acid is used to make Gypsum salt. Just about the only part of a battery that cannot be recovered are the polyethylene separators. ATS Euromaster will ensure that old batteries are returned and are safely recycled.
Battery Type & Selection
Can I fit a bigger battery than the one recommended for my car?
You certainly can. Provided it is the same voltage, normally 12 volts, and it fits under the bonnet you can fit a bigger battery. In fact, it represents fantastic value for money as the bigger the battery the less ‘work’ it has to do, relative to its power reserve, and therefore it lasts longer.
I've got a car with a stop/start facility; do I need a special battery?
Almost certainly yes, particularly if you have regenerative braking. Our technicians can advise you on the correct battery for your car. All our batteries are equal in power to those fitted when the car was first made. Many are higher power!
Can I use my car battery in my caravan?
No, not a good idea! A car battery is designed to give a massive surge of power when you turn the key. A leisure battery gives its power slowly, for a long time.
A leisure battery can cope with the discharge/recharge regime that back up power supply requires. A car battery cannot do this without causing life shortening damage. ATS can supply you with a complete range of leisure batteries for the outward bound.
I've been told that as the car gets older you should think about getting a more powerful battery; is it true?
Yes, it is true. When the car was first made, the manufacturer decided on the correct battery by taking into account the car’s requirements. Now, years later, the car has had extra electrical consumers fitted and has begun to wear. The engine doesn’t fire so quickly, the charging system is less efficient and, almost certainly, the car is serviced less frequently than when it was brand new. In these circumstances, a bigger battery is more able to cope with the difficulties that age brings.
What do all the performance ratings mean?
There are three main ratings:
Ampere Hours is also called the capacity. This figure gives you an idea of the total amount of power stored in the battery.
Cold start performance is a rating to show how much power can be supplied to the starter motor in 30 seconds.
Reserve capacity is a measure in minutes to show how long the battery will continue to run the car, without being charged, while 25amps are being consumed. In other words, ‘how long have I got to get home?’
Why don't you need to top batteries up anymore?
Years ago, batteries were made with a lead alloy including metal called antimony. The presence of antimony, together with the high charging voltages of a dynamo made the battery lose water.
Today, the antimony has been replaced by calcium and the alternator, charging at 14.4 volts, has stopped the battery losing water. If the alternator is faulty and charges above 14.4 volts then the battery will lose water as it did in day’s gone by.
If I have to leave the car for a long time what should I do?
If you leave the car for a long time the ‘hotel’ load will drain the battery. The immobiliser, alarm, computer and clock all demand power when the engine is switched off.
First, consult the car’s manual. If it recommends the removal, or disconnection of the battery then follow the instructions given in the manual. There are products available that you can connect to the battery that charges the battery at a very low rate, enough to counteract the ‘hotel’ load on the car.
Can you store a battery off the car?
Yes, you can. The battery should be kept fully charged and stored in a cool dry place. There is an ‘old wives tail’ that you shouldn’t store a battery on a concrete floor as it drains the power- rubbish! The only risk of putting the battery on a concrete floor is that a protruding stone may puncture the plastic case and cause a leak.
What is the white deposit sometimes found on the terminals?
It is a compound created by the acid fumes, lead and the electrical current. You can remove it by pouring boiling water over the affected part. Use a petroleum jelly to protect the terminals in future.
What is the liquid in the battery?
The liquid is dilute sulphuric acid (H2SO4). Great care should be taken to ensure that you protect your eyes when working with exposed acid. If you get acid in your eyes, wash with copious quantities of water and seek immediate medical help. Should you get it on your skin, or clothes, wash immediately with water.
I've been told that batteries can explode, is it true?
When a battery is being charged, it gives off hydrogen. Hydrogen is highly volatile gas and, if ignited by a spark, or naked light, can cause the battery to explode. Avoid the risk and get ATS Euromaster to fit the battery for you, it’s FREE!
