Fastfix car battery replacement Frequently asked questions

Every make and model of a car has its own battery requirement. The requirement is based on physical dimension of the car battery tray as well as the AH (or Reserve Capacity) and CCA required. You can find out exact requirements of your car either by inspecting the existing car battery or in the owner’s manual.  As car battery specialists, FastFix will be able to advise the exact battery requirements if you tell us the make/model (and year) of your car.

The AH of a car battery is a unit of measure which states how long the battery can power a certain load and still retain a usable charge for car starting. The higher the number, the better, and more expensive the battery.  However, this does not mean that you should use the highest AH battery available. This is because every car is engineered to support car batteries of a certain AH. If you attempt to go above or beyond the AH recommended, you may harm your car’s electrical system by either shorting the electrical system or putting a strain on the electrical equipment

Cold Cranking Amps is the amount of power, in Amps, that the car’s battery is able to supply in order to start the car’s engine. The technical definition of CCA is the maximum amount of Amps that a battery is capable of delivering at an ambient temperature of zero degree Fahrenheit for 30 seconds before the battery is no longer able to supply a usable amount of power. When you start your car, the battery has to supply enough power to the starter to run the motor over with enough speed to start. It must also supply enough power to the ignition system to provide a hot enough spark to make the engine start. Additionally, with newer cars, you will have fuel pumps, injector systems, computers and dash instruments which will all pull power while starting. If your battery is not capable of supplying a large enough current punch when starting, it won’t start the car. Car batteries are designed to supply anywhere from 400 cold cranking amps on the smaller batteries all the way up to over 1,500 for some of the larger and more expensive batteries.

You will need to conduct a car battery test using either a special battery meter (or a multimeter).  A fully 100% charged battery should register 12.66V or higher on your voltmeter.  If the voltmeter reading is below 12V, your battery is no longer good and it would be wise to replace your car battery.  If the reading is <11V, your car battery is about to die and you should change your car battery right away.

13.8 to 14.5V or more while idling.  If your alternator gives a output reading of less than 13.8V, it is considered weak and may not be able to properly charge your car battery.  This may result in the dreaded “car can’t start” situation and you should visit your car workshop as soon as possible to service/replace your alternator.  If you replace your car battery with FastFix, we will test your alternator and will advise you if servicing/replacement is recommended. We know of workshops who specialize in alternators and can provide recommendations – available on request.

These are new generation of car battery designed so that they do not require any special maintenance by owners.  Unlike older batteries, there is no need to top these up with distilled water. These batteries are also sometimes known as VRLA (valve regulated lead-acid), sealed batteries and sometimes “dry cell”. FastFix supplies only maintenance-free car batteries.

EFB batteries are an enhanced version of standard wet-flooded technology. They are designed to meet the latest OEM vehicle demands and factory fitted into vehicles with Start Stop systems. The primary benefits of EFB technology are improved charge acceptance and greater cyclic durability when operating in a reduced state of charge (typical of Stop Start applications). As an approximation, EFB batteries will provide 85,000 engine starts, compared to 30,000 starts from standard flooded product.

Some troubleshooting is required and FastFix can help.  There are many reasons why a car can’t start. But most likely it is due to either a dead / flat car battery or a starter solenoid (ie. ignition) issue. The following are the 3 scenarios where it is likely due to a car battery drained/failure.

/*If your battery is older than a year and you hear either no sound or a series of clicking sound when you crank your car – it is almost certain that it is due to a dead car battery. Call FastFix now – we will come and rescue you.
  • If you forget to turn off your headlights or other electronic gadgets, there is also a chance that your battery is drained / flat and need a jump start. If there are other drivers around with jump start cables, they may be able to help. Do your own jump start only if you are familiar with the process. Remember that the sequence of connecting the cables is important. If you are not sure or if your car is precious to you, call FastFix. We know how to do a professional job.
  • If you had not driven the car for an extended period (more than a few days), it is also possible that your car battery is drained / flat. In this case, you may also require a jump start. After successful jump start, you should drive your car for at least 20 minutes (at least 60km/h) for the alternator (charging system) to charge your battery. Call FastFix if you need help, we will not only jump start your car, we will check the condition of your battery and also test your alternator and give you useful tips.

    Usually within 45-60 minutes if our mechanics are not on rescue jobs.  If they are, we will advise ETA (estimated time of arrival) to within a 30 minute range.

    Usually within 20 minutes unless your car had been modified and if battery is corroded. This total time includes the time to give you an overview of the process, the actual replacement as well as testing your newly installed battery and your car’s alternator (charging system). Where time permits, we will also share tips on maintenance of car’s electrical/battery system.

    Usually no – unless your battery is 100% flat.  For continental cars and those that support a backup power source, we will set up a backup battery to power your car while we swap out your existing car battery – this will ensure that no settings are lost in the process. This is on a best effort basis as there may be rare situations where the settings will still be lost despite our best efforts.

    We Prefer Amaron.  We prefer Amaron maintenance-free (MF or dry cell) car batteries. Amaron is the market leader in Singapore and used by 1 in every 2 motor vehicle on the road. It is also the battery of choice for public transportation (taxis) and other government and military mission critical vehicles.  We also carry a small quantity of Hoppecke car batteries to cater to continental (BMW, Mercedes, Audi, Volkswagen) car owners.
