MotorAid sell industry leading car & van BOSCH batteries…
Faulty or flat batteries are one of the most common causes of breakdown. Stop-start or short journeys don't give batteries the opportunity to recharge properly.
There are a few things you can do to prolong the life of your car's battery, but we can also help.
When we attend a vehicle with a flat battery, or suspected flat battery we don't just jump start the vehicle and send you on your way. MotorAid will always carry out a battery test and look for the cause of the problem first when you come in for service, or we offer this as a free of charge service “pop in” as and when you like.
Reasons for flat batteries
A flat battery is most commonly caused by
a lack of use or vehicle only used for short journeys
something has been left on (light(s) or a faulty component is draining the battery
a fault with the vehicle's charging system
a fault with the battery itself
Short journeys or insufficient use of a vehicle will shorten a battery's total life. This 'under charging' results in 'sulphation' if the battery voltage is allowed to remain below 12.4 volts. Sulphation is the hardening of the lead plates within the battery and it reduces the battery's ability to accept or hold a charge.
If you do only use your car occasionally and for short journeys it's worth investing in an intelligent charger/battery conditioner that can be left connected for long periods without risk of damage to the battery, otherwise known as a trickle charger.
Batteries can fail for other reasons too such as, excessive vibration, over charging, corrosion and temperature (extreme heat and cold).
How we deal with battery problems
When we attend a vehicle with a flat battery, or suspected flat battery we don't just jump start the vehicle and send you on your way. MotorAid will always look for the cause. MotorAid will
test the battery
check the vehicle's charging system
check for a vehicle fault that may be draining the battery, and
ask what sort of use the vehicle gets
MOTORAID breakdown & recovery vans carry the latest industry leading battery tester which uses Conductance technology to measure the health of a battery. Conductance battery testing has become the industry standard and is used by all of the major motor manufacturers.
For an accurate result a lead acid battery has to be tested in its 'rested state', i.e. before the engine has been started – once the engine has been run, voltage and resistances within the battery will change and this can affect the test result. This means the MotorAid will always start by carrying out a battery test.
MotorAid will connect the tester to the vehicle's battery or remote jump start points and enter the battery details – type and specification – into the tester.
The tester is pre-programmed with data which it compares with the readings from the battery on your vehicle so it can assess the condition.
The battery tester will then display and print the results of the test.
MotorAid will still check the charging system and check that nothing is draining the battery to ensure there are no other faults.
The detailed test result will include one of the following statements summarising the condition of the battery.
A car battery is made of several separate two volt batteries – called cells – joined together. Cells cannot be replaced individually.
The battery needs replacing as the tester has identified that the battery has a defective cell.
The tester has identified that the battery is no longer able to provide the required current and needs replacing.
'Charge and retest'
Ideally the battery should be fully bench charged and retested.
A weak battery is slow to accept a charge, but a good battery will accept a charge more readily. If the readings with the voltmeter and amp-clamp are within specification for the vehicle the original battery test will be repeated to make sure the battery did not just fail the initial test through lack of voltage.
This indicates that the battery is within specification but discharged.
MotorAid will check the charging system, check that nothing is draining the battery and if necessary investigate further the cause of the breakdown.
A jump start will almost certainly be required and the MotorAid will advise a full recharge as soon as practicable using a battery charger/conditioner.
The battery is within specification and in good condition. MotorAid will check the vehicle's charging system and will then investigate the cause of the breakdown.
We can supply and fit a new car battery at a time and location that’s convenient for you.
If you do need a new battery call MOTORAID for the latest prices on BOSCH batteries that can be supplied & fitted & the old one taken away for environmentally-friendly disposal.
