Load and Conductance Testing
Tested under load, not just for resting voltage. A battery showing a healthy figure at rest can still fail to turn an engine over on a hot afternoon.
Cars that stand between drives with enough electronics to flatten themselves while they do it. Al Zaabi Autocare carries out Aston Martin battery testing and replacement in Mussafah, Abu Dhabi, across the DB11, DBS, Vantage, DBX and Rapide.

Send the model and the mileage. We come back with the scope and a price before any work starts.
Heat kills batteries here, not cold. A battery that was fine in January fails without warning in June, and the charging system is tested with it rather than after it.
Open the full list below for everything a Aston Martin battery replacement covers, and what each part of it involves.
Tested under load, not just for resting voltage. A battery showing a healthy figure at rest can still fail to turn an engine over on a hot afternoon.
Alternator output, regulation and ripple measured. A battery that keeps failing is usually being killed by the charging system, and replacing it again does not help.
Where the car goes flat while standing, current draw is measured circuit by circuit until the one that will not go to sleep is found.
Right capacity, right cold cranking figure, right terminal layout and the right technology. Stop-start cars need AGM or EFB, and a standard battery in one of them is a false saving.
Most modern cars have to be told a new battery has been fitted so the charging strategy resets. Skipping it means the car charges the new battery as though it were the old, worn one.
Terminals cleaned and protected, clamps and earth straps checked. A corroded earth imitates a dead battery convincingly and costs nothing to put right.
Clamped down properly with the vent routed where the design puts it. A battery that can move is a short circuit waiting for a speed bump.
Cranking current is measured while the engine turns, because a heavy starter draw looks exactly like a weak battery and is not.
Power is maintained during the change where the car needs it, so the radio, the seat memory and the learned values survive the job.
The old unit is taken away and recycled through the proper route rather than left in the boot.
Fitting a battery takes minutes. These are the things that decide whether the new one lasts its life or half of it.
A battery repeatedly discharged by standing does not recover. It is load tested rather than judged on what it reads after a run.
Where a car flattens itself while parked, current draw is measured circuit by circuit rather than answered with another battery.
Right capacity, right terminals and clamped down properly, with the vent routed as the design intends.
A proper conditioner does more for a car that is parked most of the time than any battery upgrade will.
Low voltage makes several modules log faults at once, which looks alarming and is usually one tired battery.
Test first, because a new battery does not fix a charging fault.
Battery under load, alternator output and, where the symptom is a car that goes flat standing, parasitic draw.
The correct type and capacity for the car, with the reason if it is dearer than the one on the shelf.
Fitted, clamped and vented correctly, terminals cleaned, and the battery registered to the car.
Charging voltage checked with the engine running and the result recorded, so you leave with proof rather than with hope.
What you drive away with after a Aston Martin battery replacement, beyond the invoice.
First turn of the key on a hot afternoon, which is the only test of a battery anyone actually cares about.
The technology and capacity the car's charging strategy was built around, rather than whatever fitted the tray.
The car charges the new battery as new, which is what decides whether it lasts its life or half of it.
If the alternator was what killed the last one, you find out now rather than in six months with a second dead battery.
Low voltage makes modules log faults across the car. A healthy supply clears a surprising number of unrelated warning lights.
Memory maintained through the change, so the car comes back with its presets, its clock and its learned values intact.
Find yours below. If it is not listed it is still covered, so call the workshop and ask.
Most batteries give about a week of warning. Some give none, which is why they are tested rather than waited on.
The engine takes longer to catch than it used to, most obviously first thing or after the car has stood in the sun.
Once is a warning. Twice is a battery or a charging fault, and it will happen again at a worse moment and in a worse place.
Headlights that dip when the air conditioning cuts in, or dash lights that flicker at a standstill.
Several unrelated systems complaining at once is the classic signature of low voltage rather than of several broken systems.
The car has decided the battery is not healthy enough to restart the engine, and it is usually right.
Windows, mirrors and seats moving at half speed, worst when the engine is off.
A car that starts fine daily but is dead after a week has a parasitic draw, not necessarily a bad battery.
Heat is what ages a battery here. Age alone is reason enough to have it tested rather than trusted.

What Aston Martin owners ask before booking a battery replacement in. If yours is not here, call the workshop and ask.
Very often, yes. Low voltage makes several modules complain at the same time, which looks like a serious electrical problem and is usually one battery at the end of its life.
If it stands between drives, a proper conditioner is the single most useful thing you can do for it, and it costs far less than the batteries it saves.
Considerably less than the same battery would in a cooler country, because heat is what wears them out. It is worth having the battery tested every year rather than waiting for it to strand you.
Both are built for stop-start cars and for the deep cycling that comes with it. AGM holds its electrolyte in a glass mat and takes the hardest duty, and EFB is a reinforced flooded battery for lighter stop-start systems. Which one your car needs is set by its charging strategy, not by price.
On most modern cars, yes. The charging strategy is tied to the battery's age, type and capacity, and registering it is what makes the car charge a new battery as new. It takes minutes and it decides how long the battery lasts.
Either the charging system is not replacing what is used, or something is not going to sleep and is draining it while the car stands. Both are measurable, and replacing the battery a third time is not the answer to either.
