We’re in the fourth week of national lockdown which means most of us are keeping safe by staying home more. That will likely mean you are not using your car as often, or only making short journeys. This can in turn mean that your car battery is not being charged regularly and fully, increasing the potential for damage to your battery. Batteries do not like being left discharged as it damages them and reduces the storage capacity.
- Engine is beginning to turn over more slowly on startup
When a battery becomes weak, the actual power it has to turn the engine (known as cold crank performance (Amps) or CCA for short) drops down and that will manifest itself in the engine turning over slower than before when the start is initiated.
- Rapid clicking sound on startup and the engine not turning
This is a sure-fire sign of battery deterioration. The battery has enough power to fire the starter motor solenoid, but not enough to actually turn the engine.
Whilst a battery may show 12v+ if tested with a multimeter, it’s the actual power that is important. Battery power is measured in Ah, which is why the label will clearly state the Ah figure and in most cases another figure as just ###A. This is the figure of the CCA and indicates how the battery will perform in cold start conditions. A higher figure indicates the battery will turn the engine quicker and for longer until the engine starts.
A battery with dead cells or poor power capacity will often charge quickly, however that is because only a small percentage of the storage is actually being recharged. So it will show 12v as mentioned, but the actual power is diminished and the battery requires replacing.
