It is common for drivers not to notice the warning signs of a failing battery, as they can be subtle. Among the signals are the engine being a little slower to start, a slight clicking just before the engine starts, or fading dashboard lights. It is important to note that these symptoms may also indicate a faulty alternator. The best way to check if it is the battery at fault is to have a technician test it with a battery multimeter. A regular daily run for the car is not always sufficient to fully charge the battery, particularly if it has previously been run flat and not properly recharged. Also, vehicle battery checks during a service can be a reasonable indicator of whether a battery may need changing in the near future.
