A period of short, infrequent journeys or a length of time when a vehicle is not being used can cause its battery to fail rapidly. This is because:
- A battery is an electrochemical device which naturally loses charge over time
- It loses charge faster in higher spring and summer temperatures
- Alarms and electrical systems will drain it, even when the vehicle is turned off
- Shorter, infrequent journeys will take more charge away than the alternator is able to replace
- Over time it will drain more deeply causing failure due to internal battery damage (sulphation and acid stratification). This type of failure is service related and not due to a manufacturing defect. It is not covered by the battery’s warranty.
To keep on top of battery testing and warranty issues with vehicle batteries, use the GYT250 Battery and Electrical System Tester.
