1. The battery isn’t charging properly
2. Too many short journeys
3. A fault draining power
These issues can often be corrected before replacement.
Signs After Five Years
Starting problems after five years usually indicate:
1. The battery is wearing out
2. Capacity is reduced
3. Replacement is likely soon
Mobile mechanics help confirm this with proper testing.
