Jessica, cruiser owner in Naples Island asks
How do I know if my boat battery needs replacement?
- 
                            
Look out for weak engine starts, dim lights, electronics shutting down, or batteries not holding a charge. If your battery is over 3–5 years old, it’s time for a full test or replacement. We can test it on-site.
