At a Glance

Signs Your Honda Fit Battery Is Failing

Confirm the Battery Is the Problem
- With the engine off, a healthy battery reads about 12.6 volts. Below about 12.2 volts it is significantly discharged.
- Most parts stores will load test the battery for free.
- With the engine running, voltage should read roughly 13.5 to 14.8 volts. If not, check the alternator before replacing the battery.
- Clean corroded terminals first; a poor connection can mimic a dead battery.
A scan tool such as the YOUCANIC UCAN-II Pro shows live battery and charging voltage on supported models, which helps you tell a worn battery from a charging problem.
