Quick answer
A multimeter is useful for basic voltage checks, but it cannot tell the whole story of battery health. A proper battery tester can estimate CCA, state of health, and cranking behavior.
Best setup
For a home garage, keep both: a multimeter for electrical checks and a battery tester for battery-specific decisions.
Common mistake
A battery can show decent resting voltage and still fail under load.
