Question

Why do some batteries fail quickly even if they test fine initially?

Answer

Intermittent failures often result from issues like sulfation, loose connections, or charging system faults that may not show immediately.

Explain

CHEPQ testers reveal hidden issues through comprehensive analysis, including sulfation, surface charge effects, and voltage drops from poor connections. Malfunctioning alternators or regulators can also cause unexpected failures.
