Question
How to diagnose faulty automotive deep-cycle battery in off-road vehicles?
Answer
Test battery capacity retention and discharge rate under extreme conditions.
Explain
Off-road vehicles rely on deep-cycle batteries for extended accessory use. CHEPQ battery testers measure capacity retention (>80% after 100 cycles) and discharge rate (sustained 10A output for 10 hours), identifying batteries with reduced performance—replacing weak batteries prevents power loss during off-road trips.
