Foxsur Car Battery Tester 12V 24V AGM GEL SOH SOC CCA Capacity Diagnosis Tool

Foxsur Car Battery Tester Advanced Diagnostic Features

State of health monitoring assigns a percentage value representing battery condition relative to manufacturer specifications, helping predict battery lifespan and optimal replacement timing. State of charge display shows current energy level as a percentage, distinguishing between a fully charged battery needing no service and a partially discharged battery requiring charging. Cold cranking amps measurement reveals the peak current the battery can deliver at zero degrees Fahrenheit, the critical specification that determines starting success in winter conditions. Infrared technology measures internal battery resistance without requiring physical terminals inside the battery, a non invasive method that detects developing faults before external symptoms appear. Battery capacity analysis compares the battery’s current reserve capacity against original specifications, documenting degradation progression and validating whether warranty replacement is warranted for both 12V motorcycles and 24V commercial vehicles.
