What to check before buying

Match the battery chemistry and rating standard to the tester settings and the battery label. State-of-health and cold-cranking results are estimates from a test, not a guarantee of remaining service life. The supplied sheet lists flooded, AGM flat-plate, AGM spiral and GEL batteries; lithium batteries and high-voltage EV traction batteries are not confirmed applications.

Ask about BT201 with your vehicle make, model, year, engine and target system, or battery type and rating for a battery tester.
