V-Drop Technology - This unique AutoMeter feature utilizes a patented process to automate the measurement of voltage drop in the charging circuit during starter engagement to ensure vehicle systems are operating at peak performance.. This test occurs with minimal operator effort in the short period of time required for the engine to crank over and fire.. Autometers V-Drop Technology Prevents The Need To Connect Additional Probes And/Or Disable Ignition Or Fuel Systems To Engage In Excessive Engine Crank Periods.. In the event that your AutoMeter tester equipped with V-Drop detects an issue it will guide the operator through the diagnosis to identify which part of the circuit is causing the excessive voltage drop.

Battery Extenders will safely keep your battery at full charge on a continuous basis. Batteries not kept at full charge become sulfated which is the main reason for premature battery failure.
