The OptiMate TS120N Battery Level and Charging System Tester is a compact yet powerful diagnostic tool designed to help drivers and mechanics assess battery health and alternator performance with ease.

Key Features

Accurate Battery and Alternator Testing

The TS120N provides precise readings of battery voltage, charge level, and alternator output. It records the lowest starting voltage during engine cranking, helping identify weak batteries before they fail. When the engine is running, it measures the alternator’s charging voltage, ensuring it operates within the correct range—preventing both undercharging and overcharging, which can damage lead-acid or LiFePO4 batteries.

With a simple plug-and-test operation, the TS120N eliminates guesswork. It connects via SAE 2-pin connectors or traditional battery clamps (included), making it compatible with most vehicles. The backlit display clearly indicates battery status (weak, good, or fully charged) and alternator performance, ensuring quick and reliable diagnostics.

Weighing just 100g, this pocket-sized tester is ideal for roadside checks or garage use. Its sealed housing protects against dust and moisture, making it a dependable tool in any environment.
