Battery Health Analysis

The Peak 1220 tester evaluates 12V lead-acid batteries from 100 to 2000 CCA. It measures voltage, internal resistance, state of charge and state of health. The tool works on flooded, AGM, gel and EFB types in cars, trucks, motorcycles, boats, ATVs and RVs. It suits owners who want a quick diagnosis without removing the battery.

Handheld Plug-and-Play Operation

The unit weighs 0.29 kilograms and measures 5.06 by 2.85 by 0.87 inches. It connects directly to the terminals with the supplied clamps and cord. No external power source is required. Reverse-polarity protection and a spark-proof design allow safe use on installed or bench-mounted batteries. The tester frees you from a separate load bank or charger for basic checks.

Replaces Guesswork and Shop Visits

The device replaces visual inspection or a simple voltmeter by delivering 0.01V accuracy and 99.9% reliability across SAE, EN, DIN, JIS and IEC standards. It also tests alternator ripple, loaded and unloaded voltage, plus cranking voltage and duration. The jump is worth it when you need to confirm charging-system health before a long trip or after a no-start event.

Questions about this item

Does the 100-2000 CCA range cover my heavy-duty truck battery?

Yes, the tester supports all 12 V lead-acid batteries rated from 100 to 2000 CCA including flooded, AGM flat plate, AGM spiral, GEL and EFB types.

Will the clamps get hot or the unit draw noticeable power during a full-day shop session?

The design uses no-heat connections and reverse-polarity protection, so the clamps stay cool and the tester draws only the tiny current needed for its 0.01 V measurement accuracy.

Do I need a separate power pack or vehicle battery to run the 1220 tester itself?

No, the unit is battery powered and operates standalone — just connect the supplied clamps to the 12 V battery under test and it works immediately.
