Westward 3Z634 200 A Load Tester

The Westward 3Z634 is a new electronic battery load tester built for 12 V and 6 V systems. It applies a 200 A load and reads up to 2 000 A cold cranking amperage on an analog display. The case is hardened steel and the unit ships without tester batteries. Technicians use it to verify starting battery condition in automotive and light commercial fleets.

Suits 12 V and 6 V starter batteries only

Workshops checking standard lead-acid starter batteries up to 2 000 A CCA will find the range adequate. Buyers who need to test higher voltage packs, lithium chemistries, or deep-cycle banks above the stated CCA window should look at other equipment. The analog meter also means users wanting digital data logging or automatic pass/fail readouts will need a different instrument.

200 A fixed load at 6 V to 12 V DC

The single deciding specification is the 200 A load amperage combined with the 6 V to 12 V DC input window. If the battery under test falls inside that voltage range and the required load current is 200 A, the tester matches the job; otherwise it cannot perform the required discharge test.

Questions about this item

Does the Westward 3Z634 tester need its own power source to run a load test?

No, the unit draws the 200 A load directly from the battery under test and requires zero internal batteries.

Can I keep using my 6 V and 12 V lead-acid batteries with this 200 A load tester?

Yes, it tests both 6 V and 12 V systems across a 20 A to 2 000 A CCA range.

How do I confirm the Westward 3Z634 is giving a valid reading after I connect the two leads?

Apply the load for the recommended interval and watch the analog needle; a steady position within the green band means the battery meets its CCA rating.
