Multi Battery Tester - ZTS MBT-1

Can this test 1.2v rechargeable ni-cad batteries? the 1.2v test button is only labeled for ni-mh batteries.

Are the testers offered by the seller the latest MBT-1 version that is labeled for testing CR1620 batteries?

This device is much more expensive than others: is it worth it?

Is this device UL (or similar) listed?
