Analyzer Tester

Automotive Battery Tester?

Can anyone give me a little info on the Argus AA400 Battery
Analyzer as an overall testing unit. Quality , Reputation , Functionality
Reliability, and anything else I may have overlooked.
My toolbox has some vacancy.

Are you talking about a voltage tester? If so the brand you mentioned is not familiar to me. But as a general rule, the better ones for my usage, have been made by Sun Corp. they are very reliable and sturdy. good luck.
