B&K Precision 600B/601B Battery Capacity Analyzers

B&K Precision 600B and 601B Battery Capacity Analyzers are used to measure the remaining storage capacity of sealed lead acid (SLA) batteries. The handheld instruments are powered by the battery under test so that external power is not necessary. Both models test 12V sealed lead acid (SLA) batteries. In addition, the B&K Precision 601B model tests 6V batteries and displays the internal resistance of the battery as well.
