More InfoQuote

Hioki portable battery testers support the maintenance of UPS and storage batteries critical to the life support of all businesses.

The BT3554 battery internal resistance tester sets the standard for assessing the deterioration and remaining life of UPS and other lead-acid batteries by giving a complete diagnosis via battery resistance testing.

The specially designed L2020 Pin Type Lead further improves testing efficiency with an L-shaped tip that lets you reach deep into the battery racks to completely probe the terminals.
