Product link: Hioki BT3554

Product link: Hioki 3561

Hioki portable battery testers support the maintenance of UPS and storage batteries critical to the life support of all businesses. The 3551 is a 300 mΩ to 30 Ω/30V portable battery internal resistance tester suitable for testing high-capacity alkali and lead-acid storage batteries used in mobile devices.

Key Features

• For use with compact batteries such as NiCad and nickel-metal hydride

• Instantaneously diagnose degradation (PASS, CAUTION, FAIL) by measuring internal resistance and voltage *Operator must input the criteria for PASS/FAIL judgments according to the type of battery being measured.
