Battery Testers, Battery Monitoring and Battery Management for Stationary Battery Systems
For 40 years, we have been developing and manufacturing battery testing technology and battery monitoring systems for professional users.
G. Jost electronic stands for mobile battery testers, stationary battery monitoring and battery management systems for UPS, industrial and safety battery systems — from on-site measurement and continuous monitoring to central evaluation and documentation in CS-Manager.
Since 1986 · In-house development and manufacturing · For qualified electrical professionals · CS-Manager software available free of charge
TMC-2001RTS Battery Tester
Mobile battery tester for standardized test procedures, precise internal resistance diagnostics and professional on-site battery maintenance.
Voltage, Rel and Rct measurement · Guided test workflow directly on the instrument · Limit monitoring during measurement · Connection to CS-Manager for evaluation and documentation
TMC-2001RTS
More diagnostic information than a classic 1000 Hz measurement
The TMC-2001RTS detects not only ohmic changes. With its additional Rct diagnostics, it also makes electrochemical abnormalities visible.
Batteries are electrochemical systems — their diagnostics should therefore also reveal electrochemical changes.
CS-Manager Software
Central battery management software for data administration, maintenance route planning, measurement analysis and maintenance documentation.
Battery Management Software — CS-Manager
CS-Manager
Manage sites, battery systems, measurement series, limits, maintenance routes and reports centrally — as a single-workstation solution or server-based solution for multiple users.
Preview: CS-4001/127
Available from August 2026: the newly developed successor to the proven CS-4001 battery scanner — fully integrated into the CS-Manager software.
Accessories for Mobile Use
TMC-IRCOM (4x4cm)
For areas where wireless communication is not permitted or not desired, the TMC-IRCOM external infrared adapter enables data communication without radio transmission.
TMC-Protector
A practical protective cover for our TMC-2001RTS battery tester, also available for retrofitting. The protective cover includes two strong magnets that provide secure hold on metallic surfaces in both vertical and horizontal orientation. Openings at the outer corners allow flexible attachment of a carrying strap.
90° Test Probes
Right-angle and straight Kelvin test probes are available. They are robust and equipped with easily replaceable Kelvin contacts. These test probes complement our range of Kelvin clamps and straight Kelvin test probes.
The connector plugs fit only our mobile RTS battery testers.
