Storage Battery Systems Inc. offers a leading edge conductance battery diagnostic tester especially designed for the telecommunications & automotive/motive power industries that rely upon stationary dc power cells for their business operations. The SBS-4000 is a copmplete kit with I-R printer, I-R temperature probe; cable clamps, cable probes, probe tips & handheld CPU analyzer. Interface software with graphical trending is included to upload data from any of the 16 registers each with 480 test result entries. Consistent use of the SBS-4000 will allow you to identify those battery cells or jars that are approaching impending failure or have reached the end of their useful service life.
