Single Load Dynamic Resistance
(S.L.D.R.)

S.L.D.R. (Battery Testing)

DHC developed the Single Load Dynamic Resistance (S.L.D.R.) technology of battery testing based on the industry standard.

The S.L.D.R is a DHC worldwide patented technology of battery testing. It simulates the cranking current to reflect the true condition of the tested battery in seconds and gives you a more accurate in-vehicle test result.

This is the best alternative solution of testing a battery in a traditional time-consumed 1/2 CCA load test and the DHC S.L.D.R technology has been widely used by global car & battery OEs for decades.

Conclusion

DHC's technology reflects the true condition of the tested
battery (the load test method is stated in BCI's service manual)
and gets a more accurate in-vehicle test result.

Competitor analyzes the tested battery condition with a probing
small signal, which may be affected by some in-vehicle electronic
devices, especially when the car just reaches the garage, in the
case that the surface charge may blind the tester.

What is the BCI industry standard of battery test?

Battery Council International (BCI) is a not-for-profit trade association formed to promote the interests of the international battery industry. BCI has more than 200 member companies worldwide engaged in every facet of the industry: lead battery manufacturers and recyclers, marketers and retailers, suppliers of raw materials and equipment, and expert consultants. As the industry's principle association, BCI's member services have a global impact.

BCI establishes technical standards for battery manufacturing and actively promotes workable environmental, health and safety standards for the industry as a whole.
