Expanded Metal Technology (EMT)
Expanded Metal Technology (EMT) is a unique process in the manufacturing of Totachi batteries. Modern battery technology involves the use of a lead-calcium alloy in the production of battery plates, proven to deliver increased reliability and longevity of an automotive battery.
Totachi uses 100% virgin lead when compounding the PbCa alloy, and during the production of accumulator grids, a method of continuous casting and stamping of plates is used, now known as “Expanded Metal”. The use of Ca/Ca technology significantly increases start-up power, and prevents the boil-off of battery acid to create a “maintenance-free” battery. EMT improves the battery’s resilience to self-discharge in an idle state, provides a longer shelf life, and offers high CCA in extreme temperatures.
