1.2 Constructions of Lithium Cells
EEMB offers a complete range of primary lithium manganese dioxide cylindrical
cells for memory backup and portable applications worldwide.
The cylindrical cell configurations, offer the high-capacity bobbin construction and
high-power spirally wound product. The bobbin construction is targeted at low to
moderate power requirements, dedicated for applications requiring up to a 10 year
operational life at 20
. Our spirally wound constructional product offers high-rate
discharge capability, with an operational life in excess of 5 years.
