Yuasa EN Range
*Final Voltage: 1.75V/cell @ 25o
The Yuasa EN Overview document can be found here (EN Overview doc).
Yuasa VRLA battery’s unique construction and sealing technique ensure no electrolyte leakage from the case or battery terminals.
Yuasa EN battery containers and lids are made from a flame retardant plastic material (Oxygen Index 30).
Yuasa EN batteries have been specifically designed so that different capacities within the EN range can be paralleled for a common system. This greatly extends the selection of capacities that can be achieved, providing great options for configuring and expanding back-up power requirements for applications.
Electrolyte Suspension System
All EN batteries utilise Yuasa’s unique electrolyte suspension system incorporating a micro fibre glass mat to retain the maximum amount of electrolyte in the cells. The electrolyte is retained in the separator material and there is no free electrolyte to escape from the cells.
The design of Yuasa EN batteries incorporates the very latest oxygen recombination technology to maximise the efficiency of operation, eliminating the need for water to be added during its operational life.
Due to the perfectly sealed construction and the recombination of gases with the cell, the battery requires minimal maintenance while in service.
The combination of the sealed battery construction and Yuasa’s unique electrolyte suspension system allows operation in any orientation, with no loss of performance or leakage of electrolyte (excluding continuous use in inverted position).
Valve Regulated Design
All EN batteries are equipped with engineered low pressure venting system. This system allows the release of excess gases within the battery which can occur under charging conditions. The system automatically reseals when the internal pressures within the battery return to specified levels.
: EN batteries should not be charged in a fully sealed container. For further information please contact your local Century Yuasa representative
Lead Calcium Grids
The heavy duty lead calcium alloy grids provide an extra margin of performance and life in both shallow cyclic and float applications, offering unparalleled recovery from deep discharge.
The heavy duty lead calcium tin alloy grids provide excellent resistance against corrosion. The expected service life is 10 years in stationary floating applications.
The specially designed separator material provides a very efficient insulation between the negative and positive plates within the battery. This insulation prevents inter-plate short-circuits and inhibits the shedding of the active material on the plates, thereby maximising the life of the battery.
Long Shelf Life
The extremely low self-discharge rate of the Yuasa EN batteries allows these batteries to be stored for extended period of up to one year at normal ambient temperatures.
Wide Operating Temperature Range
The industrious design of the Yuasa EN range provide for use over a broad range of temperatures, providing there is some flexibility in both system design and location.

All Yuasa lead acid batteries have the potential to be recycled. In most cases, better than 90% of Yuasa lead acid batteries can be recycled. For further information on Century Yuasa’s recycling program, please visit the Recycling section
