Product Features & Customer Benefits

Tubular PlateProven 20-year service lifeExcellent cycling characteristics. Up to1,500 cycles to 80% DODMeets or exceeds DIN 40737-3 and 40744Compatibility with existing installations

Robust DesignImpact resistant SAN jarsLeak proof, tongue-in-groove jar-cover sealsResistant to common cleaning agentsElectrolyte level easily checkedEasy-to-clean surfaceExtremely long intervals between topping-up with

waterExcellent post seal design

Clear JarsSame material as standard single cells, SAN (styrene

acrylonitrile)Provides crystal clear viewing of the cell plates,

bridges and electrolyte.

Test Individual CellsExternal welded connections between individual cells allow for testing individual cell voltages, internal resistance or conductance, and monitoring individual cells during load testing

External Welded ConnectionsExternal welded connections between individual cells allows on site “by-pass” or the use of jumpers to exclude a bad cell from within a block

The MESA Energy Block range consists of OPzS monobloc batteries conforming to DIN 40737-3 and 40744. They are suitable for use in DC power supply installations of every kind. The batteries have a long watering interval, and typically need topping-up only once a year throughout their operating life. The combination of lead-selenium alloy with tubular plate construction creates the longest service life alloy battery in the world.
