2V cells for
utility-scale
battery banks.
Stationary 2V AGM cells string into 24V, 48V and 110V banks for telecom, utility and industrial backup. Long design life. Individual cell replacement keeps total system lifetime longer than block-only solutions.
Long design life
Tubular and flat-plate 2V designs deliver 15 to 20 year stationary life under controlled float.
Cell-level replacement
Replace individual cells without retiring the entire bank. Lower total cost over a 20-year horizon.
Telecom and utility
-48V telecom plant and utility-grid backup. Sized for cabinet and floor-mount rack installs.
AGM construction
Sealed VRLA AGM with calcium-tin grids. Low water loss, low gassing under float, recombination chemistry.
2V cells. 20-year horizon. Replace one, not the bank.
2V AGM cells use thick tubular or flat-plate positive grids with high-purity lead-calcium-tin alloy. Float life of 15-20 years at 25°C is typical. Float voltage 2.23-2.27V per cell. Boost charge 2.40V max. Cell-by-cell test data provided for matched strings.
