High-rate AGM
for the
UPS minute.
When mains fails, a UPS battery has minutes to deliver. HR series tunes plate design for high-current discharge over 5 to 30 minutes — the duty UPS specifies and where rate-of-fall matters.
Tuned for high rate
Thinner plates with higher specific surface area. Optimised for short, hard discharges instead of slow cycle duty.
Rack-ready
Standard heights match cabinet U-spaces. M5 and M6 terminals depending on capacity.
Sealed VRLA
Maintenance-free. Low gassing under float. Multi-orientation install for tight rack environments.
UPS-grade testing
Constant-power discharge tested per IEC 60896-22. Watts-per-cell published for 5, 10, 15 and 30 minute durations.
Built to discharge fast. Specified by the watt, not the amp-hour.
HR series rates capacity in watts at the cell level — the metric UPS designers actually use. Plate count, separator porosity and grid alloy all favour high-current discharge over slow cycling. AGM separator and calcium-tin grids minimise water loss.
