High Power Density
Lithium-ion batteries can pack more power into smaller spaces.
Quicker Recharge
Get back to max capacity quickly after an outage with 100% capacity recharging in just 3 hours.
More Discharge Cycles
Lithium-ion batteries deliver up to 10x more charge and discharge cycles than VRLA batteries, further lowering total cost of ownership.
0.9 Output Power Factor
More usable power enables more connected loads, saving space and costs.
Wider Input Voltage Window
Prolongs battery life by allowing the UPS to maximize the use of utility power before transferring to battery when input exceeds specified limits.
