Reliable Backup Power for Everyday Electronics

Its 850VA / 450W capacity makes it a strong choice for home-office and small-business users who need protection from short power outages and utility disturbances.

Nine NEMA 5-15R Outlets

The BE850G2 provides nine NEMA 5-15R outlets, giving users ample connectivity for computers, displays, networking equipment and other compatible devices. Transformer-block spacing helps accommodate bulkier power adapters without unnecessarily covering nearby outlets.

Dual USB Connectivity

The UPS includes two USB ports for compatible devices. USB connectivity can also support UPS management functionality where supported by the connected system and APC software.

Automatic Battery Self-Test

Periodic automatic battery self-testing helps identify batteries that may require replacement before they become unavailable during an outage. Battery failure and disconnected-battery notifications provide additional warning for preventive maintenance.

Hot-Swappable, Replaceable Battery

The BE850G2 uses sealed lead-acid VRLA battery technology and supports hot-swappable battery replacement. The design allows the battery to be replaced when it reaches the end of its service life, helping extend the usable life of the UPS itself.

Cold-Start Capability

Cold-start capability allows the UPS to provide temporary battery power even when utility power is unavailable, which can be useful when access to essential electronics is required during an outage.

Adjustable Voltage Sensitivity

Adjustable voltage sensitivity allows the UPS to be adapted for different utility environments or compatible generator applications, helping reduce unnecessary transfers to battery when incoming power conditions fluctuate.
