Frequently Asked Questions - Intelligent LCD BRG850AVRLCD CyberPower
What is the difference between VA and watts on my UPS?
VA (volt-amps) represents apparent power, while watts represent real power. The ratio depends on the power factor (typically 0.6 for this model). So 850 VA × 0.6 = 510 W. Devices with PF above 0.6 may need more watts.
How long will my CyberPower BRG850AVRLCD keep my computer running during a power outage?
Runtime depends on the load. At half load (around 255 W), expect about 7 minutes; at full load (510 W), about 2 minutes. The LCD displays remaining battery capacity.
Can I replace the battery myself?
Yes. The battery is user-replaceable and located under a removable panel on the bottom. Disconnect the UPS from AC, remove the panel, disconnect the two leads, and swap with a new 12 V / 9 Ah battery. No tools are needed.
What information does the LCD screen show?
The intelligent LCD shows input/output voltage, frequency, load level (%), battery capacity, and alarm status. It also indicates when the UPS is on battery or AVR is active.
Can I connect the UPS to my computer for automatic shutdown?
Yes, this model has a USB connection (and serial port on many models) that works with CyberPower PowerPanel personal edition software. You can configure auto shutdown, schedule tests, and monitor power events.
How should I clean and maintain the UPS?
Keep the area around the unit clear and dust-free. Wipe the exterior with a dry cloth only. Do not use liquids or sprays. Periodically test the UPS with the self-test function. Replace the battery every 3 to 5 years.
Is it safe to plug a power strip into the UPS?
No. Plugging a power strip or extension cord into the UPS output can overload the UPS and circumvent protection. Only plug individual devices directly into the UPS outlets.
What is AVR and why is it important?
Automatic Voltage Regulation (AVR) corrects undervoltage (brownouts) and overvoltage without switching to battery. This maintains stable power and preserves battery life. The BRG850AVRLCD is a line-interactive topology with AVR.
How do I know when the battery needs replacement?
The UPS will sound a continuous beep during a self-test and the LCD will show a “Replace Battery” message. If runtime becomes very short even at light load, replace the battery.
What does the covered warranty include?
The UPS is covered by a 3-year limited warranty. CyberPower covers defects in materials and workmanship. The battery warranty is typically 3 years. Contact CyberPower support with your receipt for service.
