Top 10 Battery Backups Deals Right Now

The Vertiv Liebert PSI5 Lithium Ion UPS is a solid choice for those needing reliable battery backup, especially in office or small data center environments. It offers a strong output power of 1350W with a 1500VA rating, making it capable of supporting multiple devices during power interruptions. With three programmable outlets and a sine wave output, it provides stable and clean power suited for sensitive electronics. The lithium-ion battery is a standout feature, lasting twice as long as usual lead-acid types and reducing the need for costly replacements.

You can expect up to 7.5 minutes of runtime at full load, which is suitable for short outages, and a fast recharge time of about 2 hours to get fully ready again. Its size is quite compact for a rack or tower setup, but it does weigh around 41.6 pounds, so it’s not super light. The rotating LCD display adds user-friendly monitoring, and the 5-year warranty with advanced replacement offers peace of mind.

If longer backup times or more output ports are needed, this model may feel a bit limited. Nevertheless, its combination of lithium-ion technology, respectable power, and quick recharge make it a practical choice for users wanting low maintenance and reliable protection against power loss.

The CyberPower PR1500LCD Smart App Sinewave UPS System is a solid choice for anyone needing reliable battery backup for sensitive electronics, especially in office or server environments. With a power capacity of 1500VA/1500W, it can support various devices, from computers to network equipment, making it suitable for both home and professional settings. The UPS features eight battery backup and surge-protected outlets, allowing multiple devices to be connected simultaneously, which is a significant advantage for users with several critical electronics to protect.

One standout feature is the Automatic Voltage Regulation (AVR), which mitigates minor power fluctuations without draining the battery. This function is excellent for extending battery life and ensuring consistent power delivery. The multifunction LCD panel is another highlight, providing users with real-time data about their power conditions and can be relocated for better visibility, which is particularly helpful in complex setups.

The unit is designed for efficiency, but it is somewhat bulkier than other models in its category, which might be a concern for those with limited space. The optional SNMP/HTTP remote monitoring capability requires purchasing an extra accessory, which could add to the investment. The warranty period is quite generous at three years, including the battery, which reflects confidence in its durability. The CyberPower PR1500LCD is a robust UPS system well-suited for users needing dependable power protection, particularly in business environments, but potential buyers should consider their space and additional costs for full functionality.

The GOLDENMATE 1000VA/600W Lithium UPS is a solid choice if you need a reliable battery backup for devices like computers, network equipment, or telecom gear. It uses advanced Lithium Iron Phosphate (LiFePO4) batteries, which last much longer than typical lead-acid batteries—over 10 years and 5000 charge cycles. This means fewer replacements and lower long-term costs. With a power output of 600 watts, it can support small to medium setups that need clean, stable power, thanks to its pure sine wave technology. This helps protect sensitive electronics from common power issues such as surges, voltage drops, and outages.

The unit offers eight standard outlets that provide both battery backup and surge protection, giving you flexibility to plug in multiple devices. It also features an LCD screen that shows real-time info about battery and power status, making it easy to monitor without being technical. Safety is a strong point here, with multiple certifications and a smart battery management system that prevents overcharging, overheating, and other risks. The cooling system keeps noise below 50 dB, which is fairly quiet.

The UPS dimensions and weight are moderate—about 13 x 4 x 10 inches and 10.5 pounds—so it fits well in home or office spaces. While it has many outlets, all are the same type, so no USB or other port types. This UPS is well suited for users wanting a dependable, maintenance-free backup with a long battery lifespan, especially if you value safety and stable power for sensitive electronics.
