10 Best Battery Backups 2025 in the United States

The Vertiv Liebert PSI5 Lithium Ion UPS is a robust uninterruptible power supply with a power capacity of 1920VA/1920W, making it suitable for protecting a range of equipment from power disruptions. Its line interactive design with automatic voltage regulation (AVR) helps maintain stable voltage levels, which is essential for sensitive electronics. The UPS outputs a sine wave, which is the cleanest form of power, ensuring compatibility with critical devices like servers and networking hardware.

With a form factor of 2U, it can be easily integrated into standard server racks, offering flexibility in installation. The unit boasts lithium-ion batteries, which last twice as long as traditional VRLA batteries, enhancing its reliability and reducing maintenance costs over its lifespan. Additionally, it offers a significant runtime of up to 8.6 minutes at full load and 19 minutes at half load, providing ample time to safely shut down connected equipment during a power outage. Recharging is quick, reaching 100% capacity in just 2.1 hours.

The UPS also comes with a 5-year standard warranty, including batteries, which underscores its durability. However, the unit is on the heavier side, weighing 52 pounds, and its dimensions (24.8 x 17.2 x 3.4 inches) may require adequate space for proper installation. It features a limited number of outlets and lacks an LCD display, which could be a drawback for users needing real-time monitoring. The Vertiv Liebert PSI5 is a dependable option for those needing a long-lasting and efficient UPS for critical applications, though it might not be the most user-friendly for those who require detailed visual interfaces.

The Vertiv Liebert GXT5 UPS is a robust choice for those needing reliable battery backup, particularly in sensitive environments like servers and networking. With a power capacity of 2000VA and 1800W, it provides ample support for essential devices without risking overload. Its online double conversion technology ensures a consistent sine wave output, which is crucial for maintaining the health of connected electronics.

One of its standout features is the colored LCD display, which offers a user-friendly interface for monitoring the UPS's status and battery life. Its programmable outlets allow for tailored management of connected devices, optimizing battery use based on your needs. The unit is also Energy Star certified, demonstrating higher efficiency, especially when running in eco-mode, which can contribute to lower energy costs over time.

The UPS is quite heavy at 58.7 pounds, making it less portable if you need to move it frequently. While it excels in providing power, the sealed lead-acid battery may require eventual replacement, which can be an added cost. Additionally, while the updated firmware reduces fan noise, some users may still find the unit’s noise level higher than desired in quiet environments. The Liebert GXT5 is ideal for anyone who prioritizes high power capacity and reliability, such as small businesses, data centers, or home offices with critical equipment. However, if you're looking for a lightweight or extremely quiet solution, you might want to explore other options.

The Eaton Tripp Lite Series 2200VA Smart UPS is a powerful and versatile battery backup solution ideal for both home and office use. With a power capacity of 2200 Volt-Amperes (VA) and 1920 Watts, it is well-suited for protecting a range of electronic devices from power interruptions. This unit provides a sine wave output, which is a high-quality power signal that is particularly beneficial for sensitive electronics and equipment. It comes with seven outlets, including four NEMA 5-15R and four NEMA 5-15/20R options, making it flexible for different plug types.

The device features Automatic Voltage Regulation (AVR), which corrects brownouts and overvoltages from 83V to 145V, ensuring stable power delivery without relying on the battery, thereby extending battery life and efficiency. The interactive LCD interface makes monitoring and managing the UPS straightforward, providing real-time updates on battery status and other critical metrics. Additionally, the unit can be mounted in a rack or used as a tower, offering versatility in different setups. It is also ENERGY STAR qualified, meaning it is energy-efficient.

The UPS includes USB, RS232, and EPO ports, and it has an option for a network card, which would be beneficial for network administrators. However, at 68 pounds, it is quite heavy, which may be a drawback for some users who need to move or install the unit in tight spaces. The product comes with a robust 2-year warranty that extends to 3 years upon registration, along with a $250,000 insurance for connected equipment, providing peace of mind against potential failures. Despite some minor drawbacks, such as its weight and size, this UPS offers strong power protection, making it a reliable choice for those needing solid backup power support.
