Cyberpower 685AVR Replacement Battery

The UPS CyberPower Battery Replacement is widely considered a product which gets the job done during the span of its life but may have a shorter lifespan than advertised. It’s a powerful backup batter which does exactly what it’s advertised to do, although might do it for as long as advertisements lead consumers to believe. The product works as intended and at exactly the capacity and voltage it’s advertised to work at. There are few low marks from online reviewers, though a consistent complaint is the lifespan of the product and suddenness in which ceases operation past a certain point. These reviews are irregular, however, appearing to be in a small minority. The device is always sufficient to properly keep a uninterrupted power supply running for as long as needed and there are no consistent issues with its functionality. The company which makes the product cares about its customers and offers good, if not great, customer service. Altogether, there are no reasons to be overly cautious wary when purchasing a UPS CyberPower battery replacement.

Technical Specs


In Depth Review

The UPS CyberPower Battery Replacement has been used by many consumers on multiple review sites and the results are almost unanimously positive. Those who are most favorable of the product remark on its stable power production and durability, issuing no criticisms with the power and recommending it to anyone who needs a backup battery for their CyberPower UPS. Those who are not as high on the replacement battery note that it’s lifespan could be improved and that it may start to “leak” if not replaced within five years of use. Overall, both ratings and reviews skew positive to a degree which suggests the product is a must-buy for those in the market for a backup or replacement UPS battery.

In addition to the product being highly regarded by users, the company who makes it, CyperPower, is considered a great company to trust for satisfactory customer service and excellent knowledge expertise. The employees of CyperPower are knowledgeable and will often discuss the problems of their products with their customers. They will call back if they’ve missed a prior call and will talk through any issues with customers until the problem has been resolved.

The product is designed for the 685 AVR but is capable of use in a number of CyberPower products. It can be difficult, however, to discern where the battery fits and works, as online information is murky and reviews offer conflicting information on this front. It’s also difficult to find technical specs for the product beyond the height and weight, which makes it difficult to know if customers will truly get enough power for their needs. This said, there are few complaints about the product not supplying enough power for a range of CyberPower products and UPS devices.

The most common praise for the product comes in the form of saying that the power supply holds steady during even the most testing conditions, avoiding lack of operation during storms and other events that may test most uninterrupted power supplies. The reviews which claim that a simple storm or other such disruptive event could knock out the UPS with the CyberPower batteries inside are few and far between. The price is perfect for a device of this quality and durability, although those who have had good experiences with it noted that they wouldn’t mind paying far more. For the money it actually costs, however, you receive more than substantial piece of mind and the assurance that the batteries will not need any quick fixes or stop working during emergency events.

The backup UPS batteries are a great buy for those looking to have an emergency source of power for their uninterrupted power supplies, and their function is not marred by shoddy quality or lack of peace of mind. CyberPower consumers who find their devices dead will generally want this device to reboot their dead power supplies and can feel comfortable with their operation, as there are no moments of dead time. The only substantial complaint a few reviewers had was that the batteries would sometimes die before their five-year expiration. These reviews are not substantial in number, however, and are a direct counterpoint to the overall positive sentiment surrounding the product.


Ratings and reviews of this product offer one seamless, wholly positive picture of its quality. The backup power supply batteries are advertised accurately and will weather any storm they must to keep their devise online. This is a nicely designed product aesthetically though which is easy to comprehend and use, even for those without much experience with newer technology. CyberPower backup UPS batteries are the way to go for customers who want reliability and durability.
