Update your Battery Storage Cabinet When You Update Your UPS

Equipment End of Life Considerations

As a general rule, the life expectancy of an uninterruptible power supply is between 15 and 20 years. When it is time to replace your UPS, you may also want to consider upgrading other areas, such as your batteries and your energy storage system - especially if you will be conducting a retrofit to accommodate the new equipment. When updating a battery storage cabinet, consider the following:

Will the retrofit project be a replacement, upgrade/expansion, or a new solution?

Where a replacement would swap out like-for-like, an upgrade could use larger batteries in the same battery cabinet or an expansion could add additional battery cabinets to the system. Upgrading a VRLA battery to a Lithium Ion solution would constitute a new solution.

What is your budget for the project?

In addition to capital equipment expense, maintenance costs for the life of the product should be considered, especially when comparing traditional VRLA to alternative solutions, such as lithium ion. Learn more about performing a total cost of ownership analysis.

What space is available?

Space is a crucial decision-making factor in the mission critical industry, whether the goal is to maximize white space or simply work with the limited space available. For a smaller footprint option, check out alternative solutions to traditional lead acid batteries.

Are there existing problems you are trying to solve?

Insufficient runtimes and insufficient power are two common concerns.

Our dedicated and experienced team can help you determine the best solution for your situation. Below you will find information about upgrading or upsizing your batteries and battery cabinets when you update your UPS, as well as additional resources about these peripherals.

Upsizing UPS Batteries: An Upgrade For your System

Gaining additional runtime is the primary reason many of our customers upsize UPS batteries.


Most batteries with greater runtime capacity are also physically larger and require more battery storage space. If your current battery cabinet cannot store the larger batteries you’re moving to, a new or retrofitted battery and energy storage system will be required.


We can help you get the right battery storage cabinet to match your new UPS. Whether leveraging an existing battery cabinet through a retrofit or opting for a new cabinet altogether, you’ll also need to consider connector compatibility, cable size and the possibility of re-wiring.


If you are unsure what batteries you currently have in place, utilize the existing battery cabinet to help make that determination.
