Replacing Lead Acid Batteries

The most commonly used batteries for providing backup power for UPS equipment.

In the realm of mission critical applications, more often than not, it is a lead acid battery that provides backup power for the uninterruptible power supply it is supporting. The two predominant types are VRLA (Valve Regulated Lead Acid) and VLA (Vented Lead Acid).  If you are simply interested in replacing existing batteries with more of the same, you'll need to know what batteries you have now. 

The information on this page will not only help you identify the batteries that are currently installed in your cabinet, but also provide specific information on those batteries, such as runtimes, material and safety data sheets, and proper disposal. 

How to Identify Existing Battery Cabinet & Type

Information Included on a Battery Cabinet Label

If you purchased your battery cabinet from us, the label on the interior of the cabinet door circled in the photo below provides the necessary information for purchasing replacement batteries.  The image on the right shows a close-up of a representative label inside your battery cabinet.  Notice that the model number on the label identifies the pertinent specs for the batteries in your current cabinet.

In the event that you are not sure from whom your battery cabinet was purchased, it may still bear a similar type label containing the information above.  When the battery cabinet can be safely accessed, either take a photograph of the label or make a note of all of the information contained on it.  If the label is missing or not legible, taking a photo of a battery and its label will be helpful as well.  Additionally, the number of the batteries in the cabinet is useful information.

The battery shown at the left is a VRLA, which is a sealed battery and therefore can be mounted in various orientations.  There are two types of VRLA batteries in the market today:  AGM (Absorbed Glass Mat) and Gel.  We see many more applications of AGM than Gel in the mission critical market.

Battery Runtime Graphs

If you wish to explore different VRLA battery options in terms of run time, you may find this section particularly helpful. Simply click on the UPS of interest and then select the appropriate kVA range. You will find suitable batteries for that configuration with their corresponding run times. Be sure to scroll to see the notes below the graphs that identify not only the batteries reflected in the chart above, but also the cabinets that can house those batteries.

Battery Data Sheets

Run time should not be the only concern when considering a change in batteries.  Please also consult the data sheets below for other design parameters.

Important Material Handling Compliance

Batteries that are being replaced need to be disposed of properly in accordance with EPA guidelines.  Since they contain hazardous materials, it is unlawful to toss them into refuse that will end up in a landfill.  We would be happy to assist you with the disposal of your lead acid batteries.  Please feel free to contact us for more information. In addition, we recommend a review of your battery manufacturer's Safety Data Sheet with respect to disposal/recycling recommendations.  Please see links below for SDS sheets for batteries that we supply.

A Word About Wet Cells

Known properly as VLA (Vented Lead Acid), these batteries require more maintenance than VRLA.  As their name indicates, they are vented to the atmosphere and therefore require that their electrolytic fluid be monitored on a continual basis with water being added periodically to ensure that proper fluid levels are maintained.  They are typically rack mounted for easy access (as opposed to being installed in a cabinet).  VLA batteries require adequate ventilation and need to be installed in an upright position.   Obviously, they would not be suitable for regions that experience seismic activity.  They have a considerably longer life (up to 20 years) and are more resistance to overcharging than VRLA.  As such, they command a higher up front cost than VRLAs.
