The most commonly used batteries for providing backup power for UPS equipment.
Historically, lead acid batteries have provided backup power for an uninterruptible power supply in the realm of mission critical applications. The two predominant types are VRLA (Valve Regulated Lead Acid) and VLA (Vented Lead Acid) batteries. Careful and timely maintenance is essential to a reliable and efficient UPS. This includes annual and semi-annual maintenance checks and knowing when to replace batteries. Mitsubishi Electric provides replacement batteries for our UPS systems, whether you want to replace existing models with more of the same, or make a change. But first, you'll need to know what batteries are currently installed in your system.
If you purchased your battery cabinet from Mitsubishi Electric, the label on the interior of the cabinet door circled in the photo below provides the necessary information for purchasing UPS battery replacement. The image on the right shows a close-up of a label inside the battery cabinet. The model number on the label identifies the pertinent specs for the current batteries.
If you did not purchase your original cabinet from us, it may still bear a similar type label containing the information above. When the battery cabinet can be safely accessed, take a photograph of the label or make a note of the information contained on it. If the label is missing or illegible, take a photo of a battery and its label, and note the number of the batteries in the cabinet.
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.
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.
Now that you know what type of battery cabinet you have, it’s time to consider the right UPS battery replacement. There are a number of alternative energy solutions available for UPS batteries beyond traditional lead acid models. You could replace a lead acid battery with a lithium ion battery or a pure lead battery. Each has different benefits and considerations with respect to runtime and material handling. When it comes to UPS lead acid battery replacement, Mitsubishi Electric can help you make the right choice.

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.
Batteries being replaced need to be properly disposed of 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 also recommend a review of the disposal/recycling directions in your manufacturer’s Safety Data Sheet.
Contact us for more information around how Mitsubishi Electric can assist with the disposal of your lead acid batteries, and review our batteries’ Safety Data Sheets below.
Please find below the (Material) Safety Data Sheets for the VLA (wet cell) batteries that we sell.
Known properly as a VLA (Vented Lead Acid) battery, wet cell batteries require more maintenance than a VRLA battery. 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 a VRLA battery. As such, wet cell batteries command a higher up-front cost than VRLAs.
Whether replacing a lead acid battery with lithium ion or pure lead, Mitsubishi Electric can help secure the battery cabinet update you need to ensure your backup power stays up while batteries reach their end of life.
