Batteries for your UPS Liebert

Batteries for UPS / UPS

Which battery does a Liebert need?

Which battery does a Liebert take? Each Liebert model uses a battery of a specific voltage, capacity and size, often several units connected in series. Pick your model and we tell you the compatible reference and how many units it needs.

Next step: choose your Liebert model

Once you select the model you will see the battery compatible with your Liebert uninterruptible power supply: voltage, capacity in Ah, dimensions, units required and price. If the reference has no published price, ask for a quote and we reply the same day.

Battery types for Liebert uninterruptible power supply

  • Sealed AGM: maintenance-free and spill-proof, suitable for indoor use and for travelling with the equipment.
  • GEL: more charge cycles and better behaviour under deep discharge and heat.
  • Deep cycle: built to be discharged and recharged daily, not for engine starting.

Frequently asked questions

It depends on the model: each Liebert uninterruptible power supply uses a battery of a specific voltage, capacity and size, and many models take several units in series. Select your model to see the reference specified by the manufacturer, how many units it takes and its price or quote.
Yes. We work with Trojan, MK and Kronobat: deep-cycle batteries with the same voltage, capacity and dimensions specified by the Liebert manufacturer, with equal or better performance. If a reference does not fit, we replace it at no cost.
Many machines run at 24, 36 or 48 V with several 6, 8 or 12 V batteries connected in series (voltages add up; the Ah capacity is that of one unit). The model page tells you how many units it takes. Always replace the whole set with identical batteries of the same age.
Not advisable. A starter battery delivers a lot of current for a few seconds; a deep-cycle battery has thick plates built to be discharged to 50-80% and recharged every day. In traction, cleaning or mobility equipment a starter battery lasts very few cycles.
Some references are not published in the shop: click "Request a quote" and we reply the same working day with price and lead time. Those with a price can be bought online and ship the same day if you order before 6:00 pm.
