Phoenix Contact is usually known for their interconnect products and wide range of terminal blocks, but they also have a range of uninterruptible power supply products. One of these products is 1274117 (277-1274117-ND), a battery pack for their QUINT line of UPS products. We’ve had some questions recently on whether the individual battery cells in this pack are replaceable, and if so what is the part number for the replacement?
The battery cells in this pack can be replaced after being worn down, though note that the battery pack is rechargeable. The replacement cells can be found available from DigiKey here: 1283116 (277-1283116-ND).
