Lead Acid Chemistry Limits Runtime And Cycle Life

Lead acid cells deliver dependable backup power but offer lower energy density and fewer deep discharge cycles than other chemistries. Runtime is fixed by the 650VA UPS rating, so extended outages will exceed the capacity these two cartridges provide.

Questions about this item

Should I buy the 2 pack or look for a single cartridge?

The 2 pack supplies both 12 V cartridges the BK650X06 requires, so you replace the full set at once and keep the runtime balanced.

What does the 650 in the UPS model tell me about these batteries?

The 650 refers to the UPS rating, not the battery capacity; each 12 V cartridge delivers the voltage the BK650X06 expects for its rated backup time.
