4-cell 56 Wh Li-ion UPS battery

This replacement battery uses lithium-ion chemistry and delivers 56 Wh at 15.2 V DC. It is built to fit the proprietary form factor required by compatible notebook UPS units. The pack is rechargeable and meets WEEE, RoHS and Green Dot environmental standards. It suits technicians or owners restoring backup runtime to a supported device.

Who this suits and who should look elsewhere

It fits users who need a direct 4-cell 56 Wh replacement for a notebook UPS that specifies 15.2 V and the proprietary case size. Buyers whose equipment demands a different voltage, a higher watt-hour rating or a standard cell format will not be able to use this pack. Anyone without the exact model match should verify compatibility before purchasing.

The deciding specification: 15.2 V DC output voltage

The single figure that determines fit is the 15.2 V DC output. A UPS designed for another voltage will not operate correctly with this battery. Confirm that the original unit lists 15.2 V before ordering.

Highlights

  • 56 Wh capacity extends UPS runtime
  • 2 V output matches original spec
  • 3500 mAh Li-ion cells deliver reliable power
  • WEEE, RoHS and Green Dot certified
