This GW252 battery contains the very best Li-ion cells on the market from Samsung. An important specification to look for with rechargeable batteries is the mAh (mili amp hour) rating or Whr (Watt Hour).

This GW252 battery is rated at 5200 mAh or 58 Whr. This is the highest rating available for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be recharged again. There are no compatibility issues if your existing battery is rated at 4400 or 4800 mAh or a lower Whr. It just means this battery will last longer than the original.

You can expect about 2 hours to 3 hours of run time with this Dell GW252 battery when new, depending on your energy use. If you are looking for even longer battery run times, check out our Dell 1525 long life battery.
