There are two key components inside your battery pack to look for when buying a new computer battery. The quality of the battery’s lithium-ion cells and the quality of the computer chip set in the battery pack. This battery is built with the best components, not the cheapest.

This 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 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. Simply put, more is better. And yes, this battery is probably better than your original!

You can expect about 2 hours to 3 hours of run time with this Dell battery when new, depending on your energy use. If you are looking for even longer battery run times, check out our extended run battery for your Dell laptop (our DELL-83XT). The higher capacity battery cells inside this cartridge have an energy capacity of 5200 mAh. This battery will be compatible with batteries rated at 4400 & 4800 mAh capacities while providing up to 20% more run time.

This battery replaces the Dell Inspiron 1525 1526 1545 laptop series.
