Replace your worn out battery with a brand new Dell M911 battery.

We use the highest quality lithium-ion cells that charge faster and last longer. We're so confident in the quality of our laptop batteries that each one is backed by a 2 year warranty and 30 day guarantee.

This M911 battery is compatible with the Dell Inspiron 1525, 1526, 1545, 1546 and 15 Series laptop models. It is also compatible with the Dell M911, RN873 and X284G part numbers.

This M911 battery contains the highest quality li-ion cells on the market from Samsung and components from Texas Instruments. An important specification to look for with rechargeable batteries is the mAh (mili amp hour) rating or Whr (Watt Hour). This M911 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.

You can expect about 2 hours to 3 hours of run time with this Dell M911 battery when new, depending on your energy use. If you are looking for even longer battery run times, check out our Dell Inspiron 1525 long run battery.
