Our 9-cell Dell Inspiron 15 Series battery has twice the battery life as the original 6-cell battery and can stay unplugged for up to 5 hours. Because of the additional cells, this battery protrudes slightly from the rear of the laptop but is still 100% compatible.

When choosing a replacement laptop battery, quality is everything. That’s why we use only the highest quality Samsung lithium-ion cells. Higher quality cells mean a faster charge, more battery runtime, and longer battery life. Batteries also use computer chips to communicate with the computer’s power and safety software that tells it when to charge and when to stop charging. We use only the highest quality Texas Instruments battery chips. Each battery is individually tested and is backed by a full 2-year warranty and 30-day return.

This Dell Inspiron 15, 1525, 1526, 1546 and 1545 battery is rated at 7800 mAh, one of the highest capacity Li-ion batteries on the market. The higher the mAh (milli-amp hour) the longer your battery charge will last. The 7800 mAh battery will still be compatible if your current battery has a lower mAh. It just means the new battery will last longer.
