Replacement battery for Dell Inspiron laptops

This 4-cell lithium-polymer pack is built as a direct replacement for compatible Dell Inspiron models. It delivers 15.2V output and 56Wh energy from a 3684mAh capacity. The unit weighs 0.6 kg and is sold as a single each.

Installation and common issues

Installation typically requires removing the bottom case screws and disconnecting the old pack before fitting the new one. Most failures come from loose connector seating or forgetting to calibrate the battery after the first charge. The 100% OEM-compatible design avoids fitment mismatches on listed models.

Capacity and voltage match

The decisive specification is the 3684mAh capacity at 15.2V, which must match the original battery label exactly. A different voltage or cell count will prevent the laptop from recognising the pack or charging correctly. Verify the OEM part number before ordering.
