What it is and who it fits

This 53Wh 15V 4-cell lithium-ion battery replaces Dell part numbers H5CKD, 7T8CD, TXD03, P129G, P101F, P102F and P126G. It fits Dell Inspiron 5300, 5301, 5400, 5401, 5402, 5406, 5408, 5409, 5501, 5502, 5508, 5509, 7300 2-in-1 Silver, 7306 2-in-1 Silver, 7405 2-in-1, 7500 2-in-1 Silver and 7506 2-in-1 Silver models, plus Latitude 3410, 3510 and Vostro 5300, 5301 laptops. It is not compatible with the black-chassis 7300, 7306, 7500 or 7506 2-in-1 variants.

Installation and common issues

The battery matches the original dimensions, so it slots into the chassis without modification. Disconnect the AC adapter and remove the bottom cover before unplugging the old pack; the connector is keyed and fits one way only. A frequent mistake is forcing the ribbon cable or forgetting to re-seat the connector fully, which can prevent the system from recognising the new cell.

Capacity, run-time and limits

Rated at 53Wh, the pack delivers typical ultrabook run-times for web browsing and office work; heavier loads such as video editing or sustained gaming will drain it faster. The cells are rated for up to 500 charge cycles before noticeable capacity loss. Built-in circuitry guards against over-current, overload and overheating, but the pack cannot be used in models outside the listed series or in the excluded black 2-in-1 units.
