Replacement Battery for Dell Inspiron 14 15 17

This 40Wh 14.8V lithium-ion battery replaces the original power source in compatible Dell Inspiron 14, 15 and 17 models across the 3000 and 5000 series. It uses four A-grade cells to deliver 2600mAh capacity and is built to CE, FCC and RoHS standards. The unit is brand new and intended for owners of listed Inspiron and Vostro laptops needing a direct swap.

Sustained Runtime and Charge Behaviour

The cell chemistry and circuit board are selected to provide stable output during extended use rather than only peak bursts. Low power consumption design helps the pack hold charge across a full work session, while the 40Wh rating supports consistent delivery for everyday tasks. Fast charge acceptance reduces downtime between sessions.

Compatibility Check Before Ordering

Verify your laptop model appears in the supported list, which includes Inspiron 3451, 3452, 3458, 3551, 3567, 5558, 5559, 5755, 5758, 5759 and Vostro 3458, 3558. Confirm the original battery part number matches references such as 453-BBBR, 6YFVW, VN3N0, GXVJ3, W6D4J, HD4J0 or 4WY7C. Ensure the battery bay uses the slide-tab retention method described for installation. Buyers needing a higher capacity pack or a different voltage should not order this unit.

Questions about this item

How much heat does the 14.8V 40Wh battery generate during all-day use?

The 4-cell 14.8V 40Wh lithium-ion pack produces minimal heat under normal loads; the integrated circuit board manages power draw to keep temperatures low.

What must my Dell already have for this M5Y1K battery to fit and work?

Your Inspiron 14, 15 or 17 3000 or 5000 series must use a 14.8V 40Wh pack — models such as 3451, 3452, 3458, 3551, 3567, 5558, 5559, 5755, 5758, 5759 or Vostro 3458, 3558.

Will the 14.8V 40Wh replacement charge correctly with my existing Dell 65 W AC adapter?

Yes — the 14.8V 2600 mAh cell configuration matches the original voltage, so the standard Dell charger regulates charge current normally.
