Replacement battery for Inspiron 13 14 15 17

This Dr. Battery MPL05308P-10 is a new lithium polymer pack rated at 11.4 V and 3400 mAh. It replaces Dell part numbers RRJDX T2JX4 WDX0R Y3F7Y YRDD6 0FW8KR across Inspiron 13 5368 5378 5379 2-in-1 14 7460 15 5538 5565 5567 5568 5570 5578 2-in-1 5579 2-in-1 7560 7569 7570 7579 and 17 5765 models. Buyers who need a different voltage or connector layout cannot use this pack.

Sustained discharge with smart chip control

The built-in smart control chip manages charge current and discharge pacing to reduce heat during long sessions. Protection circuits guard against short circuit overheat and overload so the cells stay within safe limits when the laptop draws steady power. Capacity is listed as 3500 mAh or 42 Wh for reference. Users who require hot-swap capability or external charging cradles will not find those features here.

Fixed 11.4 V lithium polymer interface

The pack delivers a single 11.4 V output through the original Dell connector so it fits the motherboard header without adapters. Lithium polymer chemistry limits the maximum charge voltage to the factory specification and the smart chip enforces that ceiling. The one-year warranty covers defects in materials and workmanship. Systems that expect a different cell count or a proprietary authentication handshake will not recognise this battery.

Questions about this item

Does the 11.4 V lithium-polymer pack run hot during all-day use?

The battery uses lithium-polymer cells rated at 11.4 V and 3400 mAh; normal operation stays within Dell thermal limits for the listed Inspiron models.

Must my Dell already have the original RRJDX or T2JX4 battery installed for this replacement to fit?

This unit replaces Dell part numbers RRJDX, T2JX4, WDX0R, Y3F7Y, YRDD6 and 0FW8KR across the compatible Inspiron 13, 14, 15 and 17 series.

Will the smart control chip work with the charging circuit in my older Inspiron 15 5538?

The built-in chip provides short-circuit, overheat and overload protection and is designed for the 11.4 V charging system used in the 5538 and other listed models.
