6-cell 11.1V 48Wh replacement battery

This 6-cell lithium-ion battery delivers 11.1 volts and 48 watt-hours of capacity for select Dell Inspiron 13R, 14R, 15R and 17R models. It also fits several Dell Vostro 3450, 3550 and 3750 units. The black pack replaces original part numbers such as J1KND, 4T7JN and TKV2V.

Thermal and power characteristics

Lithium-ion chemistry produces minimal heat during normal discharge and the pack draws no power when the laptop is off. There are no moving parts, so operation is completely silent. The 48Wh rating supports typical office workloads without excessive temperature rise.

Sustained load behaviour

Under continuous demand the 5200mAh cell array maintains a steady voltage curve until the reserve is depleted. Capacity remains stable across repeated full cycles, avoiding the sharp drop-off seen in aged packs. The design suits users who keep their laptop running for long sessions away from mains power.

Questions about this item

How do I install the 6-cell 11.1V battery in my Dell Inspiron 15R N5110, and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch to unlock the old pack, remove it, insert the new battery until it clicks, then lock the latch; the step often missed is fully engaging the latch so the pack seats flush.

What maintenance or replacement will the 48Wh Li-ion pack need over time?

The 6-cell Li-ion pack will gradually lose capacity after several hundred charge cycles; when runtime drops below your needs, replace it with another compatible 48Wh unit — no other user-serviceable parts exist.

What limit appears first during sustained heavy use of this 5200mAh battery?

Under continuous load the pack hits its thermal and voltage sag limits first, reducing available runtime before the cells reach their cycle-life endpoint.
