Replacement battery for Dell Inspiron and Vostro

The myVolts J1KND is a 6-cell lithium-ion pack rated at 11.1 V and 48 Wh. It fits a wide range of Inspiron 13R, 14R, 15R and 17R models as well as Vostro 3450, 3550 and 3750 systems. Buyers who need a higher-capacity 9-cell option or a pack for newer Dell chassis will not be served by this unit.

Thermals and power behaviour

The battery delivers its rated 48 Wh at 11.1 V through integrated protection circuits that guard against over-charge, over-discharge and short circuits. Normal operation stays within the thermal envelope of the original Dell design. No active cooling or external power draw figures are provided by the manufacturer.

Upgrade context and fit

This pack replaces Dell part numbers such as J1KND, 4T7JN, 312-0233 and 312-0234. It restores original run-time for the listed Inspiron and Vostro models. The jump is worth it when the existing pack no longer holds a useful charge. It does not fit the MR90Y model or any system outside the declared compatibility list.

Questions about this item

How do I install the J1KND battery in my Dell Inspiron N5110 and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch, remove the old pack, insert the new 6-cell unit until it clicks, then charge fully before first use; the step often missed is the initial full charge.

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

The 6-cell Li-ion pack gradually loses capacity over time; plan to replace it when run-time becomes too short for your needs.

What limit appears first during sustained use of this 11.1V battery?

The 48Wh capacity sets the run-time ceiling; under heavy load the pack will deplete faster and trigger the built-in protection circuit to shut down.
