Dell Inspiron / Vostro Green Cell Battery 4400mAh (Li-Ion 11.1V / 10.8V) - Ref. J1KND (Refurbished)

Description

The Green Cell 4400 mAh external replacement battery (part number J1KND / 0J1KND) is a refurbished spare part specially selected for the maintenance, renovation, and refurbishment of a very wide range of Dell laptops from the Inspiron (13R, 14R, 15R, 17R, N4010, N5010, N5030, N5040, N5110, N7010) and Vostro (1440, 1540, 3450, 3550, 3750) series. Intended for computer repair workshops, network maintenance technicians, and B2B resellers specializing in refurbished hardware, this battery under a 3-month warranty restores the original battery life of Dell mobile workstations at a controlled equipment cost.

Electrochemicaly, this refurbished module uses an assembly of 6 high-density Lithium-ion (Li-Ion) cells of the Green Cell brand, delivering a capacity of 4400 mAh at a nominal voltage of 11.1V (compatible 10.8V) for a stored energy of 48 Wh. This configuration guarantees a perfectly stable voltage output on the motherboard and supports up to 500 complete charge and discharge cycles. The component embeds an intelligent electronic management board (BMS - Battery Management System) responsible for the continuous regulation of the charging current. This controller provides active protection against overvoltages, deep discharges, short circuits, and thermal runaway risks.

The rigid external casing is injected into a high-density ABS insulating polymer resistant to workshop thermal and mechanical stresses. Designed to fit under the chassis of compatible Dell Inspiron and Vostro laptops, this module clips directly into the external power bay without the need to disassemble the device. The guide rails and mechanical latches faithfully respect the original manufacturer's specifications to ensure a firm hold with no mechanical play under the computer.

Workshop Tip & Usage

Before validating the order for a professional client, precisely confirm the exact generation of the Dell Inspiron or Vostro: the J1KND reference is specifically adapted to chassis produced between 2010 and 2012. It is not compatible with newer Inspiron generations (such as recent Inspiron 15 3000/5000/7000 series which integrate internal flat-format batteries). Installation is carried out with the power off, AC adapter unplugged, by inserting the battery into its guide rail until the metal latches are fully locked. During the first deployment in the workshop, the workshop advises performing an initial calibration cycle: charge the refurbished battery to 100% under mains power, then let the computer discharge gradually to about 10-15% before performing a full recharge without interruption.
