HP ProBook Green Cell Battery 4400mAh (Li-Ion 10.8V / 11.1V) - Ref. CA06 / CA06XL (Refurbished)

Description

The Green Cell external 4400 mAh replacement battery (references CA06 / CA06XL) is a refurbished spare part specially selected for the maintenance, refurbishment, and overhaul of the HP ProBook 640 G1, 645 G1, 650 G1, and 655 G1 professional laptop fleet. Intended for computer repair workshops, network maintenance technicians, and B2B resellers specialized in refurbished IT equipment, this refurbished battery is covered by a 3-month warranty, allowing users to restore the full mobility of HP 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 10.8V (compatible 11.1V) for an accumulated 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 features an intelligent electronic management board (BMS - Battery Management System) responsible for the continuous regulation of the charging current. This controller ensures active protection against overvoltages, deep discharges, short circuits, as well as 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 the ProBook 600 G1 series, this module snaps directly into the external power bay without the need to dismantle the device. The guide rails and mechanical latches faithfully respect the original manufacturer specifications to ensure a firm hold with no mechanical play under the computer.

Workshop Advice & Usage

Before validating the order for a professional client, precisely confirm the generation of the HP ProBook: this CA06 battery is exclusively intended for the first generation (G1). It is not compatible with ProBook 640/650 G2 or later models. The installation of this removable battery is carried out with the power off and the mains adapter disconnected, by sliding the module into its bay until the locking latches click. During initial deployment in the workshop, the workshop advises performing an initial calibration cycle: charge the refurbished battery to 100% using mains power, then let the computer discharge gradually to about 10-15% before performing a full recharge without interruption.
