Asus VivoBook Green Cell Battery 3600mAh (Li-Po 11.55V) - Ref. B31N1912 / C31N1912 (Refurbished)

Description

The Green Cell internal 3600 mAh replacement battery (references B31N1912 / C31N1912 / 3HWPP) is a refurbished spare part specially selected for the maintenance, refurbishment, and overhaul of the 14 and 15-inch Asus VivoBook laptop range (E410MA, E410KA, L410MA, E510MA, L510MA series). Intended for IT repair workshops, maintenance technicians, and B2B resellers, this refurbished battery is covered by a 3-month warranty, allowing users to restore the original battery life of Asus laptops while controlling workshop equipment costs.

Electrochemicaly, this refurbished module uses an assembly of 3 high-density Lithium-ion Polymer (Li-Po) cells of the Green Cell brand, delivering a capacity of 3600 mAh at a nominal voltage of 11.55V for an accumulated energy of 42 Wh. This architecture offers a perfectly stable voltage output on the motherboard and supports up to 500 complete charge and discharge cycles. The unit features an intelligent electronic management board (BMS - Battery Management System) responsible for active control of charging parameters. This controller protects the accumulator and the computer against overvoltages, deep discharges, short circuits, as well as the risks of thermal runaway.

The ultra-flat external casing is moulded from a high-density, heat-resistant insulating polymer, rigorously adjusted to the internal footprint of the Asus chassis. Installation is carried out under the lower cover of the computer and connects to the motherboard via a secure flat ribbon connector. The location of the metal fixing eyelets faithfully respects the original anchorage points to ensure perfect mechanical rigidity without exerting stress on the internal structure.

Workshop Advice & Usage

Before replacing the battery on an Asus VivoBook, completely turn off the laptop and unplug the mains power supply. After removing the screws from the lower cover and unclipping the plastic chassis using an opening spatula, it is essential to disconnect the used battery ribbon cable from its socket on the motherboard before removing the retaining screws. Do not use a metal tool to pry out the Li-Po cells during extraction. During initial setup in the workshop, perform a complete calibration cycle: charge the refurbished battery to 100%, then let the device discharge gradually down to 10-15% before carrying out an uninterrupted recharge connected to mains power.
