HP EliteBook 840 G1 CM03XL Laptop Battery: Overview

This is a CM03XL replacement laptop battery for the HP EliteBook 840 G1 and many related EliteBook and ZBook models, for users whose old battery no longer holds a charge. It is a Li-ion battery rated at 11.1V and 4290mAh, with part number CM03 / CM03050XL.

The EliteBook 740, 750 and 840 G1/G2 generation is still widely used in Bangladesh as a used business laptop, and a fresh battery makes these machines practical again during load-shedding and away from the desk. It is a replacement (compatible) part with a 3-month warranty.

Key Features

  • 11.1V, 4290mAh Li-ion: the voltage and capacity class for this CM03XL battery type.
  • Part number CM03 / CM03050XL: easy to match against the label on your old battery.
  • Wide compatibility: covers EliteBook 740, 745, 750, 755, 840, 845, 850 and 855 Series (including G1 and G2), ZBook 14 and ZBook 14 G2 Series, ZBook 14 E7U24AA Mobile Workstation, and ZBook 15u and 15u G2 Series.
  • Restores unplugged use: lets you work, attend online classes or finish client work when power goes out.
  • 3-month warranty: covers early faults after installation.

Best For

  • Used EliteBook 840 G1 and G2 owners whose battery shows "replace" or drains in minutes.
  • Offices maintaining a fleet of older EliteBook or ZBook laptops.
  • Students and freelancers who need a few hours away from the socket.

Things to Check Before Buying

  • Check the part number on your current battery or confirm your exact laptop model in the compatible list.
  • This battery is fitted inside the laptop, so the bottom cover must be removed; a technician can do it if you are unsure.
  • Run a few full charge and discharge cycles at first so the battery meter calibrates properly.
  • Use a proper HP-compatible charger; a weak or faulty adapter can affect battery health.
