Get longer battery life and improved laptop performance with a new HP CQ42 battery from LBE.

We use the highest quality lithium-ion battery cells and components that charge faster and last longer than cheaper lower quality batteries. Lower quality batteries can wear out in as little as 6 months. Our batteries can last up to 5 years! All batteries are individually tested and come with a 2-year warranty and 30-day guarantee.

This Compaq CQ42 battery is compatible with a wide variety of HP and Compaq laptops, including the Pavilion g4, g6, g7, g32, g42, g56, g62 and g72 series laptops. It is also compatible with the HP dv3-4000, dm4-1000, dv5-2000, dv6-3000, dv6-6000, dv7-4000 series models. A full list of compatible laptop models and battery part numbers can be found below.

This Compaq CQ42 battery is rated 5200 mAh - the highest rating available for a 6 cell battery pack. The higher the mAh rating, the longer your battery will run before it needs to be recharged. This battery is still compatible if your current battery has a lower mAh rating. It just means the new one will let you go unplugged longer! If you're looking for even longer runtime, see our HP Compaq CQ42 Long Run battery.

We are a family-run, US-based business with friendly and knowledgeable customer support to assist you. Don't hesitate to call if you need additional help in diagnosing power problems with your battery, ac power adapter or battery software.

All our products carry a full 2 Year warranty and every battery is charged and tested before it ships. If your laptop doesn't turn on when plugged-in you need to replace the adapter with a new HP Pavilion G series power charger.
