Replacement battery for Compaq Presario

This 6-cell lithium-ion unit is designed as a direct replacement for a wide range of Compaq Presario CQ and HP G, Pavilion DV and HDX laptops. It suits owners of compatible machines who need a new power source after the original pack has lost capacity. The black casing matches the factory appearance of the supported devices.

10.8 V and 4400 mAh capacity define runtime

The pack delivers 10.8 volts and 4400 milliampere-hours, yielding 48 watt-hours of stored energy. Runtime is limited by this capacity and by the power draw of the specific laptop model in use. The built-in smart control chip manages charging and discharging within these electrical limits to maintain safe operation.

Six cells in a black housing with OEM-style fit

Six lithium-ion cells are enclosed in a black shell shaped to match the original battery footprint for the listed models. The form factor allows the pack to latch securely into the existing battery bay without modification. Integrated protection circuits guard against short circuit, overheat and overload during daily use.

Questions about this item

Should I choose the 4400 mAh 6-cell version or look for a higher capacity?

The 4400 mAh 6-cell pack delivers 48 Wh at 10.8 V, matching the original specification for the listed Compaq and HP models; higher-capacity packs would be physically larger and are not required for these laptops.

What runtime can I expect from the 4400 mAh rating in daily use?

At 48 Wh the battery typically powers a compatible Presario or Pavilion for several hours of office work; actual time varies with screen brightness, CPU load and wireless activity.

Does the 10.8 V output match the charging circuit in my CQ60?

Yes, 10.8 V is the exact nominal voltage specified for the CQ60 and all other models listed, so the laptop's charging controller will recognise and charge the pack normally.
