Questions about this item

Which capacity version of the 2-Power CQ42 battery should I choose for my HP laptop?

The 2-Power CQ42 is supplied in a single 5200 mAh, 58 Wh version rated at 11.1 V, so there is no alternative capacity to select.

What does the 58 Wh rating mean for daily runtime in my HP Pavilion or Presario?

A 58 Wh pack typically delivers several hours of mixed office use on compatible HP Pavilion G4, G6, G7, DM4 or Presario CQ42, CQ56, CQ57, CQ62 models, varying with screen brightness and workload.

What interface does the CQ42 battery use and what does it limit in practice?

The battery connects through the proprietary HP MU06/MU09 slot; it only fits laptops whose original battery matches the 12 cm left and 5.5 cm right mounting-hole spacing shown in the diagram.
