Questions about this item

What comes in the box and do I need any extra parts to install this MPL08217P-26 battery?

The package contains the 6-cell lithium-ion battery only. No additional cables, tools or adapters are required for installation.

Should I choose this 4400 mAh 10.8 V version or look for a different capacity for my HP G61?

This model matches the original 4400 mAh / 48 Wh specification listed for the G61 series. Select it when your original battery shows the same voltage and capacity.

What does the 10.8 V rating mean once the battery is fitted in my laptop?

It supplies the same 10.8 V output the original HP battery provides, so the laptop's power management sees no difference and charges normally.
