I have a HP DV4 1412TU laptop purchased in india. Now my concern is can i replace my laptop battery of 10.8 v 4200 mAh and 47wh rating with a 10.8 v 4400 mAh battery?

Will it affect my laptop's performance, or risk damaging it?

Changing the wattage of the battery could have major detrimental effects on your system. When produced, the hardware within is meant to work with only a specific power level with a certain level of margin. The laptop may seem to work fine for now, but over time it could very well cause severe irreparable damage.
