Does 14.6V battery replacement work for 14.8V original ? [Inspiron 5559]

I have purchased a replacement battery for my Inspiron 5559 Laptop. On checking specs, the only difference I could understand was that the old one was 14.8V and the new is 14.6V. Both have a capacity of 2700 mAh.

I have also observed that sometimes its charge seems to be falling while I am using and charging the laptop together.

Is the new battery compatible, or could it be causing performance issues or damage to the hardware?
