Boron and battery noise when charging

I got a 3.7V 2500mAh Lipo battery plugged into the Boron and when it chargers it makes a very high pitch whining sound. Is this normal?

Typically, this is not normal.

What could it be?

When I searched online, there are incidences where the battery makes a high pitched sound when charging. It looks like the issue should not be with the Boron but the battery itself, where internal components might have degraded.
