Do Nickel-Metal Hydride batteries make a quiet popping sound when recharging?
I am recharging my Ni-MH batteries today (Wii-motes eat them up fast!) and I was wondering if it is normal to hear a quiet popping noise coming from the batteries? it sounds like tiny bubbles popping--very similar to the sound carbonated drinks make after being poured out of the original container.
I believe this noise is a result of the reversing chemical reaction being created inside the battery. the batteries shown below are my exact brand and model.
Is anyone else experiencing this phenomenon? If so, do you think it is normal? Leave your thoughts, comments, and otherwise below! =D
