Argus 2 battery keeps running out of power,

[betta_119420242788569]

one of my three Argus 2 batteries keeps running out within days, even though I charge it with an outlet and the solar panel is facing the sun. Could the battery be faulty? Reolink support has not contacted me yet, which could be due to the Pandemic.
Any thoughts on what could be wrong?

I had a battery that did that and found that one of the batteries had exploded. Once I got a hold of service, they replaced it quickly!
