Swiss Charger case LED problem

[Omnomicus]

Hello,

I bought recently a Swiss Charger iPower case and I am experiencing the following problem:
The second LED from the left stays on all the time (as long as the extra battery is charged).

Haven't found any troubleshooting manual
Any ideas? Does it mean anything? Should I return it?
