Component in alkaline battery pack

I have a battery pack for roller blinds that takes 12 AA batteries in series, in 2 columns of 6. There is an electronic component in the middle, green resistor-shaped with the code 2A15 (I think) on it. Is that a capacitor and what is its purpose in this use-case? The battery pack does not appear to be working and no voltage measured at the barrel connector. Can I safely remove the component and hardwire the 2 connectors? I have a photo if there's a way to upload that.

Turns out it's a "pico fuse". See
