However, to make batteries last, there is no need to remove them, just make sure to unplug the bass between practices. That should extend battery lifetime.
Of course, you could have gotten a battery that was in the bass longer, or played a lot at the store before you took it home, IDK, anything is possible with the battery that come with the bass, but if you put one in, it should not bother you for a while.
Do I need to unplug my bass?
Yes, you must unplug the bass, that is the cord from the bass itself, not just the amp. When you insert the jack, that is the “ON” switch for your active bass, it will drain battery up until you remove the cord, or it drains. I have a bass I play every day, it has the battery that came with the bass, and its been about 3 months and it is fine.
Does active/passive switch prevent battery drain while plugged in a bass?
If a bass has an active/passive switch it is guaranteed to have passive pickups (active/passive switches do not work with active pickups). With an active/passive switch, it may or may not prevent battery drain while the bass is plugged in. It depends on the bass. Hmm. I did not know that about bass pick ups.

How long does a battery last if plugged in?
The cable still being plugged in was your big problem for sure, but always remember that not all batteries even of the same type/brand won't last the same. Depending on how long they have been sitting on the shelf, storage temp and factors like that, you might get 4 months from one and 6 from the next.
