ELI5: What is the difference between using multiple 1.5V batteries

A 9V battery is effectively 6 AAAA cells in a package, they''re really skinny batteries and can''t provide much current. A 9V only has a capacity of around 560 mAh compared to a standard AA battery at 2700 mAh so 6 AA batteries will last around 5x longer than a 9V under low load and significantly longer under higher loads.

How many hours will a 9vt battery typically last in an active bass?

I''ve got a couple of active basses. In general, the batteries should last for 6 to 12 months, depending on how much you play. If you leave your bass plugged in, the battery will probably be dead in 2 - 3 days max. My Yamaha TRBX604 came new out of the box, and the battery provided by the factory lasted about 7 months or so before it died.

5 Frequently Asked Questions about “Bass Energy Storage Two 9V Batteries”

Should I put a battery in my bass?

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.

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?

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. Moral of the story is always have at least one extra on hand at all times. The battery will never pick a good time to die.

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.

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.
