Average lifespan of V9 battery?

    Hey guys,
    I'm grabbing a Squier Deluxe V Active bass and I've heard it uses a V9 battery (and that it stops working in passive mode as well if the battery dies).

    I know it may depend on the battery itself but what is the average lifespan of the V9 battery? Does it get depleted fast? Should I always have 2-3 backup batteries?

    I have 2 active basses a Tobias and a MusicMan. I use both of them gigging and playing them almost everyday, and a battery seems to last forever, I change them once a year just to be sure. If I measure the voltage after a year It still says 8,9 volt, so don't worry, just change the batteries once in a while and remember to unplug the bass when not in use.

    Ah, sound great then! I was just worried of my bass battery dying in the most responsible moment :x but I shouldn't be worried about that then!

    What's a V9 battery??

    If you meant 9V battery........in my experience......under pretty active playing conditions, 4-6 months. Under sporadic playing.......up to a year. I change mine every 4 months. That's 3 batteries a year which is pretty inexpensive.

    I read something about unplugging the cord even if it's the amp is turned off. I don't really get the point if the amp is already turned off. How does it affect anything?

    The switch for the active electronics is in the socket for the chord so if the amp is on or not your using the battery if you have a chord plugged in

    I tend to change out my battery before a gig and recycle it into my wireless system so on average I am changing my battery in my bass often for the best tone and I use rayovac batteries

    I don't play active basses but this is good advice. I once left a Boss pedal plugged in long enough to drain the battery (I wasn't using it very frequently at the time)

    The input jack has a third contact that works as a mechanical switch. It connects and disconnects the power from the battery. If you leave a cable plugged in to the input of your bass your battery will last only a day or two.
  9. It seems to last over a year with frequent use with a set of EMG's. I change it out after a year and it still has a full charge.

    I get about 4 months if I am playing it quite a bit.

    A v9 battery is the battery in a Motorola cellphone (The Razr, to be exact) ;)

    A 9v's life span is dependent upon how much you use it through an amp (via, 1/4" cable) and that it is wired properly (to a "stereo" jack, to switch it on and off, with the 1/4").

    for some estimates, a year, for others, might be 6 months......YMMV.

    None of my basses runs on batteries. I'm currently without even a single pedal, so things are pretty simple these days. I sound pretty good, too! :D (just playing with you ;) )

    Full Charge? Unlikely! Unless you never played it in that years time and even then.....

    I'd be afraid the battery would start to leak after a year!

    Just remember to keep it unplugged when it's not in use.. Didn't know about that when I got my first active, I was getting kinda irate at how fast I was burning through batteries. :rolleyes:

    This may sound like a stupid question, but do active basses require any special cord to connect it to the amp?

    This is the key to a long-lasting battery.. :)

    I replace mine when I replace my smoke detector batteries (when we shift to and from Daylight Saving Time)

    A standard 1/4" cord works fine. Some bass amps have dual inputs, low and high impedance, for passive and active inputs, respectively. Most Ashdown amps, for example.

    It is the OUTPUT jack of the bass that has the switch for the power. INPUT is on the amp. Unplug it when you are done playing and the battery can last a year. If it is more than 3-4 months old, change it before a major gig, or test it with a proper battery tester that puts a load on the battery (NOT a voltmeter).

    A few years back, when I bought my Ritter Roya, I found some "power bug" batteries in the compartments. They're lithium 9V's & can last 2 to 5 times longer than alkaline (depending who you ask). Power bugs are no longer available, but they were made by Ultralife, which I use currently.

    Google for more info.
