    hey whats up guys and gals

    Heres the deal. I have a spector 4 string with the 9 volt electronics. Its a p neck and jazz bridge setup. I'm not sure how old the bass is but i dont think the battery has ever been changed. I bought it used. The battery in the bass looks like a battery from an orignal instrument. Ive had the bass for about a year now, how long are these batteries supposed to last? Thanks.

    You should change it.

    Here's the method to calculate battery life:

    Get a Multimeter, a digital one is preferable.

    Disconnect one battery pole from the plug and put the multimeter (set it on 20mA DC) between those two.

    Plug a cable into the bass and check the reading.

    A 9V alkaline usually has around 550 mAh

    550 mAh divided by the reading on your multimeter gives you the approximate battery life in hours.

    Of course: Always unplug your bass when you don't play your bass, because the plug activates the circuit and drains the battery.

    Just as front line maintenance i change the 9 volt battery every 3 to 6 months then give it to my brother to use in his effect pedals.
