Members mbengs1 Posted December 29, 2013 Members Share Posted December 29, 2013 I tried a new 9v eveready battery for the first time in my boss ST-2 power stack and its been only at most 2 hours and the led is not as bright anymore. but it still sounds like new, just the led is a bit dimmer. i usually use a 1 spot with a multi-plug to power my pedals but i just wanted to try a battery this time. i wonder if my pedals are broken since they eat batterylife kinda fast.

Members Player99 Posted December 29, 2013 Members Share Posted December 29, 2013 Check the mA requirements of the pedals. A dirt box or a compressor might be low (3mA - 20mA) but a digital pedal can be 300mA or 400mA. Some are even 1700mA. Also leaving the cable in the input side drains the battery even if the pedal is off. Link to comment Share on other sites More sharing options...
Phil O'Keefe Posted December 29, 2013 Share Posted December 29, 2013 Yup... it entirely depends on which Boss pedal, and which type of 9V battery. In the case of the ST-2: Current Draw 36 mA (DC 9 V)Expected battery life under continuous use:Carbon: 3 hours Alkaline: 10 hours These figures will vary depending on the actual conditions of use. Tha's according to the info posted on the Boss site. http://www.bossus.com/gear/productdetails.php?ProductId=1130 And Player99 is absolutely correct - you should always unplug the cable from the pedal's input whenever you're not using it. Doing so disconnects the battery from the circuit - essentially turning it off. If you don't unplug, you'll wear the battery out a lot faster than if you do.

Members Mr.scary96 Posted December 30, 2013 Members Share Posted December 30, 2013 Really depends on which Boss pedal. Like my PS-6 eats my 9 volts more than my Boss PH-2 Link to comment Share on other sites More sharing options...
Members Bobby1Note Posted January 2, 2014 Members Share Posted January 2, 2014 Another point,,,, don't assume that "new" batteries will be fully charged, even when they're fresh out of the package.I recently found what I thought was a "great deal" on supposedly brand-new alkaline batteries, at a local electrical-supply place. Well, I'd put one of those in a device, and the battery-life was very short lived. After several batteries had produced similar results, I decided to put the "new" batteries on a tester. Those batteries were right on the margin,,,, almost dead, but not quite. Package after package yielded the same results. So much for "a good deal".I decided to go to Costco, and try their alkaline batteries. I put those on the tester, and voila,,,, fully charged. I now buy my batteries from vendors who continuously move stock, and replenish frequently.Battery testers are cheap. I'd highly recommend you get one. You might be shocked to see how bad "new" batteries can be,,, even top brand-names. Link to comment Share on other sites More sharing options...
