Topic: proper battery for sp-spsb-10

[rhinowing]

Hi all,
     Probably a dumb question, but...I recently got an SP-SPSB-10 box (and sound pros. mics) secondhand from a friend. There was a duracell MN21/23 12V battery in the box, which worked fine. I now need to buy more batteries, and can only find MN23 12V. I was just wondering if this will work ok to power the mics or if I need one which can vary between the two? Secondly, is there a rule of thumb for how long batteries tend to last in-box before they need to be changed?
thanks,

I just replaced the battery in mine, and the closest one I could fine here was an Energizer A23. Worked fine. I guess if it's the same size and voltage it will do the job. I'm kind of paranoid and get a new one for each show, which is probably overkill. But I did 2 shows this past week with the same battery, it would've been plugged in for around 6-7hrs total, no problems. I get fresh ones because I don't tape that often, so it could be months again before I use it.

I would either buy a 12V battery from Sound Pro (they sell for $3/each) or drop Chris (from SP) an email and ask him.  He is usually pretty good about replying to emails in a day or two.
