MixPre -- stuck battery -- ??
« on: April 27, 2008, 02:28:15 PM »
Help. Has anyone ever had a battery stick in the compartment of a MixPre (or similar model)? The battery slides around in there, but gets hung up about a half inch from the threads -- looks like the battery compartment is just every so slightly narrower there. It appears that the battery label is what's doing the hanging. Hmmm....I've tried everything I can think of, and it just doesn't seem to want to come thru that part. I don't remember the battery being tight when I installed it last night.  ::)   I've tried gluing a dowel to the batt and pulling on it, but haven't had much luck so far.

Has anyone ever encountered this before? Any suggestions?   ???

You try using one of these? ;D





I think someone here had the same problem not long ago, not sure how they resolved it.

Thanks for the link! I thought I remembered seeing something here before, but I didn't have any luck searching.

I was afraid to smack it around too much, but based on the recommendations in the other thread I really layed into it. (Sorta like that Prodigy song, except I can only hope that it didn't "change my pitch up"  >:D) Took quite a bit of violent coaxing and swearing to get the damned thing out of there.

Thanks for the help!!

Don't forget to email Sound Devices about this, it's a design flaw.

It happened to me, and three other people including you now on these forums.

Have you tried using quality brand of batteries? Never happened to me. IMHO not a design flaw.

Duracell and Energizer not quality brands?

There is a lip on the inside of the battery tube caused by a narrowing of the tube about 2 cm down from the entrance. If a battery label starts to come off, the battery is slightly fat or damaged (particularly on the end where the cover wraps over the terminal) it can become caught on the lip where it narrows. It most definitely is a design flaw. It's not entirely clear to me what the purpose of the narrowing is, even if they -

1. Enlarged the tube diameter at the end by 1 mm
2. Kept the same diameter all the way down.
3. Changed the angle of the narrowing step (which seems to be about 45 degrees), they would avoid these issues.

BTW: it has only happened to me once too. But once may be a disaster in the field when you are trying to change batteries on an important gig.

My problem was exactly as digifish described (very slight taper about 2 cm in caused the batts to get stuck). I've been lucky since by avoiding use of the brand of batteries that I had the problem with. I use all rechargables: the stuck ones were Lenmar brand, the ones that have been behaving OK are Sanyos.

You won't regret it. The MixPre is a stunning piece of kit, particularly where low-noise is concerned.

have the same problem with my new mixpre-D. The sound devices didn't solve this problem. It's stupid how 800$ machine can stuck with a problem like this. I have a bruise on my hand trying to get the battery out. Maybe try to drill the battery into pieces? But it's not safe. I'm really dissapointed ???

I don't want to drill, it's likely insane, but this just because of my big confusion. :(
maybe just use screwdriver with a little screw into a battery and then catch the battery fast?
