I have a Sentry S3877 safe. The battery case has crumbled

Customer Question

I have a Sentry S3877 safe. The battery case has crumbled and I need a replacement. Is it possible to replace it? It connects like a 9 volt battery, but it is a plastic case that holds four (4) AA batteries. Thanks, ***** *****

Hi Landis,

Im sorry to hear that the battery box became damaged.

Yes you can replace that box. They sell this part but Sentry safe does not sell it.

You can however find a similar one for this application from many sites, but Radio Shack carries these if you have one near you still.

But you can also find one here at this excellent surplus shop online. I use then all the time with great results.

Also when you have the battery box you need, you can re connect with me for advice on swapping these out. No additional cost ;-)

Please visit this site:

I would call them to get the correct one fastest;-)


In any case, I will stick with you until this is complete.
