The batteries on my battery module (that power my binaural microphones) died.

I went to Wal-Mart to get some new ones.

They're the small, flat, round ones. They are 3, 3volt lithium batteries (9 volts total).

So I went to Wal-Mart and got some more.

Come to find out, the numbers are different. The ones that came with the battery module are: CR2016. I bought CR2032. But they are still 3 volt lithiums.

If I use these will it mess up anything?

My friend's coming over tonight and I can't go back to Wal-Mart so I wanna know if I use these if it will fuck anything up.

Thanks.
 
CR 2016 is 75 mAh capacity. CR 2032 is 180 mAh capacity. Same in all other respects. CR 2032 will probably last longer in use.

Thanks. I'm a little worried though because if I mess something up then I won't be able to replace it.

This is what Wiki says:

CR2016: Standard Discharge Current: 0.1 mA. Often used in pairs instead of CR2032 for devices that require more than 3 volts, like blue/white LED flashlights. CAUTION: Using 2 CR2016 when not specified can damage a device.

CR2032: Standard Discharge Current: 0.2 mA. Maximum discharge current: 3 mA. Maximum pulse discharge current: 15 mA. Common battery in computers to keep the date and CMOS settings current when power is off.

Although the manual for the battery module just says "Uses standard 3 volt lithium batteries that can be found anywhere"

They don't state specifically CR2016, or CR2032. But the ones I took out of there are 2016.

Should be fine. About the only thing that varies among lithium cells is capacity, diameter, and thickness (and only slightly on those last two). If the new battery isn't too big, it should work fine.

(Well, technically, there are a few reverse-polarity lithium cells, IIRC, so you should watch out for those, but that should be easy to spot. Make sure the plus is on the same side. :D)
 
The Wiki caution appears to apply to putting two 3volt CR batteries in series which of course would give you 6 volts and in a device designed for only 3 volts would not be a smart move...

Yea I was going to try it but I didn't notice they were bigger until I took them out of the package. So they probably wouldn't fit well anyway. I'll just have to pick up the right ones today.

Thanks.
