Hey there, I have a mouse that currently uses a Li-ion battery pack, and requires a charging dock.

I decided that the charging dock is too big to lug around, so I want to swap out the Li-ion for a battery holder that holds normal batteries.

Provided that I can get around the same voltage and same current from the batteries, would this replacement work safely?

Also, Li-ion battery packs have 3 wires -- I assume one's positive, one's negative, one's ground.

However, typical battery holders only have 2 wires: positive and negative.

How would I go about adding the 3rd wire? Or would I have to worry about it at all?

Thanks.

 

Hello,

It can be that a thermo sensing element is connected to the third terminal.
Take a look at the battery university for more info.

There are more link on batteries over here.

In that case, it is most likely a battery gauge, since the mouse has a battery indicator.
However, that is not my main concern yet. I'm wondering if swapping the Li-ion out for a battery holder (to use normal batteries) is possible?

 

Hello,

When carging a litium ion battery the temperature has to be monitored.
If the temperature gets to high the lithium ion battery may even explode.

On this page there are some links for lithium ion and lithium polymer batteries.
