It doesn't do that "all the time", it only does it when the battery is detected as low... I don't think this a useful feature to have, just as we don't have a setting to _not_ warn when a laptop's battery is low.

Or just change the batteries?

The basic problem is that "Low Battery" is set at 20% and, in my case, 20% of battery means that remains one or two months of use.

IMHO cannot put the mouse or keyboard low battery warning at same level of laptop low battery warning.

Is that because you don't use them often, or because those devices' batteries last ages? What devices are they?

I'd be fine lowering the warning level for that, certainly.

I think that the devices don't report battery levels accurate and drops too fast to low levels.

There is a Logitech Performance MX mouse and Logitech K800 keyboard.

Yes, what do you think about add in Energy settings a slider like "Warn me at % of remaining battery"?

I've changed the defaults in UPower:

I will not add a setting for that, that's not how we roll. Resolving as WONTFIX as the original request won't be met.
