XDA member FRANQ_23_PL wrote a guide to enable notifications for low battery and also a way to change the sound of notification on Windows Mobile devices.
As you will have to import the registry settings provided by the developer, Resco Registry Editor or a similar program is required to do this. A registry hack is also provided to unlock all notification methods.
Be sure to back up your registry before proceeding.
This guide was meant for the HTC Leo but should work on other devices as well.

[MOD] Enable hidden “battery low” in notification list + custom sound [update 25-JUN]
I found this yesterday when i was pissed off, that i don’t hear sound notification,
that my battery is low and my phone turn off outside when i need it working.
My first “discovery” (maybe everyone know that, for me this is new) is that in \Windows\
is sound file lowbatt.wav and this file is sound of low battery notification, so we can replace in by any sound we want.
I lookin for registry assocation of this file and then i found how to enable “Low battery” possition
in Settings>Sounds and notifications>tab “Notifications”>first drop-down list.
To enable this option please import REG file from attachments. It casuse in this drop-down list appear “Battery low” option.
If you want to have this possition in your language, there is source code and you can modify “Battery low” from las line,
copy this whole code, paste to PC Notepad and save as “*.*” and file name *.REG and in next step send it to phone
and import to registry with Resco Registry:
You can find more information in the registry hack’s thread.___________________
