Can't update Asus Live Updated due to battery

I can't update using the updater. I now have listed a critical update of the Asus Sonic Suite Plugins 2.4.16. When i try it tells me that the battery has to be fully charged.
I'm plugged in but the battery no longer has a charge, I'd have to buy a new one it looks like to install the updates.
Is there a manual way to do the updates?
