So, I don't see how CA is able to draw enough current from the Braille battery over a couple of days or so to cause problems...
Take note that the Braille battery is about 1/3 the size of the stock battery, therefore less reserve capacity. Although the small amount of draw is insignificant for the stock battery, it may cause an issue with the low reserve capacity of the Braille.
