Battery Indicator doesn't match display?
 

I noticed today the indicator lights on my battery show one extra bar than what is shown on the display (battery shows 4 bars, display shows 3 bars). It's a shimano setup. Is this norm? Do I need to do something to regulate the battery with the screen? Which is generally more accurate?

I haven't pressed the display on my batteries (I have several) in years. They didn't tell me much when new, three greenish LED's and one red LED. The display is a better indicator, in my opinion, but if yours only has three bars, that's really basic. I guess you want to be near home when you're down to one bar.

Of course my display has more than three bars on it.

But nevermind it seems to have corrected itself during a long ride last night and they both match.
