i2 Odd battery issue?

[dmurphy]

Hi all.... Having a strange battery issue on my i2 SE.

It's been plugged in and charging just fine for the last several months in my garage (it's winter.)

All of a sudden this week, instead of the normal quick-blink green lights, I'm getting two red battery lights. This may (or may not) have started after a power outage last week.

Long story short - I disconnect the charger, try to power up the Segway, and it begins starting up, but starts flashing all 5 of the red balance lights and beeping at me -- exactly the same behavior as if I try to power it up while plugged in.

I haven't had a chance to drop the batteries and reinstall them yet - will do so when I get back home from my work trip - but has anyone seen this behavior before?

Wonder if it has to do with the relative cold in the garage, or possibly a high-voltage spike during the power outage?

It seems as if the Segway thinks it's plugged in when it isn't ...
