The flashing light is just an indicator for the electrolyte level within the battery, way back in the days that you added water to keep the level up.
With the newer, sealed and maintenance free batteries, this is obsolete. It should not affect the running of the machine in any way, just kind of annoying.
One way to bypass it is to plug in a resistor, which is basically what that unit is. I can't remember the ohm rating that works, but Google it and I am sure you will find something.

To the gentleman with the battery sensor problem. I drilled one of the fill holes a little bigger, enough to accommodate the sensor, and placed duct tape over it. Works perfect.
