[Biturbos4] Battery Life

[Steven Lin]

Before you change your battery, double-check the water level in the
battery.  I managed to eke out another year or so of life of it before
it finally gave up.  Make sure to use only distilled water!

I replaced it with some kind of Sears Die Hard International.  Fits
fine, without any adjustment.  If you search on Audiworld, you'll find
references to a few other brands.
