The following should clear away any haziness of the T-70 backup
battery change question as well as the LCD display.  It's straight out
of the T-70 manual, page 70.

Liquid Crystal Display
----------------------
The T70's display panel uses liquid crystal to indicate exposure
information.  After about 5 years of normal use, the display may
become hard to read.

Back-up battery
---------------
The T70 has a built-in back-up battery which memorizes the display
panel data, such as the frame counter number and the ISO film speed,
when the AA size batteries are taken out for replacement.  Battery
life is about 5 years.  When voltage becomes insufficient, "ISO 100"
will blink (at 2 Hz) on the display panel after loading batteries for
normal camera operations.  If the back-up battery is removed, the
memory will be erased.  In this case, reset the film speed.

Take your camera to the nearest Canon Service facility for the
replacement of the liquid crystal or the back-up battery.

-----------

The main batteries will last for 20 (NiCad) to 40 (Alkaline)
36-exposure rolls in normal temperatures, so you can be assured that
you can take this many shots before worrying about battery failure.
And even if the battery fails, you're OK as long as you change your
main (AA) batteries at the end of a roll and reset the film speed
after changing them.

In any case, I'm replacing my backup battery and LCD after four years,
just to be on the safe side...
