Which of the 3 (or more) are you referring to? There is the HV battery, 12V
battery, and key fob battery.

For the HV: Remove the cover and inspect the bus bars for corrosion
indicating terminal seal electrolyte leakage.  Also have a shop with the
proper scan tool log the min and max block voltages while under heavy drain
and heavy charge currents.  The bigger the difference between the 2 voltages
(delta V) the weaker the pack. See:

For the 12V: do a simple load test and check the electrolyte levels (acid).
the battery will either be AGM or flooded.  If there is no free liquid in
any of the cells it is AGM, if there is free liquid top it off with
distilled water.  Either way the case plastic is translucent so it should be
easy to tell.

For the FOB: just replace it, they are cheap. They are 3 for $ at the
Dollar Tree store near me.

    Lab tests on the current version of the pack indicate about 180k
miles under normal driving conditions. Older packs are prone to
corrosion at one or two terminals, but potential life may be equally good.

Have you had to replace the other battery? You know, the one that drives
the accessories? Mine (on my 2005 Prius) died after about 5 years.
