What to expect from your batteries
Which battery to use (type 13, 675 or 9V) will depend on which Baha sound processor you are using. Just
remember that for the smaller type 13 and 675 batteries, the battery will begin to drain once you remove
the plastic strip – even if the sound processor is not actually in use! The batteries delivered with your
sound processor reflect Cochlear’s latest battery brand recommendation.
There are a number of factors that affect battery life. Brand type is one factor; low temperatures and
hourly use are others. The programme and volume control settings – as well as the use of accessories such
as FM equipment – can also affect the life of the battery. Be sure to use only new, high quality batteries
as this gives the best sound performance.
Testing type 13 and 675 batteries
To test the battery, place it in the tester (provided in your Aftercare Kit)
with the plus-mark facing upwards, and press it onto the metal band. The
display screen will then indicate how much power is left. The more bars
there are, the more power is left in the battery.
