Check that this number is printed on your processor.<\/p>\n<ul>\n<li>Remove the battery and look at the processor body for a code starting with CP.<\/li>\n<li>Write the code down before you order. Nucleus 8 (CP1110) batteries and parts are a different design, so do not mix them.<\/li>\n<li>Not sure?

A <a href=\"\/shop\/hearing-aid-dryer\/\">hearing aid dryer<\/a> makes this easy.<\/li>\n<li>Store it in its case, away from heat, direct sun and small children or pets.<\/li>\n<li>Check the cable and microphone covers once a week for cracks, dirt or loose plugs.<\/li>\n<li>Keep a small spare kit: a charged battery, a spare cable and a pack of covers.<\/li>\n<\/ul>\n<h2 id=\"battery-care-and-charging\">Battery care and charging<\/h2>\n<p>Rechargeable batteries are the Nucleus 7 part that ages fastest, because every charge cycle wears them a little. To get the most from them:<\/p>\n<ul>\n<li>Charge them fully before first use and use a <a href=\"\/shop\/cochlear-nucleus-7-charger\/\">Nucleus 7 charger<\/a>.<\/li>\n<li>Rotate two batteries so each one is used and charged evenly.<\/li>\n<li>Do not leave batteries in a hot car or on a sunny window sill.<\/li>\n<li>If you will not use a spare for a few weeks, store it partly charged.<\/li>\n<li>Replace a battery when it no longer lasts your normal day.

Changing it takes about a minute:<\/p>\n<ol>\n<li>Take off the processor and gently unplug the old cable from the coil and the processor. Pull the plug, never the wire.<\/li>\n<li>Choose a new <a href=\"\/shop\/cochlear-nucleus-7-slimline-coil-with-cable\/\">Nucleus 7 cable<\/a> of the same length as the old one.<\/li>\n<li>Push the new cable firmly into the coil, then into the processor.<\/li>\n<li>Put the processor on and move your head gently.
