Do not try to recharge a battery not intended to be recharged - it can overheat and rupture. (Follow battery manufacturer’s directions.)
inserting the batteries
Two 'AAA' size batteries (sold separately) should be used to backup
the clock and keep up alarm settings in memory in the event the
AC adaptor is disconnected or there is a power failure.
Open the battery door
Insert two “AAA” batteries as shown. (Alkaline batteries are
recommended for the longest backup time.)
Close the battery door

To avoid the current time and alarm setting being erased or reset,
do not disconnect the AC power adaptor when replacing the batteries
