Notes on Battery Packs

Battery Pack life will vary depending on handset model, features, and system
infrastructure.
Maximum Battery Pack performance is achieved after a few charge/discharge
cycles.
If multiple Battery Packs are supplied with your handset, Avaya recommends
that each be fully charged upon receipt to prolong battery life. Battery Packs
will slowly lose charge if unused. To maintain battery potential, charge the
unused Battery Packs occasionally or alternate Battery Pack use.
After a length of time Battery Packs will lose the ability to maintain a charge
and to perform at maximum capacity and will need to be replaced. This is
normal for all batteries.
If your Battery Pack requires replacement, contact your system administrator.
Overnight charging is best done while the handset is turned off.
If the handset does not charge, clean Battery Pack, charger and handset
contacts with an alcohol swab.
When the handset is properly seated, the backlight comes on briefly and the
handset beeps to indicate that charging has begun.
Any battery which exhibits swelling, cracking or other abnormality should be
disposed of promptly and properly.
Note:
Only use Avaya 3641/3645 Battery Packs with Avaya 3641/3645 IP Wireless Handsets.
