clips, and the System Controller, refer to
Wearing and Carrying System Components on page

Removing Batteries from Service
One pair of new HeartMate 14 Volt Lithium-Ion batteries provides up to 17 hours of support
under nominal operating conditions (pump flows of 5.4 lpm). Refer to
Cleaning and
Maintenance on page 8-4 for information on cleaning and maintaining HeartMate 14 Volt
Lithium-Ion batteries and battery clips.
HeartMate 14 Volt Lithium-Ion batteries last for less time if the patient is active or emotionally
stressed. As batteries get older, they power the system for shorter periods of time. If a pair of
HeartMate batteries does not give at least four hours of support, take both batteries out of
service.
A new battery that is stored and used according to the acceptable environmental conditions
should be usable for approximately 360 cycles or 36 months from the date of manufacturer,
whichever comes first. After this time, battery performance cannot be guaranteed. Call Thoratec
Corporation for a replacement when either of these milestones is reached. Refer to
Storage and
Transport on page 8-3.
The white battery label on each battery contains several safety symbols and the battery's
expiration date. The battery may need to be replaced earlier than the expiration date,
depending on usage. Batteries should not be used after their expiration date. Dispose of expired
batteries according to local, state, and federal regulations. Refer to
Product Disposal on page
8-8 for information on disposing of HeartMate batteries.
Caring for Batteries and Battery Clips
HeartMate batteries require periodic inspection and cleaning for the most reliable performance.
Refer to
Cleaning HeartMate 14 Volt Lithium-Ion Batteries and Battery Clips on page 8-6 for
detailed information on inspecting and cleaning batteries and battery clips.
