Batteries - the "What to Know" - The LVAD word

 What to Know about your Batteries:

1. Only use Thoratec's PBU to charge HeartMate batteries. Other battery chargers may
2. damage the batteries.
3. * Do not use batteries below 150 F (-10o C) or above 1050 F (40'C) or they may fail
4. suddenly. If batteries are below room temperature (68-720 F, 20-230C) during use, their capacity will be reduced. At the low end of the temperature range (I150 F, -10WC), run time will be reduced by 50%.
5. The batteries should be routinely replaced, approximately every six months, or if operating time is reduced to two hours.

To prevent deterioration or damage to batteries:

1. Do not drop or subject batteries to strong physical shock. Dropped batteries should be replaced.
2. Do not leave or store batteries in hot or cold areas (car trunks, etc.) or battery life will be shortened.
3. Do not directly connect the negative and positive battery terminals.
4. Do not use expired or defective batteries. Use of expired or defective batteries may result in reduced operating time or abrupt loss of LVAD function.
5. Recharge used batteries within 12 hours or battery life will be shortened.
6. Use of expired or defective batteries may result in reduced operating time or abrupt loss of LVAD function.
