6. Battery Use, Maintenance and Storage
CAUTION
Do not store batteries for more than three months without subjecting them to normal discharge and recharge
cycling. Ideally, batteries not being used routinely on a less than monthly frequency should be charge-cycled
every three months, minimum.
Optimal storage for Lithium Ion batteries is at 50% charge and approximately 0ºC-10ºC.
CAUTION
MAXAIR Systems Lithium Ion (Li-Ion) batteries (LIBs) are secondary (rechargeable) batteries, not primary
(storage) batteries.
MAXAIR Systems Li-Ion Batteries (LIBs) hold much of their charge for a year or longer. However, as with all
rechargeable batteries, the amount of charge will decline slowly in use or storage
(self
-
discharge rate)
,
depending on time and temperature, and the maximum
recoverable charge
level diminishes gradually over the
life of the battery.
6.1 Routine Infection Control use in med/surg and ED areas
•
If LIBs are being used more than once per month, they should be connected to chargers in between uses.
•
Before each use, physically inspect the LIB. If you perceive physical damage or tampering,use a different MAXAIR LIB and
replace the damaged LIB as soon as possible.
•
Routinely, every 3-6 months, perform the “LIB Check Procedure” (see Section 28.3.7). If this procedure results in a “Suspect
LIB”, use a different MAXAIR LIB and replace the Suspect LIB as soon as possible.
•
Check LIBs that are connected to MAXAIR chargers on a daily basis. If the charger LED is green, the LIB is ready for use
and should be disconnected from the charger.
6.2 Emergency Preparedness (EP) and In-Frequent Use
•
MAXAIR batteries are shipped to customers at the 50% charge level (approximately 14.6v output level). This is the
approximate level recommended for long term storage of a Li-Ion batteries, and therefore what we recommend for EP use
to achieve the longest overall useful life of the batteries.
o
For a new 2500-30TSC battery this represents up to 8 hours of use before recharging to a fully charged level.
o
For a new 2500-37TSC battery this represents up to 6 hours of use before recharging to a fully charged level.
o
For a new 2500-36TSC battery this represents up to 4 hours of use before recharging to a fully charged level
•
For systems that may be in storage and not used for longer than a year, the battery charge should be revalidated every
3-6 months, minimum.
CAUTION
Check LIBs connected to chargers on a daily basis.
If a LIB is warm-to-hot to the touch, disconnect the LIB from the charger and replace it immediately.If this condition
is ever observed, please mark the specific battery and the specific charger it was connected to when the
heating was noted, and contact us for replacement. Call Customer Service, 1-800-443-3842, for return and
replacement instructions.
If the charger LED is Green, the LIB is fully charged and ready for use, therefore disconnect if from the charger.
DO NOT leave the LIBs on the chargers after the charger LED turns Green.
