For long-term storage in an unused system – i.e. in a completely wired but deactivated state
– then the application should be cyclically commissioned (approximately every 4 months) in
order to avoid deep discharge of the lithium iron phosphate batteries that are installed. The
recharge interval can be extended to approximately 6 months if the fuse in the battery
module is removed. When stored at increased ambient temperatures, then the reduced
recharge intervals listed above must always be applied.
Note
For transport by air, it is legally stipulated that lithium iron phosphate batteries may only be
charged to a maximum of 30
% of their nominal capacity. This is the reason that when
supplied, the maximum energy content of the BAT8600
LiFePO4 battery module is 30 % of
the nominal capacity. As a consequence, we recommend that the BAT8600
LiFePO4 battery
module is fully charged after a long period of
standalone storage.
