7.2 Maintenance of high voltage lithium batteries
DEEP BLUE batteries are basically protected against total discharge. As batteries are self-
discharging, a harmful total discharge risking to destroying the battery is nevertheless
possible.Sopleaserespectthefollowingadvice:
• Incasethehighvoltagebatteryshouldbemechanicallydamaged,
please do not use the DEEP BLUE system any more. Get in touch with
Torqeedo Service.
• HighvoltagecomponentsofDEEPBLUEsystemsarewatertight
(batteryIP67,chargerIP67,connectionboxIP66protected).
Howeveravoidingpermanentexposureofhighvoltagecomponents
to water is necessary.
• Alwayskeephighvoltagecomponents(batteries,connectionbox,
charger) of DEEP BLUE system clean and free from dirt.
•Chargethebatteryaftereachuse.Ideally,rechargethebatterydirectly
after use. In case of discharge down to less than 20 %, battery must be
recharged within 48 hours.
•Ifyouwanttostorethebatteryoveralongerperiod:Fullychargethe
battery before storing it. Check battery status once a month.
•Alwaysstorethebatteryatambienttemperaturesofbetween
-40°Cand+50°C(-40°Fand+122°F).
•Wedonotrecommendalongerstoragewithenabledcharger.Inthis
case, charger would start every 15 minutes. In case of an error mes-
sage, undesired total discharge may be the consequence.
