Operation manual
• An automatic cut out charger must be used, otherwise irreparable
damage will occur and your warranty voided.
• Disconnect your fridge and DC charging lead from the battery.
• Before turning the battery charger on, connect the alligator clamps to the + and
- posts at the top of the CoolPower44, ensuring good contact. Now turn the
charger on.
• Charging times will vary depending on depth of battery discharge prior to
charging and the battery charger used.
• To test your battery after charging, disconnect the charger, wait 30 minutes and
then follow the procedure outlined in Testing (page 5).
Depth of discharge v's battery life
• The depth of discharge (DOD) is the amount the battery is drained without charging.
For example, a remaining capacity of 20% equates to an 80% DOD.
• The service life is the number of times the battery will cycle from fully charged to a
given DOD. For a battery in continuous cycle service use, approximate service life
figures are as follows:
DOD
80 %
50 %
30 %
• Total battery life is a combination of service life and storage conditions when not in
use and is influenced by other variables. However as a general guideline you can
increase the life of your battery by not discharging any further than necessary before
charging.
Storage
All batteries benefit from periodic charging when not in use. Following this advice will
ensure optimum life from your CoolPower44. Self-discharge characteristics vary with
ambient temperature and age, but as a general guideline the battery should be fully
charged every 3-4 months.
