Charging Your OzCharge® Lithium Battery
Lithium batteries need to be charged slightly differently to other batteries to ensure they live a long life
and provide maximum capacity. There are several charging devices you can utilise, but whichever
device you choose, it must have a lithium charge profile.
We recommended that you use a charger that can deliver a charge current or amperage of 20% to
30%
or less of your battery capacity. You can charge at much higher rates (refer to the product label
on the battery) however you will reduce the cycle life of your battery at higher charge currents.
Check the “Maximum Charge Voltage” on your products Data Sheet and ensure the maximum output
voltage of any charging device connected to the battery does not exceed that voltage.
Charge Method
Important Note
A/C Domestic Battery Charger
Ensure your charger has a dedicated Lithium setting.
Vehicle Alternator D/C
Never directly charge from an alternator without an
appropriate regulator or DCtoDC charger in place
between the alternator and the Lithium battery. Not
recommended for under bonnet installations.
DCtoDC charger
Ensure your DCtoDC charger has a Lithium charge
setting.
Solar D/C
Never directly connect an unregulated solar panel to the
battery or you may exceed the maximum voltage allowed
and damage may occur. Use a solar regulator between
the panel and the battery.
Solar Regulator D/C
Ensure your solar regulator has a dedicated Lithium
charge setting.
A/C Mains Power
NEVER connect your battery directly to A/C Mains power.
Always use a dedicated charger
WARNING Do not use a charge profile with an Equalisation setting. This may damage the battery and
void the warranty.
