Lithium Charger Main Description
Our Optimate lithium charger developed with Super B. 5A and battery conditioning mode to extends the battery life.
OptiMate lithium, the first OptiMate to protect your LiFePO4 battery in a way no other charger did before!
The new OptiMate lithium will protect your investment and guarantee your Lithium Iron Phosphate (LiFePO4 / LFP) battery will perform as advertised for a very long time.
With 5 Amps of charge current available OptiMate lithium unique multi step ampmatic program recharges and balances cells within the battery quickly and efficiently.
OptiMate lithium’s maintenance program delivers current to the vehicle circuitry, protecting and keeping the battery at 100% charge.
OptiMate lithium – Battery Performance Guaranteed!
How Does This Battery Charger Work?
OptiMate Lithium displays the condition of
the battery before charging and measures environment temperature.
The ampmatic charge program is selected according to
temperature and battery condition.
Low Volts recovery:
The safeTo protection mode controls charging during this sensitive battery SAVE stage, to ensure that an over discharged battery will be correctly and safely recovered.
Tests are conducted through-out the SAVE program to determine if the battery has successfully recovered and can advance to BULK CHARGE.
The ampmatic processor actively adjusts charge
current to match battery capacity and condition, achieving a complete charge in the shortest time. Progress is tracked against the ideal
charge curve for LiFePO4 batteries.
Short-circuited / dead cell check:
Charge progress is tracked against the ideal LiFePO4 charge curve, internal damage will be
detected and unnecessary charging is prevented of a battery that cannot be recovered.
Absorption and equalisation:
For 10 minutes the current is delivered in pulses with voltage controlled between 14,0 and 14,3V,
aiding cell voltage equalisation and improving the battery’s overall power delivery.
The voltage is limited at 13,6V while the ampmatic processor monitors the current absorbed by the battery.
If this reveals a less than optimal charge, the program reverts to absorption for a further 10 minutes.
Voltage retention test:
Is conducted for 30 minutes during which no charge current is delivered, with 5 possible test results indicating the battery’s general state of health.
A green (voltage > 12,7V) result extends the test up to 12 hours, to check for excessive self discharge or higher than expected power loss through the
vehicle’s electrical system.
The 12 hour MAINTENANCE CHARGE CYCLE consists of 30 minute float charge periods at a voltage of 13,6V followed by and alternating with a 30 minute ‘rest’ (no charge current) periods.
During the float charge period current is delivered only if the battery has lost charge due to connected vehicle circuitry.
A refresh cycle may be performed if the charge level has dropped significantly.
The voltage retention test and maintenance charge cycle will repeat
24 hours after the start of the very first test and continue to repeat for as long as the charger remains connected.
The alternating charge and ‘rest’ maintenance program protects the battery against over discharge by connected vehicle circuitry. This makes it ideal for indefinite and 100% safe long term maintenance charging.
