With 800 milli-amps of charge current available OptiMate lithium unique multi step ampmatic™ program recharges and balances cells within the battery quickly and efficiently. This charger's maintenance program delivers current to the vehicle circuitry, protecting and keeping the battery at 100% charge.
How It Works
Pre-qualification Test / BMS Reset
Displays condition of the battery and measures environment temperature; charge program selected based on results. The BMS (Battery Management System) reset program will attempt to reconnect the internal cells with the battery posts so charging can begin.
Low Volts Recovery
Controlled charging in protection mode controls the charge of sensitive batteries to ensure that an over discharged battery will be correctly and safely recovered.
(Tests are conducted throughout this stage to determine if the battery has successfully recovered and can be advanced to BULK CHARGE.)
Processor actively adjusts charge current to match battery capacity and condition, achieving a complete charge in the shortest time.
Short-Circuited / Dead Cell Check
Charge progress is tracked against the ideal LiFePO4 charge curve. Internal damage will be detected at this point and unnecessary charging of the battery is prevented if it cannot be recovered.
Absorption & Equalization
For 10 minutes, current is delivered in controlled voltage pulses between 14.0 - 14.3V.
This improves the batteries cell equalization and overall power delivery.
Voltage Retention Test
30 minutes of testing is conducted while no charge is delivered to the battery.
The test results indicate 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.)
This stage is a 12 hour maintenance charge cycle consisting 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.
*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.*

PAID A GOOD PRICE FOR THE EARTHX BATTERY SO WHY NOT PRESERVE IT'S LIFE WITH THE CORRECT CHARGER. IT'S AN INVESTMENT.
I use this with my EarthX lithium battery. I was able to reset my battery after I left a switch on and discharged it to a point it cutoff and needed to be reset.
We bought this charger when we purchased a new EarthX Lithium Battery for our 2010 Harley-Davidson Classic Electra-Glide Ultra Motorcycle.
We mounted it on the wall of the garage where we park the bike. It works very well so far.
Nice looking too, as far as chargers go.
I felt it was expensive at almost $90.00, but so was the Lithium battery. If it lasts a long time it is worth the price.
