With 5 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
Displays condition of the battery and measures environment temperature; charge program selected based on results.
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.
If battery has capped at 13.6V after the 10 minute Absorption and equalization period and reveals a less than optimal charge, the program reverts to absorption for an additional 10 minutes.
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.*

When swapping out my Odyssey 680s for EarthX 680s, my initial due diligence included careful research about proper charging. I had hopes of continuing to use the 10 year old
Enersys charger with my LiFePO batteries. Detailed conversations with both the charger folks and the battery folks confirmed that this would be possible...thus allowing me to retain the on-board charging and battery monitoring set up I had in place. Nonetheless, in short order, I found myself with a disconcerting array of red and amber lights as well as a brand new LiFePO battery reading just over 9 volts and a charger unwilling to do its job. All issues were promptly solved by pulling out the old charger and replacing it with the Optimate 5 Amp unit which plays very nicely with those Earthx batteries...quick delivery
Good charger after about 1 month of use. Lots of indicators for the various states of charging. My new LiFePO4 battery seems to love it.
