Product Description

Free Standard Shipping!

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

  1. 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.
  2. 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.)
  3. Bulk Charge
    Processor actively adjusts charge current to match battery capacity and condition, achieving a complete charge in the shortest time.
  4. 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.
  5. 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.
  6. 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.)
  7. Charge Maintenance
    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.*

Battery Charger/Trickle

For a reason we have not been able to find ... the battery was draining down. I wanted to a trickle charger to keep the battery (EarthX) at full charge. I have been using for about 3 weeks and it is working great!

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.

Good charger!

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.
