Optimate 0.8 Amp Lithium Battery Charger

Optimate 0.8 Amp Lithium Battery Charger

The OptiMate maintainer to protect your LiFePO4 battery in the most effective way.

  • Optimizes battery power and life
  • Saves low voltage LiFePO4 batteries
  • Specialized LiFePO4 maintenance
  • Protects LiFePO4 batteries

Product Description:

  • OptiMateTM lithium 0.8A, the OptiMate maintainer to protect your LiFePO4 battery in the most effective way.
  • The new OptiMate lithium 0.8A will protect your investment and guarantee your Lithium Iron Phosphate (LiFePO4 / LFP) battery will perform as advertised for a very long time.
  • OptiMate lithium 0.8A unique LiFePO4 specific program recharges and balances
  • cells within the battery efficiently and safely so it can be used with lithium batteries that do not have the built in balancing circuitry, the EarthX brand has this feature built in but if you have a different brand, this will balance the charge level of the cells.
  • OptiMate lithium 0.8A’s maintenance program delivers current to the vehicle
  • circuitry, protecting and keeping the battery at 100% charge.
  • OptiMate lithium 0.8A – Battery Performance Guaranteed!

How It Works:

  1. Pre-qualification / BMS reset: The charge program is selected according to battery voltage.

    For a battery with internal BMS (battery management system), which is the EarthX brand, which includes a low voltage cut-out; with OptiMate Lithium connected to the battery, disconnect the AC supply cord from AC power for 30 seconds and once again reconnect. The BMS reset program will attempt to reconnect the internal cells with the battery posts so that charging can commence.

  2. Low Volts Recovery: The OptiMate SAVE 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.

  3. Bulk Charge: Constant current of 800mA is delivered until the voltage has risen to 14.3V.

  4. 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.

  5. Absorption and Equalisation:  For up to 4 hours the current is delivered in pulses with voltage controlled between 14.0 and 14.3V, aiding cell voltage equalization and improving the battery’s overall power delivery.

  6. Voltage Retention Test: Conducted for up to 12 hours during which no charge current is delivered, with 3 possible test results indicating the battery’s general state of health or excessive self discharge or higher than expected power loss through the vehicle’s electrical system.

  7. Charge Maintenance: The 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 alternating charge and ‘rest’ maintenance program protects the battery against over discharge by connected vehicle circuitry, making it ideal for indefinite and 100% safe long term maintenance charging.
