OptiMate Lithium 5.0A Lithium battery maintainer

Protects your Lithium Iron battery ensuring your battery will perform as advertised for as long as possible. The unique eight stage Lithium-specific program recovers and protects discharged batteries recharges and balances the cells within the battery efficiently and safely then keeps the battery at 100% charge and ready to use at all times.

How It works

  • 1. Pre-qualification test: displays the condition of the battery before charging and measures environment temperature. The ampmatic charge program is selected according to temperature and battery condition.
  • 2. Low Volts recovery: The safeT protection mode controls charging during this sensitive battery SAVE stage to ensure that an over discharged battery will be correctly and safely recovered.
  • 3. Bulk charge: 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 and unnecessary charging is prevented of a battery that cannot be recovered.
  • 5. 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 batterys overall power delivery.
  • 6. Charge verification: 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.
  • 7. Voltage retention test: is conducted for 30 minutes during which no charge current is delivered with 5 possible test results indicating the batterys general state of health.
  • 8. Charge maintenance: 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.
