tecmate optimate 3 Battery Charger and Maintainer 4501351

tecmate optimate 3 maintainer, battery charger and optimizer, for 12V batteries for motorcycles and other vehicles with battery capacities from 2.5 to 38Ah.

NB. Not compatible with lithium batteries

Technical features:

  • OptiMate 3 connects to the 220/240V home network and to the battery, all other functions occur automatically
  • Allows the rescue of neglected batteries, verifying the battery charge in its initial state and checking that there are no defective cells present
  • Hold function for long-term storage, with a gentle hold cycle – 30 minutes of rest for every hour of connection



OptiMate automatic multi-step program:

  • It starts automatically when connected to a 12V battery that has a voltage of at least 2V
  • The OptiMate immediately checks whether the battery has sufficient voltage to launch the program, and whether it is sulphur-filled or not
  • In the event of sulphurisation, the OptiMate applies its "first aid" intervention in the form of a voltage of 20V** maximum, with a weak current for a maximum duration of 2 hours, to induce the battery to accept a charge safely «normal» and thus activating the main charging mode
  • When the battery parameters indicate that the charging progress is sufficient, the verification phase starts (exclusivity)
  • The OptiMate interrupts the power supply for 30 minutes and monitors the voltage of the battery, not powered during this period of time to check if the battery retains a sufficient charge to be able to start an engine
  • Finally, maintenance mode is activated

  • No risk of overheating: the «50%» maintenance cycle - fluctuating voltage and 30' test followed by a 30' break keeps the battery always ready but never overcharged
  • No risk of damage to electronic elements: The high voltage desulfurization mode can only be started if the battery has first been disconnected from the vehicle's electrical panel
  • Complies with all relevant EN and IEC standards and CE directives
  • Included in the package are multilingual instructions, cable with clips (SAE-74) and cable with eyelets (SAE-71)
