Optimate 3 Motorcycle Battery Charger

A fully automatic battery charger conditioner and maintainer suitable for 12v batteries up to 50Ah capacity cars motorcycles quad-bikes and jet-skis etc.
OptiMate 3 is completely automatic and comes with an easy connection system included so all you need to do is connect it up and let the OptiMate do the rest. It is 100% safe and uses only a tiny amount of power to make sure that your battery is in the best possible condition at all times.

Whats in the box:

OptiMate 3 charger with UK mains plug.
Waterproof connection lead for permanent installation.
Crocodile clip set for temporary connection.
Instruction manual.

What it does:

  • When the OptiMate is connected to a battery it automatically switches on and analyses the condition of the battery.
  • If the battery is weak sulphated or has a very high internal resistance a recovery mode is activated which attempts to restore the battery to a usable condition.
  • When the battery is ready to be charged the main or Bulk charge phase then charges the battery at a constant current until the battery is close to full charge.
  • To complete the charging process the charging voltage is then kept at a constant level for a final or absorbtion charge during which the charging current gradually diminishes as the battery slowly reaches its maximum charge level.
  • Once the battery is fully charged the OptiMate then checks that the battery will hold its charge sufficiently before indicating a green light which means that the battery is fully charged and ready for use.
  • A regular sequence of tests are then repeated at hourly intervals during which the green light flashes. If during a test sequence a small loss of charge is detected then the OptiMate will charge the battery again for a short time until the green light comes on again.
  • If at any time during connection the batterys condition drops below the level required for reliable use then a red light will show and this indicates that the battery might need replacing should be checked by a specialist.
