This Optimate Pro 8 charger is in very good condition and has been in regular use at our gliding club, charging the 12V batteries for  the radios, and nav equipment, etc. We have just changed over and invested in a load of lithium batteries and chargers, hence the Pro 8 is now surplus to requirements.
Looking on-line, the current new price is over £600.00, so save a lot of money with this very good used unit.
This is the charger only with mains (240V) lead, there are no connecting leads to go to the batteries as these have remained in service with us for the lithium setup.
