OptiMate 5 is the all-in-one tool for 12V battery care at home. It diagnoses, recovers, charges, tests and optimally maintains, automatically. OptiMate 5 retains all the fully automatic, 100% safe, easy-to-use characteristics, of the 1.5 million OptiMates produced since 1995, but adds a powerful 2.8 Amp output to take care of larger batteries. Forgot your battery throughout the winter? OptiMate 5 will recover it from deep discharge and optimally recharge it. Then it will check that the charge delivered is the best possible before then checking how well the battery can retain the charge. And tell you its status, at a glance. Of course, it will then maintain your battery at full charge safely for months at a time, prolonging its life by up to 400%--reducing waste for a better environment. No wonder 10 major constructors recommend OptiMate.

An all-in-one tool for 12V battery charging and maintenance

How It Works

• Safety check: OptiMate 5 will only activate if connected to a battery that has at least 2V of charge.
• Desulfation and recovery: if the battery’s resistance is abnormally high due to sulfation, a voltage of up to 20V is automatically applied to overcome this to recover very fl at or neglected batteries (disconnected from the vehicle) until they are able to accept the normal charge program.
• Bulk charge: a constant current of 2.8A brings the battery close to full charge.
• Charge verification: as soon as the rising resistance causes the charge voltage to reach 14.3V, the voltage is limited at 13.6V for 30 minutes while the circuit monitors the actual voltage and the current absorbed by the battery. If within 30 minutes the achieved charge is less than optimal, the program goes back to bulk charge and the process repeats.
• Charge retention test: when the charger confirms that an optimal charge has been achieved, the first check for battery (and connected system) power leakage begins. Depending on the voltage retained during 30 minutes, an “OK” (green LED) or “not OK” (red LED) test result is displayed. These 30 minute test periods repeat hourly until the OptiMate 5 is disconnected, so that the battery status indication is continually updated.
• Charge maintenance: during alternate 30 minute periods, at a float limit of 13.6V the battery is offered charge current (up to the maximum) it needs to sustain it against any small connected loads or power leakage and against natural self-discharge.

OptiMate 5 can stay connected to the battery indefinitely and the battery will be safe and 100% charged. (Standard filler cap batteries need their liquid level checked regularly during long term connection.)
