OptiMate 5 Select is the all-in-one tool for 6V & 12V battery care at home. OptiMate 5 Select has all the automatic 100% safe and easy-to-use characteristics of the 1.5 million OptiMates produced since 1995, but adds a powerful 4 Amp output to take care of larger batteries.

Forgot your battery throughout the winter? OptiMate 5 Select will recover it from deep discharge and optimally recharge it. Then it will check that the charge delivered is the best possible before 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%.

How it works

1.     Safety check: OptiMate 5 Select must be connected to a battery (retaining minimum 0.5V) to activate its output. 
2.     Desulphation and recovery: if the battery's resistance is abnormally high due to sulphation, a higher voltage is automatically applied to overcome this so as to recover very flat or neglected batteries until they are able to accept the normal charge program. 
3.     Bulk charge: a constant current of 3A (4A in 6V mode) efficiently brings the battery close to full charge. 
4.     Charge: Pulse absorption, cell equalisation (balancing) and charge verification: Charging is delivered in controlled pulses that automatically equalise cell voltages, until the current has reduced below 400mA which is indicative of a battery that has reached full charge. 
5.     Charge retention test: when the monitored parameters confirm that an optimal charge has been achieved, the first check for battery (and connected system) power leakage commences. 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 Select is disconnected, so that the battery status indication is continually updated. 
6.     Charge maintenance: during alternate 30 minute periods, 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 Select can stay connected to the battery indefinitely and the battery will stay cool and safe. And optimally charged. Of course.
