OptiMate 5 Select is the all-in-one tool for 6V & 12V battery care at home. OptiMate 5 Select has all the fully automatic 100% safe and easy-to-use characteristics of the 1.5 million OptiMates produced since 1995, but adds a powerful 4A/3A 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%.
