The OptiMate 5 Select helps you recover, charge, test, and maintain 6V and 12V lead-acid batteries, supporting everything from small starter units to larger deep-cycle batteries. It achieves this through an automatic eight-step programme that manages voltage checks, desulphation recovery, controlled charging, optimisation, testing, and long-term maintenance using a 4A (6V) or 3A (12V) output.Here are the key features of this charger:Selectable 6V/12V Operating Mode: This mode uses a voltage verification circuit that confirms the selected voltage matches the battery s actual state and requires a manual override for low-volt 12V units, giving you controlled operation and preventing incorrect charging so your battery progresses through the charging cycle safely.AmpMatic 4A (6V) / 3A (12V) Charging Output: This technology adjusts current according to battery size and condition, applying higher current to larger or heavily discharged batteries and lighter current to smaller units, which hel
