Optimate 5 Select Automatic Battery Charger

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 helps you achieve efficient charging and stable results with batteries between 3Ah and 120Ah (or 160Ah for 6V).Low-Volt Start with Two-Step Desulphation Recovery: This feature activates batteries from as low as 0.5V using a pulsed recovery phase followed by controlled desulphation, helping you bring neglected batteries back to a serviceable condition and improving their ability to accept and hold charge afterwards.Eight-Step Charging and Maintenance Programme: This programme starts with a voltage safety check, then moves to battery testing, recovery, charging, cell balancing, performance testing, and continuous maintenance, giving you a structured system that stabilises the battery and maintains charge during long storage periods.Automatic Current Adjustment: This system measures the internal resistance and condition of the battery and sets the charging rate accordingly, helping you reduce stress on smaller batteries while ensuring larger ones receive enough current for a full and steady recharge.Battery State-of-Health Testing: This function evaluates charge retention after the optimisation phase and provides visual status feedback, helping you understand whether your battery continues to hold charge effectively so you can plan replacements when needed.Sustained 24/7 Maintenance Mode: This mode supplies a controlled float charge and periodic monitoring, which helps your battery stay at full charge during long periods off the road and reduces deterioration associated with inactivity.Full Electronic Protection System: This protection includes spark suppression, short-circuit shut-down, overcharge prevention, and compatibility with vehicle electronics, helping you connect and disconnect confidently without risking damage to the charger or battery.IP54 Weatherproof Case: This housing protects internal components from dust and water spray and is rated for use down to 40°C, supporting operation in garages, sheds, or outdoor environments where temperatures and conditions vary.Energy-Saving Stand-By Function: This system uses less than 0.5W when idle and adjusts power draw throughout the charging cycle, helping you reduce unnecessary energy consumption during long-term maintenance.Global 100 240V Input with High-Efficiency Circuitry: This wide-range input works with different mains supplies and uses a CEC-listed high-efficiency design, allowing consistent function in various locations while keeping electrical consumption steady.SAE Charging Lead with Weatherproof Battery Lead Included: This setup gives you a permanent connection option for vehicles stored for long periods and a clip set for occasional charging, offering straightforward installation for regular or intermittent use.You use the OptiMate 5 Select when you want a charger that restores weak batteries, maintains charge during long storage periods, and gives you clear information on battery condition. The automated steps and recovery functions help you keep everyday vehicles ready for use without regular manual checks. Its controlled charging process and long-term maintenance capability make it a practical addition to your garage or workshop when you want a reliable tool for ongoing battery care.
