Optimate Lithium Select 12V/16V Automatic Battery Charger

The Optimate Lithium Select 12V/16V Automatic Battery Charger helps you charge, recover and maintain LiFePO4/LFP lithium batteries used in your vehicle. You use selectable voltage modes, a ten-step automatic charging programme and integrated low-voltage recovery to bring the battery to a full and stable charge.Discover the key features of this charger:Selectable 12.8V or 16V Charge Voltage: You choose between a 12.8V setting for 4-cell lithium batteries or a 16V setting for 5-cell lithium batteries, and the charger stores your selection even if AC power is lost, which helps you maintain the correct voltage profile and achieve consistent full-charge results.Ampmatic Current Control: The charger adjusts its output automatically from 9.5A at 12.8V to 7.5A at 16V, using feedback from battery condition and capacity to match the charge rate accurately, which supports efficient charging and stable long-term battery function.Ten-Step Automatic Charging Programme: A controlled sequence covering low-volt start, test-before-charge, temperature check, ultra-low-volt save, low-volt save with cell monitoring, cell-damage testing, cell-balancing charge, optimise mode, post-charge testing and 24-7 maintenance uses defined voltage and current stages to restore, verify and maintain the battery, giving you predictable charge management from initial assessment through to long-term upkeep.Three-Stage Low-Voltage Save Function: A recovery system starting from 0.5V applies staged current and voltage adjustments to reactivate a battery that has entered sleep or deep-discharge protection, supporting you in bringing a depleted battery back into usable condition.Battery Management System (BMS) Reactivation: The charger triggers the BMS wake-up process through controlled low-volt pulses, allowing a protected or dormant lithium battery to accept charge again, helping you recover batteries that would otherwise remain inactive.State-of-Health Testing: Built-in diagnostics evaluate voltage stability and cell behaviour before, during and after charging, presenting you with accurate insight into overall condition so you can address issues early and maintain reliable battery operation.Electronic Safety Controls: Spark suppression, automatic shutdown when the battery is disconnected or short-circuited, and protection against overcharging use electronic monitoring to keep the charging process safe, which helps you safeguard battery electronics and vehicle systems.IP54 Weatherproof Housing: A sealed, impact-resistant case rated for use down to 40°C allows you to use the charger indoors or outdoors, giving you dependable performance in varied working environments.Energy-Saving Operation: Stand-by power consumption under 0.5W and efficient 24-7 maintenance modes reduce unnecessary energy use, supporting cost-effective long-term battery care.Global 100 240V Input: A high-efficiency power supply compatible with worldwide mains voltages enables you to use the charger in different locations without additional adaptors, giving you flexibility when maintaining batteries away from home.Extended Cable Setup: A 180cm AC lead, 180cm charge lead with SAE connector, and included weatherproof battery lead and clip set provide practical reach and connection options, which help you set up charging equipment easily around your workspace.This charger supports you in restoring, maintaining and monitoring lithium batteries so you can keep your vehicle ready for regular use. Its selectable voltage modes, diagnostic tools and staged recovery functions give you a structured system for handling everything from routine top-ups to deep-discharge situations. It is a practical addition to your workshop or vehicle equipment, offering a smart way to manage lithium batteries accurately and maintain dependable performance over time.
