CTEK CS One, 12V Battery Charger, Smart Battery Charger, Car & Motorcycle Battery Charger, Battery Maintainer with Adaptive Charge, Non-Polarity Application And Clamps

• Charge any battery in any situation: Features CTEK revolutionary APTO technology to charge any battery quickly and easily. It automatically detects any type and size of 12V lead or lithium (LiFePO4) battery, determines what the battery needs, and then offers a customized charging schedule to maximize battery performance.
• Easy to use: no buttons to press or modes to select. Simply connect CS ONE to any battery and let it do its job.
• APTO Technology: Adaptive Charging Technology (APTO) asks the battery what type it is, its size and the state it is in. It then automatically provides the most appropriate charge for the battery and signals how long it is left until it is fully charged.
• Non-polarity clips: Automatically calculates which clamp is at which charging point so you never make a wrong connection again. Also, the tweezers are anti-spark, so don't worry if you accidentally touch them.
• Countdown indicator: Clearly shows you when you can restart a dead battery and how long it takes for the battery to be fully charged.
• Additional features with the CTEK app: The app unlocks functions such as "RECOND" to restore life to heavily discharged batteries, "LITHIUM WAKE UP" function for lithium batteries with low voltage protection (UVP) and "SUPPLY" to convert CS ONE into a 12V power supply.
• Ambient temperature setting: detects hot or cold and automatically adjusts the output voltage.
• Automatically detects faulty cells: You can tell if your battery cannot be charged and will notify you.
• 5 year warranty
