  • Ring 12A Smart Charger – Charge and Diagnose

    Get the fastest, most extensive care for your car battery with the multi award-winning Ring 12A Smart Charger, which has the highest amp of the Ring Smart charger range with a charging current of up to 12 amps. This charger also carries out four tests to check its health making this a powerful, efficient way to analyse, recharge, repair and maintain your car battery. The Ring 12A Smart Charger has been named an Auto Express Product of the Year, and won the Automechanika Innovation Award 2015.

    Suitable to use on lead, gel, calcium, AGM and EFB batteries (including those with START/STOP technology) the Ring 12A Smart Charger analyses voltage status, alternator recharging performance and battery start power performance, with results are shown on the LCD screen.

    The battery charging and reconditioning is a fully automatic seven stage process:

    1. Desulphation - Reduces build-up of sulphate that can damage battery performance and lifespan.
    2. Soft Start - Gently introduces voltage to prevent shocking the system.
    3. Bulk Charge - Smart Charger automatically selects the fastest charge cycle for your battery.
    4. Absorption - Adds the last 20% gently so it is absorbed and held by the battery.
    5. Discharge Test - Checks how quickly the battery is losing charge.
    6. Recondition - If it is not retaining charge, the battery is reconditioned to improve performance.
    7. Float - Maintains battery over long period without overcharging. Ideal to leave plugged in over winter.

    Please note that the Ring 12A Smart Charger is specifically designed to charge and maintain batteries – it does not jump start or recharge completely flat batteries.

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
