  • The Foxwell BT100 is a simple to use car battery analyser, which gives a quick assessment of the health and charge level of your battery.

    The tool will immediately give a voltage reading on connection to the battery.
    Then by simply answering a few on-screen questions (such as whether the battery is in the vehicle, the type of battery, the battery standard and the rated CCA), it will give a more comprehensive assessment.


    The BT100 will report:
    • Measured voltage
    • Measured CCA (Cold Cranking Amps)
    • Rated CCA
    • SOC (State Of Charge) percentage
    • SOH (State of Health) percentage

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.
