    Default ONE v3 Battery Change

    ONE v3 Battery Change (Similar also ONE v1 & v2)
    1x Attached PDF file

    You need a Torx 8 or T8 driver to remove the screws.

    Before you start:
    Remove any SD cards
    Backup the TomTom using the TomTom suite software supplied with the unit. You shouldn't affect any data on the unit but best be safe!

    Step 1: Remove screws and open case
    Turn the unit over. There are four T8 screws that need removing.

    Once removed use your finger nails or an old credit card to open the case at the top, it splits between the silver and grey section as shown. Once as shown the grey back section slider down off the unit to clear the SD card and USB port.

    Step 2: Lay out and remove old battery.
    Once the two parts are loose they are only connect by two sets of wires, one for speaker one for battery. You should be able to see the two wires and gently open the halves and lay down as shown.

    If you feel any resistance the wires are still retained in the cable clip and just need freeing up.

    Now you need to free the battery. It is held down with a sticky foam pad. I found that inserting a slotted screwdriver in the now empty hole for the USB connector allowed me to work it loose. Be careful as if you go silly you could puncture the battery (unlikely though).

    Once the battery is loose you need to disconnect the lead. This is a small three pin plug and needs to be gently pulled upwards away from the circuit board. You may need to work a small screwdriver in to release if very stiff.

    Step 3: Install new battery and close up.
    Once removed it's time to install the new battery. I managed to carefully peel off the old foam sticky and re-attach to the new battery. If you can't they use a double sided foam sticky pad or similar.

    Make sure you install the battery with the power lead to the top left as per the original. My battery is flipped here to show the sticky.

    Insert the new battery and attach the plug to the socket on the circuit board. The plug is 3 pin and must be connected the correct way. If you look at the plug you can see the pins are offset so in theory will only connect the correct way. However I'm sure with enough force you could mash it in the wrong way so take your time.

    Once done bring the two halves together like a book, and route the two wires in the cable clip. Then assembly is reverse of removal, slide the grey halve onto the silver half so the USB connector pokes out of the hole in the case. If it looks correct snap shut and screw back together.

    Step 4: Turn on, check and charge up.
    Now it's all back together plug it into a charger and turn on. If all has been done correctly it should power up as normal.

    Although the battery was in theory supplied charged when I went to the Status Summary sheet as per below it began to charge. I left it charging like this for at least 6 hours to ensure it was fully charged and to avoid battery memory.

    All your existing data on the Tom Tom should be as before, if by some freak chance you have lost any data they reinstall from the backup made at the start.
