I use my GPS only on occasion. Is it better to leave on charge through my computer (which is on almost all day) all  the time or disconnect it after a full charge?

    Hi there,

     

    Therefore you'll have to know something about batteries and charging functionalities:

     

    • Every battery discharges if it is left in a device as the electrical circuit is closed even if the device is turned off.
    • Most chargers stop charging after the battery is fully charged. The charger restarts the process of charging if the battery looses part of its charge again. Some chargers start even if the battery is charged to 99%, others have a functionality to only start charging if the charge hold in the battery sinks below a preset percentage (i.e. 95% or 90%). This is done to reduce the number of charging processes as each battery only has a certain number of processes until it dies. Most batteries today allow at least 1000 charging processes the better ones even up to 2000-3000 processes. If charging your device via USB it will stop charging if the battery is fully charged. But I do not know at which percentage of a completely charged battery it restarts charging.

     

    I always charge my device before starting on a trip via my computer. If it is a longer trip I always connect my device to my car charger before turning it on.

    If I don't plan a trip I disconnect the device from my computer and connect it usually once a week to receive map share updates as well as the new GPSfix file. At those times I leave the device connected to my computer for about 2 hours to get it recharged.

     

     

    Regards

    Lars.

    I agree. The worst is to leave it discharged for any length of time.

    Hi,

     

    if you're charging your device via your computer's USB port it'll take up to 4 hours to charge completely depending on the remaining charge before connecting the device to your computer and whether you leave the device turned off or turn it on.

     

    I found no specific option so far to see how much charge is left in detail. I just connect the device once a week for about 4 hours and use the car charger every time I use the device as well.

     

    As the device's use Li-ion batteries there's no memory effect to fear. Only completely discharging the battery will damage it.

     

     

    Regards

    Lars.

    PRipley, if your device is disconnected from a power source you can see your battery status by taping the lower right window and you will see a battery partially filled with color. Green for a safe charge, orange if it is getting close to half charged. Most units will operate about 2 hrs on the battery only. Apparently some units do not complete shut down when you turn them off, and will slowly drain the battery when not in use. Like Lars, I usually use mine plugged into the car when driving; otherwise plug it in for updates. Never a problem.

    It is better (quicker) to charge with it turned off. When you turn it on and disconnected from charger, touch the lower right corner and you will see your battery status.

    Why isn't my Tomtom re-charging ? Just purchased less than one week ago and have tried charging it on my computer for several hours. Doesn't seem like it wants to charge..any suggestions?

    How do you know it is not charging? Does it not start up? Will it charge in your car? You should keep it plugged in to your car while driving at all times. If you have IQ Routes, that will not work unless plugged in.


     


    When plugged in to your computer, is the green light on the bottom of your TT lit? If not, you are not getting power. If you are getting power, the charge goes quicker if the TT is turned off.

    it depends on where you connect - you need to connect on the main computer, i think it's the USB port.  it won't charge if you connect on the computer screen.  hope that helps.

    Hi,

    on a USB hub it'll charge as well. But I always recommend using a USB port directly on the computer as that'll definitely allow you to update your device as well and usually also provides a higher maximum current so your device gets charged faster.

    If the device stays turned off it may be that it also gets charged via a USB port on the screen. But those ports usually shouldn't be used for charging as they might break earlier because of not being able to supply a current high enough.


    Regards
    Lars.

    We have 2 answers here. One says the battery charge will last 4 hours and the other says 2 hours. Which is it? Obviously settings like display brightness will affect charge life somewhat, but I'd like the best answer please. I HAVE to operate on home charge while in the car because the 27 year old car's cigarette lighter does not treat electronic gadgets very well. I too, am annoyed at the difficulty in finding battery status screen. TomTom's assumption that all users use the device in a car, attached to a power source, is unfounded.

    You'd never get close to four hours of battery charge even with a brand new battery. In my opinion. Maybe two.


     


    And TomTom provides a cable for the car since indeed the device is meant to be used in the auto and connected to the cable.


     


    You might want to get an AC charger (for usb devices) at a Future Shop or Best Buy near you and charge your unit overnight, every night. Then, use it the next day in the car, remove at the end of the day and repeat the charge cycle.


     


    Or, just get your cig lighter outlet repaired.


     


    Just a thought.

    I have read this discussion with interest, because my GO Live 2535 TomTom has never given me any trouble until it stopped working today. The top left on/off button was glowing orange instead of green. It wouldn't turn on. So when I eventually made it home, I connected the Tom Tom to the USB port of my computer, and the on/off button turned green. However I still cannot turn it on, and when I try the light turns orange again. Does this mean that my faithful Tom Tom has died? Or that it is not charging properly.

    I think this means your battery is low on power, and may not accept a charge. Try leaving it charging (device off) overnight and see if it will turn on then. It might be wise to hold the on button till you hear  the double drum roll to do a reset during the initial try to turn it on.
