Tomtom Go 720 Replacement Battery

DraySoft · Posted: Sat Dec 06, 2008 4:54 pm Post subject: Tomtom Go 720 Replacement Battery

Hi All,
Has anyone been able to purchase a replacement battery for Go 720.

I have had mine since they first came out and use it every day in my ‘white van’. It is constantly charged in a Carcomm cradle with a TMC connector.

If I try to use it first thing in a morning without putting it in the cradle it lasts about 10 minutes then it shows the ‘flashing battery’ symbol then switches off.

Regards,

Draysoft.

Is it still under guarantee? (some TomTom units were 2 years)

The two year warranty stopped at the x10 devices, all units since have been a one year when you read the licence text file on the devices - Mike

Hi DraySoft
I see that no one has been able to come up with an answer to your question. So, where do we 720 users get a new battery from when we eventually need one. Until I read your topic I had never given any thought to the subject of a new battery but nothing lasts for ever.

Or contact the SatNav Shop http://www.satnav-shop.com/index.php?ln=en&pg=5. I don't think replacing the battery is a straightforward diy job.

Hi Calomax
I must admit that I have never seen any instructions as to how one opens up the device and carries out the replacement.
I did operate on my Dell PDA and on my Ipaq PDA two or three years ago but I had followed advice (from this Forum) prior to opening up the innards.

About the battery, is it possible to get a battery with greater lasting power?
My 720 is only about 2 months ld now, but when blue tooth is on for hands free and running on internal battery it only lasts about an hour before battery is wel down and whilst the TT still works, using mobile via bluetooth is not possible as it requires more power than battery able to deliver.

I have not looked anywhere, but thought it might be possible as you can get bigger bateries for PCs, mobiles and the like.

Its actually much easier to get at the battery on the x20/ x30 but it does still involve removal of ribbon cables etc. If you are slightly concerned about undertaking any of the steps outlined below don’t touch the device and pay some one else to fix it.

If you break your device its not my fault, so don't come back shouting here!

Anyone looking to change the battery in their device should read through the entire thread to get a few ideas about removal of the battery cell which isn't easy.

Get it wrong and you could rip copper tracks off the PCB, if you accidentally cut in to the battery then it will probably catch fire or explode.

You will need a Torx No5 bit/ screwdriver and a pair of fine tweezers would be handy but not essential.

Remove the SD card if fitted.
Lay the device screen side down and remove the two screws from the rear of the device:

Insert your thumb nail between the silver trim and black surround near the top of the device, the main unit will start to ease from the black case:

You can now easily extract the main unit, take care not to exert force on the interconnecting cables. Note the main screen ribbon cable, under the black tape is a small PCB multi way connector, remove the tape for access.

At both ends of the connector strip is a small fragile plastic lever, these need to be eased upwards to release the ribbon cable, they only need to move a few MM in order to release the cable. The other two core plug can stay connected for this job so leave it alone.

You can now see the Torx head screws securing the main board into the housing, remove each of these, once they are all out ease the board from the housing, again the speaker wire stays in place so don't go pulling it around too much. With the main board removed turn it over to reveal the battery.

Slightly closer view of the battery and the three pin multi way plug it is fitted with.

- Mike

Edit Once to add notes about reading through entire thread and battery removal issues - Mike Alder
