Battery replacement for TomTom 710

I have found a trick for those bad battery ,but you lose your waranty
you need to open your tomtom , behind the screen you wil find the battery(for the Go 710 it is an 3.7 V ,2400mAh,samsung ICR18650-24)
you find 3 wires : red, black,yellow cut them of at the half of the wire size
, then cut off your car loader wire (tomtom)(5v), you will see again 3 wires inside :red,black,white
connect the red with red, black with black, white with yellow
(the best thing is to make a little hole in the cover to pass the wire, so it will be beter for closing the all thing)
I did it and it works pretty fine ,I had save 30 dollars ;) :D
I did in approximatly 30 min
remember you will have no battery any more and no waranty of tomtom!
It only whorks then with your car loader tomtom

Here is a video that demonstrates how to replace the battery:
The company that produced the video sells a kit which includes the battery and tools necessary to do this yourself if you'd like. See: http://www.newpower99.com/ProductDetails.asp?ProductCode=TOMTOM+GO+510&Show=ExtInfo I swapped the battery of a friend's dying GPS using the aforementioned kit and all went well. His Go 510 is back up and running smoothly.
Hope this Helps, Tim

My GO710 looks to have a dead (faulty) battery when it hasn't been used for a while ( I also have a GO720 now). I have found if I leave it on charge for a long period, say 1 day, then disconnect/reconnect the power a few times it comes back to life and can be charged as normal. I have done this about three times over the past 18 months, it comes good each time.

You need to remove the front facia plate, then the four T6 screws from the rear. The main body of the tomtom will then come out (with a little help!) You then need to remove the screen (small screwdriver) and the two electronic boards (T6 screws) the battery will be visible right in the center of the unit. You unplug the connection and then the battery just un clips. It is quite an easy process though make sure its deff. the batt 1st!! I replaced mine and it didn't change anythin, still wouldn't charge correctly came on for short bursts and then the low batt light would come on again. I then found out it was the pins on the main connection that were at fault and they can't be changed!! TYPICAL!!!!!

I bought a brand new battery of of ebay. Installed it and my GO710 fired right up. After about 2 hours it was dead. The problem was the charging circuit which is part of the motherboard and not the battery. I decided to try bypassing the battery which apparently also bypasses the charging circuit. Works like a champ now as long as it's plugged in.

My TomTom Go 710 was not switching on but the green light would come on when charging. I replaced the battery and it worked fine....for a couple of hours. It then went back to previous state. I then followed the procedure to bypass the battery and it has worked a treat.

Just to say, I passed the cable to the connector on the unit through the same hole as the speaker cable but i had to enlarge the hole using a small file. I made a hole in the casing to allow the cable to come out from behind the speaker.

It is a fairly straightforward job when you have the tools ( T6 bit, small file, wire cutter, soldering iron (to connect the cables), drill to make hole in casing) and should take 30 minutes.

I had a Tomtom 710 with the battery problem as above, i 'hardwired' the car charger, and tadar it works a treat, i drill a hole in the side casing inline with the end of the battery, through both plastic and Ally housing, threaded the hardwire through both bits, soldered to the battery wires and refit in reverse.

You can buy the battery and replace yourself

You cant you have to send it in.
