battery life

Well, what about a way of completely turning off your TomTom? When you turn it off normaly, it keeps draining the battery and flattens it out in about 2 weeks... not good for storing it when it's not in use. :(
 
What we need is someone brave enough, and skilled, to open the TomTom One and show the battery thats installed. Then, it may be possible to figure out if a larger capacity battery is available, one that also fits into the space available.

At the moment, I would only open mine if I were replacing the battery with something bigger.

Caveat: this would undoubtedly VOID YOUR WARRANTY.
 
I think the battery life in the TTONE ia :confused: JOKE! I can charge mine, shut it off, and turn it on a few days later and the battery level has already gone down, what the heck?

A bit tricky to open but here are some pictures of the inside.

You're definitely brave :) but thanks for sharing that. Is that battery something you can buy in retail stores?
It's a Maxell lithium-ion battery -- 3.7V at 1100 mAh

Need to find one of the same physical size and much greater capacity!

Only one that may fit - bigger is the ICP803443 0.5mm THICKER
But where to get it ?

The lithium-ion battery appears to be popular for cameras. Perhaps a full-service camera shop would have a replacement chart.

However, consider that to add 50% capacity/time, you'd need a 1650 mAh battery and I don't know if they make one that large in that size package.
 
Heat buildup and charging circuitry specs are a concern...

I don't think it was a strategic move by TomTom to put a wimpy battery in the One. More likely it was a consideration of the necessary size, charging rate and heat tolerance of adjoining components.

These issues have been dealt with for years by palmtop computer users whose hardware didn't have a user-serviceable battery. It was a perpetual hunt for a battery that would work with very specific constraints. Typically, there was a realization that the manufacturer had the battery custom made to their physical and electrical specs. In other words, it was virtually impossible to find a substitute battery that didn't require some hacking of the hardware or the circuitry. I saw some great examples of the Frankenstein method of hammering in a generic battery. Yikes!

Realistically, we all have to prepare for the day that our TT battery finally passes on. Hopefully, when our unit gives up the ghost, the latest whiz-bang GPS device will be calling us.

How did you get it open?
Power off and remove the SD card. Remove the 4 screws with a T-9 torx and using a case separator gently insert at the top and pry apart. There is noticeable resistance until one side pops loose. Then carefully separate the halves.

If you use a screw driver to pry at the top you have a good chance to gouge or mark the outside. I used the case separator that came with a battery for the iPod (it will also work with iPhone).

Have fun...
 
Energizer battery booster

It's easier to buy the $25 Energizer battery booster from Radio Shack or similar. It just plugs into the normal mini USB connector!:)
 
Forgive my ignorance, I have only had my one for a few weeks. A two hour run time seems to be plenty. How often to you guys run your TT outside of your car? I have a Magellan that I use for geocaching with it's lcd b&w display it runs a long time on a pair of lithium "AA" batteries. The TT with its color back light display needs a lot of power to run it.
If you need a longer run time outside of your car or away from your PC there are many different kinds of battery packs with a usb port that will run your TT . I have one that I got for $5.00 that holds 4 "AA" batteries and a usb port that runs all my usb powered devices. With lithium "AA" batteries in runs my PDA for while. I use it as an MP3 player.

I don't like the in-car power supply because of the location of the power socket (in the center armrest bin) - the cord runs over the radio, etc. I sure would be nice to have a 5-hour battery.

The TT battery is rated at 1100 mAh if I recall correctly and rechargeable lithiums at around 2400 mAh for a couple of bucks each are on the market. I daresay that a battery pack of four of those would be excellent!!

I never thought of that. I have the power cord hidden and it does not bother me.
