I am about to change a knackered battery on my One XL but after removing the 4 screws it doesn't come apart,There is obviously some little catch or similar that I can't find!,Has anyone done one successfully?

I haven't found any specific descriptions with pictures for taking apart the One XL yet, but here's a written description:

1) Very first thing, make sure it's off and remove the SD card.

2) Remove the 4 TORX screws from the back.

3) Starting on the top where the silver plastic meets the dark grey plastic, using your thumb nail(s), or something NON-METALLIC so you don't damage the plastic, force your thumb nail(s) between the silver and grey plastic. Shouldn't be very hard to do.

4) Once you get that started, work your way down the sides. By this time, you should have about half an inch or so separating the top seams. Still using your thumb nail(s), separate the bottom. BE CAREFUL NOT TO PULL THE 2 HALVES APART VIOLENTLY. There are 2 connectors inside. 1 for the battery and 1 for the speaker. The speaker and battery are mounted to the rear section. Everything else is mounted to the front.

5) Gently disconnect the battery and speaker from their connections on the circuit board. You should be able to do this with your thumb nail and fore-finger (or whatever finger(s) you feel comfortable using).

6) Once you get those disconnected, you have 2 seperate halves. The battery is the rectangular item on the back half and is mounted to the back with a very sticky pad or cushion. Slowly and gently, using a screwdriver on the edge closest to the bottom, pry the battery out. Take your time with this. It will start to come out. Then work your way to the top. When I got mine out, 99% of the sticky pad remained in the rear shell so I should be able to re-use it. If not, you'll have to use something that will hold it in place.

7) Reverse the procedure to install a new battery and close the case. I think the MOST IMPORTANT THING IS TO TAKE YOUR TIME. DON'T RUSH.

Another description I found of the battery replacement process:

1) Took out both torx screws on the back. Easy
2) Carefully remove front screen (top first) IMPORTANT: Watch the flat cable which connect the logic board to the touch screen.
3) Removed the screen flat cable and the mic connector with extreme caution using a plastic flat screwdriver.
4) Removed the 4 torx screws at each corner of the board.
5) Separated the logic board (top first) and removed speaker connector.
6) Using the plastic flat screwdriver, separated the glued original battery from the logic board.
7) Glued the new battery to the logic board using an acid free glue.
8) Re-assembled TOMTOM and power-on was successful.
---------------------------------------------------------
And a third from the US:

Replacing the tomtom1 battery has its challenges.
I bought a replacement battery from RadioShack, catalog number 55026605 for $26 + S&H. It's manufactured by Dantona, model PDA-192LI.
You will also need a T8 torx driver. I purchased a mulit-function driver from my local hardware store (Lowes) manufactured by General, known as the "UltraTech Tool System" for about $18.
Disassembly:
1. Remove the SD card from the device.
2. Remove the four T8 screws from the rear of the tomtom1.
3. Read though this step in its entirety... this is important reference information.
A. The tomtom1 unit is going to separate into two pieces, the front part (FP) is silver and the back part (BP) is dark grey.
B. The FP contains 98% of the electronics and the screen.
C. The BP hosts the speaker and battery.
D. The speaker and battery are connected to the FP via wire and miniture connectors.
E. You will note that the external antenna connector (BP, upper right corner) is flush with the BP surface.
F. You will also note that the miniture D-connector on the unit (BP, bottom) is also flush with the BP surface.
G. The BP is not removed by applying forces perpendicular to the face of the FP, rather the BP and FP are separated at the top and then the FP is lifted upward with respect to the BP.
4. Now that you have read all the steps in "3" above, separate the unit at the top about 5-10mm, ensure the sides of the BP clear the FP and then lift the FP away from the BP at an angle.
5. It is easier to manage the next steps if you disconnect the wires that link the the FP to the BP.
6. The battery is held in place by adhesive. Removing the battery is, IMHO, the most challenging part of this exercise. The original battery has a shrink-wrapped outer jacket (shiny black in color), and is held in place by a double-sided adhesive tape. I used a box-cutter to cut an incision along the corner of the jacket and then "popped" the battery out of the shrink-wrap. I then used a pair of pliers to grab the shrink-wrap and "tear" is away from the adhesive material. I removed the adhesive tape by scrapping it away with a bamboo skewer from the kitchen. Exercise caution and patience with the box-cutter, restricting your cut to only the shrink-wrap. Remember, a battery contains chemicals and you do not want them getting outside of the designed container.
7. Following successful removal, I put my new battery in the unit, and used a small dab of rubber cement to hold it in place.

Take your pick!

THIS POST shows exactly what is involved to take apart a Go720, which also mentions just running a fingernail round the edge to split the two halves.

And HERE is a warning note about the replacement battery size for a TT ONE.
