(we have all felt static, rubbing the balloon on the jumper, your hair near a rug flies all over, sometimes you hear/feel a (small click) when touching metal, or feel those tiny shocks, when touching metal, or the car sometimes, this is ESD, if you give any Electronic device's insides, one of these clicks, you are risking turning the Item into a paperweight, so if ever working with Electronics, for the sake of $10 dollar's, buy the kit, no problem then. (Ground/earth yourself)
Before doing the procedure, bench setup is needed, lay all parts in a line for easy fitting, to remember where all parts go, and in what order, good memory is needed.
Step 1. Buy the new Battery
EBAY(new only)
Battery Junction
2, Remove the Fascia/faceplate off the front of the Pilot
remove the 4 Philips/posy screws
3, pull out the front section of the GPS, critical to remember how parts are being removed, for re-assembly.
4, unscrew the 2 small screws holding the battery in place, the battery is behind here, then UN-connect from the Internal circuit board. and remove it.
5, Remove the protective heat tubing from the Battery,
6, un-solder the connection's. (take care not to overheat the battery)
7, Solder on the new battery, (careful not to overheat the battery again)
8, Make sure you insulate the new soldered joints before using the heat-shrink tubing
9, use the heat-shrink tubing to protect the battery again, hardware store B&Q, Home depot, 3/4 or 1 inch tubing,
10, use a lighter to shrink the tubing back to the battery tight
(being extra careful not to overheat the battery)
11, put the battery back inside screwing the 2 screws back into the metal plate, holding the battery in place.
12, Re-assemble the unit back together, checking everything went back as stripped out. Camera phone is good for taking pictures of the stripping part for you.
Declaration:
Please be careful as I cannot be responsible for your Action's, although the steps are here for you, it is your responsibility what you do, and how you do this, I have used this procedure to replace the StreetPilot batteries before, which takes, 10/15 Min's to do, but I would advise to take your time, there is no rush, Soldering Iron is needed too as well as the ESD kit for grounding purposes, Soldering Iron to solder the Battery terminals to the battery. It is assumed that you can do basic Soldering and stripping of a unit and rebuilding, this is Electronic assembly.
