Batteries leaked acid. How do I crack open to clean?
I left the the batteries in my 8 year old Garmin GPS 12 had the batteries leak acid. Can anyone tell me how to crack open the casing? There is a very small screw at the bottom of the unit but it seems to just hold the battery case lid. There is also a small hole in the back (under the rubber cover but a scre driver just goes right through. I can't feel a screw in there. I would like to open the unit and clean it out so hopefully it can still be used. I called Garmin Tech support and they said it was worth a try but no one could tell me how to disassemble the unit.
Re: Batteries leaked acid. How do I crack open to clean?
Just pry it open (gently) with a flat bladed screwdriver. It's glued together with silicone seal. To put mine back together, I scrapped thoroughly to get the old stuff off, crazyglued the corners, then later filled the gap with silicone sealer. Easy.

Your Garmin device is probably over 12 years old. go get a new one. you have already gotten more than your moneys's worth out of this device. I recommend replacing it with an eTrex 20 or if you want a magnetic compass and better sensors an eTrex 30.
Otherwise, replace the batteries, open it up and replace any coin cell batteries in there as well.
The on/off switch on these were problematic.. so you might want to look at the linkage and switch before digging deeper, below.
Corrosion is a problem. If you can clean it up, you should. If the corrosion is a result of a leaking battery, you should disassemble the device as far as possible to allow access to areas that have been contaminated with battery acid. I like to use a q-tip dampened in a mixture of baking soda and water (about 10% baking soda and 90% water). Battery acid conducts electricity and must be removed. Anywhere it is results in changes in the values of components and can cause a great deal of problems.
You may also be able to exchange for a modest sum with Garmin for one of their rebuilt units - if available.
try swapping out the batteries, no harm in opening it up with a screw driver (will void the "warranty" that expired 12 years ago) check if there is an internal battery (usually a coin cell battery like cr 2025 or CR2020) otherwise it is dead and time to get an e-trex 30... great simple little unit with lots more features
The acid from the leaking battery most likely shorted out the circuit board. You can trying cleaning of the acid spill with a little alcohol on a Q tip. The batteries are probably also no good and you will need to replace them also. If this does not work you can try taking the unit apart and cleaning any further acid that has leaked to the inside.

I had the same problem and it took me some time to make my cable. I got this info from fix ya. Reload the software for your unit, I googled garmingps12 and went to downloads from the garmin selections.The software is not compatable with vista, so I ended up using my old computer to do the job. http://pfranc.com/projects/g45contr/assemb.htm
This web site gives good information on making your own cable.
I hope all works for you as it did for me. justaxiom
Try connecting it to USB and powering it up, to confirm that unit still works overall. You probably damaged battery connectors. Check if you can clean the connectors better, otherwise you may need to do some soldering to fix them, by yourself or n a repair shop. Check with Garmin if they have suggestions: a leaking battery should not disable a GPS.
The GPS 12 has an internal battery soldered to the board inside the unit.
I have replaced about a dozen of these over the years,
The problem is caused when the unit is stored for a long time without batteries.
The internal battery is not a rechargable.
You have to use a screwdriver in the crack that joins the 2 parts of the case and break the seal to split the case open.
This will of corse render the waterproofness of the unit void.
You then have to unsolder the internal battery from the board and find a replacement.
It is a tagged lithum battery, I can't remember the model at the moment.
Inside you will also notice the surface mount Intel 386 Chip. which is the main processer.
This has nothing to do with the battery but I found it interesting that a chip in a computer from the mid 80s worth over $3000 then, still has a use.
When you have soldered the new battery into place you need to either glue or tape the unit back together. Be careful not to damage the other parts around the battery.
Always keep charged batteries in the unit when not in use.
Stay clear of rechargeable NiCads as they supply to low voltage and you may experience cutouts ? Use good quality regular alkaline batteries. Check battery terminals in gps (both ends) for corrosion/rust and clean if necessary.
