DISCLAIMER.
Information provided here is based on my experience. I take no responsibility whatsoever if following this instructions damage to the equipment or bodily injury occurs. If you decide to perform the battery replacement on your own you are responsible for all your actions.
I have 30+ years of experience with electrical/electronics equipment so this task was very easy for me. In my opinion every weekend hobbyist can do it.
Now what to do.
1. Order a new battery. I have ordered replacement battery from this site: http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=1139. It was LG Li-Ion 18650 3.7V 2400 mAh Rechargeable Battery with Tabs. Original battery is 1,800 mAh so the replacement should last longer.
2. Take the screen cover (faceplate) off and unscrew 4 screws. You will need small Philips head screwdriver.
3. Pull off the front of the GPS (see pic. Be carefull with the GPS antenna. Make sure you remember its position so it is easier for you to assemble it later.
4. Unscrew 2 small screws holding metal strip. The battery is behind it. Pull battery out and disconnect it from the board.
5. Cut the heat shrink tube the battery is in and de-solder the joint.
6. Solder new battery. A small 15W soldering iron will do the job perfectly. Make sure not to overheat the battery. If needed use heatsink or place a small paper piece between the joint and battery.
7. Insulate the joints.
8. Put the new battery inside a heat shrink tube. You can get it from HomeDepot. It is ¾ inch diameter.
9. Use a heat source (I used a gas lighter) to “shrink” the tube. Again be careful not to overheat the battery as it may explode.
10. Put battery back into instrument and screw the metal band back onto the battery.
11. Assemble everything back together.
It took me approximately 15 min and I was taking pictures for this board! So it was worth it. Enjoy .
Some people asked to post photos of the antenna. Here they are. Added on April 17, 2007

| Nice! how long the original battery lasted? I know that excessive heat kills these Li-on batteries leaving the navigator in the car in the sun will shorten the battery life. |

update
Charged the unit overnight using main charger, approximately 12 hours and switched the unit on. The new battery lasted 8 hours with screen brightnest on highest settings. Given that a new battery needs 3 to 5 full charge cycles to form and achieve full capacity, the results are more than satisfactory.
I am happy so far with the battery. |

Kris, Is there enough physical room for two batteries to fit in the unit? If I wired them parallel, then I should get even longer run time?
Thanks for the info on where to purchase a new battery.

No, there is not enough room to fit a second battery.
Also, I am not sure if you can simply put two batteries in parallel. There might be a mismatch in internal impedance. But than again I am just speculating.
The battery technology advances very quickly so maybe in 1 - 2 years time we will get much higher capacities.

Thanks guys. I learned a lot on this board, so this "instruction" is the least I can do to repay the debt....
I hope it will help at least some of you. My two C320 I just replaced batteries in are doing great! |

| FYI All-Battery is out of stock of the 2400maH version. However batteryspace.com has them in-stock with tabs for the same price. I'm ordering mine right now because my battery died last night. Coincidentally 1 week after installing v8 :( |

just installed a new battery in my C340 and it seems to be working fine. still charging but I powered it up to make sure it was hooked up correctly and I found some satellites (after a few moments of worry that I had busted the antenna wires) and now it is charing for the night. Now I just have to dispose of the old battery properly.
thanks Kris. |

Kris, I wonder if you could include the tool list in the instructions. I'd have a heatsink clamp in there for safety's sake. If you solder quickly, you won't heat the cell. But if someone with much less soldering experience heated up the cell, it could explode.
And the heatshrink procedure needs care for the same reason.
When you disassemble, you should take note of how the GPS antenna slots into the unit. When I put mine back together, I tried a few orientations before I got it right.
Otherwise, an excellent guide (that could have saved me a bunch of money if I had read it when you first wrote it!) |

Do not know about Garmin.
Did both of my C320. Cost - apprx. $26 for two batteries with shipping and $1.50 for heatshrink. Worked out $14.50 per unit. And not shiiping to Garmin, being without th eunit for a week or so. I am happy. |

| Kris, the math on that sounds like a no brainer. It probably would have cost $14.50 just to ship the unit to Garmin, after you consider packaging, postage and insurance. |

| Well, figure again. The price is $32.50 not including shipping. I would suggest building the pack and tabs yourself. Also a no brainer. |
