If you file a complaint with the Kansas BBB, Garmin will repair your unit at no charge. I have done this with two C320 units whose batteries each failed at about 18 months. |

I've read quite a bit of this thread and have found some of the information very useful; however, I have replaced the battery in my C330 with no change in result.
First, I reused the protection circuit and simply soldered the new battery to the existing tabs and left the unit connected to a 13.5v power source for about ten hours. I got no change in result so I removed the protection circuit and soldered the red wire to the positive tab and the black to the negative and simply tucked away the green. Still, no change.
I now have the unit laid open on my test bench and it seems the red-to-black voltage differential is only about 2.4v--certainly, not enough to charge the battery.
Voltage differentials between red-to-green and black-to-green are both in the millivolt range.
So I have, for now, removed the battery alltogether as the unit works as well without it.
It appears to me the charging circuitry has gone kaput. Does anyone here have any ideas for me?

| How do you open the garmin C330? I can't get the faceplate off? |

Hello all!
I noticed my garmin c330 is not holding it's charge any longer. So, I searched google and found this site. Anyways, Kris2005, you only have two wires leading to your battery where I have three wires leading to my battery(green, black, and red). What's up with the green wire? Is that wire for charging purposes? When I decide to buy a new battery will I still use this green wire or just set it to the side and only use the red and black? |

So, what's the consensus on the battery for a dead C340? Mine is laying here apart waiting for an answer to the 3 lead (red, black & green) battery with the small circuit strip attached along the length of it (about an inch long). Will a 2 lead battery work or will it potentially blow-up without the green wire and circuit "board" attached.
The dead battery has a "circuit board" strip (for lack of a better term) glued to it with metal leads going to both ends of the battery. At the end of this strip are 3 soldered wires.
Which battery is a suitable replacement for this one? If I can get a $20 battery I'll fix this C340 and use it in one of my cars as a spare ( I also have a Nuvi 350 which I like except for the lack of an external volume control - the reason why I want to keep this C340 alive ).
Thanks for the help.

In regard to the consensus - replacing the battery is a doable project. I successfully did everything wrong and everything turned out fine anyways. If I can make a mess and have it work I am confident that anyone can as well. (make a mess I mean) I used the information here to order the closest thing to a correct battery I could find and then took my Garmin 340 apart after reading the first page of this thread. I figured why read any farther? I like being surprised how something will turn out. So when I was confronted with the surprise third wire it was an especially memorable moment. I then did the logical thing - guessed. I tucked away the green wire and pretended it did not exist. Then soldered the other two wires. The soldering really was easy so I cannot say I screwed everything up. Well I put it all together and it worked great - for about a week. Then it did not work at all. Apparently that third wire is important after all. So I disassembled the unit (with nothing to lose at this point) and contemplated my options. Luckily I kept the old battery with the circuit board attached . I pried the circuit board off the old battery. I did this with no care whatsoever. (just being honest) I next used the skills learned watching several episodes of McGuyver to solder the circuit board to the new battery, and the battery to the Garmin unit. I think I melted a few to many parts but no-one noticed. I next used black electrical tape to cover up the mess I made. (I believe a surgeon is trained to say "suction!" when they make a mess like this) Having no assistant to blame I crammed everything back together, said a short prayer and plugged it back in. Much to my surprise It works great. Battery life is better than every and the unit runs like a charm. I need to keep a fire extinguisher nearby in case the sparking gets too extreme, but that is only a concern in dry weather conditions.
I am totally impressed and surprised how well my carefully planned and executed plan came together. You can't even tell by looking at the unit the near disaster I had on my hands. So in summary If I can do it, you can do it. Good luck!

Joe,
Thanks for the tongue-in-cheek reply. What you wound-up with is what I plan on doing - take the old "circuit board assembly" off of the old battery by popping (or soldering) it off at the ends of the old battery. I should then have a long skinny metal strip with a circuit board attached to it. Then I plan to solder the ends of this metal strip right back onto the new battery at its ends - hoping I get the +/- right. It should look like the old set-up when finished. I think I'll do the black tape thing too instead of the shrink wrap.
Wish me luck. Got a spare fire extinguisher?
Tony
PS..I wound-up buying a battery WITH the "protection" built into it.
Perhaps it comes with a condom. I'll let ya know what happens. Is this the kind of battery you got also? Mine was w/o the tabs on the ends. Not sure that matters for the soldering job.
Update: I had an electronic technician at work look inside my C340. He charged the battery and told me the "main" board inside was fried. The battery is fine. So now, I have a battery on order for a dead C340. Anyone know where I can get replacement parts for the INSIDE of the C340? I'd like to fix it and keep it - but I'll need the main board that houses the LCD display. I know, I know, cheaper to buy a refurb one. But........any ideas? |

| battery arrived. spliced wires with white and green together- red to red- black to black. powered up just fine and taking charge. much easier to solder wires together than trying to solder to battery. |

The little circuit board mentioned in the forum is likely the PCB, (printed circuit board), used for over charging protection, soldered to one end of the battery. Garmin charges repair rates ranging from $125 for a c-320 to $200 for a c-550, plus shipping, of course.

Great job, Kris. |

Kris,
Excellent information. I have an older c320 with the orignal two-lead red/black battery that I suspect is dead. I ordered a 3.7V 2200 mAh C320-compatible battery from Megacpacity that, unlike the site display pic showing only a red and black lead, arrived yesterday with the red/black/green wire setup used in some other C3XX configurations. While I haven't taken a peek inside the heat shrink or cut anything else to void the warranty, there appears to be a small rectangular PCB on the side connected to the battery tabs. Can this three-lead battery be used, splicing only the red and black wires and tucking the green from the battery aside, or should I just return the battery and find a more "apples to apples" alternative? Appreciate any insight--other than the toasted battery, this has been a great unit. |
