Battery does not hold charge. how to replace?

doesnt hold a charge is not a good battery --have battery and alternator tested

Leave it on charge on the computer and if it does not still come on, then you try to fix it in another gps device and try to charge it on there, if it still does not hold a charge, then it means you will have to replace the battery, because the cells are weak and cannot hold a charge.

the alternator might be gone in it, either that or the battery is too old and the core inside it isnt doing its job, before spending money, if you can, try use another battery from another car or a friends car and try run it and see if it holds the charge, if its draining still and not charging then its your alternator, it will need to be replaced or rebuilt. only two things that will cause the battery to not hold charge.

Yes, most likely you may need to replace the battery. Try to get a different cell capacity this time (I do not know if you currently have a 6 cell or 9 cell battery). Once it's not keeping a charge it most likely has a problem.
Hope this helps...

hi dave_hanc93

you say its not holding a charge, but is it charging?

plug the charger in and make sure the light is on on the charger, then on the map screen, tap the screen where the satellites are. on that screen on the top right is the charge indicator. is it green and moving from left to right? if not, then its not charging.

try hooking it up to the home dock to your computer and check and see if its charging on the home dock.

let me know how you make out.

Try updating firmare and software so that your computer will recognize it and maybe charge battery

THE BATTERY IS ONLY FOR STAR THE CAR. WEND THE THE CAR IS RUNIG ALTENATOR IS CHARGING THE BATTERY FOR NEX TIME YOU NEED TO STAR THE CAR . CHECK CHARGE ON THE ALTENATOR . IF ALTENOTOR NO CHARGING REPLACE.

Try making sure that the battery is working properley, if not then replace the battery by going to a Batteries Plus store near you.

Common issue. Steps to troubleshoot/solve:
1. Pull off face, press reset tab.
2. If unit wont turn on or if turns off immediately, connect to home computer using mini usb on side of gps (any usb cord that fits will do). This will charge the internal gps battery, which is discharged.
3. You will not be able to see the gps charge indicator while the usb cord is plugged into the unit. To check charge level, disconnect it, turn it on, and note the large "battery" icon.
4 Do you have a dead internal battery? If the gps holds a charge from your computer usb port, you don't.
5. If you have a dead battery, Google DIY replacement. With some soldering it can done for $15 total.
6. If you don't have a dead battery, the issue is charging from the cigarette lighter socket. Your car socket may have blown a fuse (check car manual). Your charger unit may have blown a fuse (unscrew the tip, check fuse inside). Also, some car sockets don't work when the ignition is off. Test yours.
7. There is a good chance the connection of the charger wire to the gps cradle is the problem. Fiddle with that. Replacement cradles are available for the c340 at about $25.
8. If your unit is not charging from the cradle/socket, buy a 12v usb cord. Plug into socket and into usb port of the gps. This is a workaround or alternative to buying a new cradle.
9. IMPORTANT: observe the "battery" icon while driving, esp. if you have doubts about charging. Basically, if you can see the icon, you're not connected to an outside (car or computer) power source. That is, if you can see the battery-charge indication, it means your battery is currently discharging and unless you get another power source to work it will be dead in a few hours.
