c340 and battery

 

Unfortunately, my wife left my c340 "on" for about 6 hours while she was at work.

It was not plugged into the car-charger, and now the unit appears "dead." Even when plugged into the charger, the USB cable on my pc, or in the car with the car charger cable, the GPS is not coming on.

It is only about 6 months old, and lightly used. I've read the link to the process of replacing the battery, and think I can do it. But before I do, is there any possibility that the unit will come back to life?

I thought I read in a thread somewhere here (months ago) that it might. But that was months ago, and I can't find the thread, if it even exists. How long should I try charging with the charger before giving up, or is there something else to do?

Any suggestions, or should I just replace the battery?

Thanks!

Li-Ion batteries have a threshold voltage below which they will not recharge. The battery should shut itself down before it reaches this level. In the worst case, you have a warranty issue. That aside, the battery might well recover slightly (enough to creep above the threshold) if you just let it sit overnight. Periodically try to charge them via USB, not the 12v car charger or AC charger.

When you reach the point of opening the unit up, it's worthwhile disconnecting and reconnecting the battery. (I recently overcame a charging fault on my C510, by doing that).

Let it charge via USB

Charge the C340 via USB for a couple of hours and then do a RESET of the device. Look in the user guide to pull out the bezel in fron for the RESET button. My Dad's unit exhibited the same symptoms and we got it working again.

This fixed it

Apparently when it got very low on battery power the c340 appeared dead, no visible reaction to the charger or the on/off button.

However, it did recharge, and when I used the reset button, all was back to normal.

Good Tip

Need to remember this should my C340 ever run out of juice.
