My garmin nuvi 2555 says battery is low when it is plugged into the vehicle. Also turns on and off in the middle of the directions
If the unit keeps displaying a pop up window saying that it will be shutting down with a count down timer then the problem is a loose USB port that keeps interrupting power to the unit. The reason why you receive a battery low warning is because the battery doesn't have a chance to charge because of the intermittent USB port. We see this problem all of the time on the Nuvi 11xx, 12xx, 13xx, 14,, and 25xx. We've repaired hundreds. Please see this link on why the problem happens and how we repair this problem so that it won't happen again.

Sounds like you both have a battery problem. I experienced a similar problem when trying to charge via the USB-cable connected to my computer.
Ended up buying an original charger (expensive) and the charging went smooth.
The car charger should in any case work fine, so probably your battery is not very healthy.
Try holding your finger on the battery symbol for about 10 sec. The unit will then switch to a technical page. There you can observe the battery and charging voltage. When I plug in my computer USB-cable, I read around 4,4V and that is not sufficient for charging my battery.
When connected to the original charger, this voltage rises to about 5V which gives a nice charge. When unplugging charger, the unit displays the battery capacity. If the charging voltage is OK, but battery capacity drops quickly after you unplug charger cable, the battery is probably bad. (Of course you have to charge is for some time) I think around 4V battery voltage give 100% capacity. 3,9V gives about 90% capacity.
This will not solve your problem, but can give you an idea about what is wrong.
Good luck.

Have you tried doing a hard reset,try using the reset button on the bottom of the gps under the serial label.Or try holding the turn off button for about 10 seconds,good luck.

folks, the garmins have an on-board battery that needs to be powered up (at least occasionally) via the usb port - like from your computer. just using the dc car power cord does nothing for this battery. i've had this exact same problem on both my 760 and 780 nuvi units. fixed it using the usb charge. seems to run down differently for all the various nuvi models. my regular charge will hold for 7 hours on my old 660, my 760 and 780 work about 5 hours. my 'power up' failed on the 660 after 10 months with no internal battery charge, but the 7xx models only took about 5-6 months to 'fail.' hope this helps. jack b :-) in midland, tx usa
SOURCE: my garmin won't turn on. I have tried the plug in
it does have an internal battery, but that normally wont prevent it
from turning on unless the battery is defective.
plug it in to the usb cable on your computer for a while (normally it will start right up) then slide to power switch to the on position for about ten seconds.
if that fails, press and hold the lower right corner of the screen and then slide the power switch to the on position while holding the lower right corner of the screen and follow the directions once it starts
i can give you something else to try before you go and spend money on a battery...a battery should be the last thing to do, even though it will more often then not fix the problem thats tempory..
if it turns out you think you need a battery, i will point you to one with instructions on how to change it.
