Does it make any difference to the battery if it is always used plugged in to the vehicle or should you use it stand alone sometimes?
Lithium Ion's have no such needs, and have no memory. Use it as you wish. However, full drains and then recharges are good for the first few uses for battery life.
can be found here because it has been talked about many times before. so the link is chocked full of information:
However never ever discharge a Lithium Ion battery completely, if you do you will damage the cell. You also never ever want to operate any device that has a totally dead battery that you just plugged into a charger this will damage it beyond use.
Garmin's will turn off before the battery goes below 5% so you shouldn't have to worry about that, but other devices my not.
However never ever discharge a Lithium Ion battery completely...
Bob, that's impossible, generally speaking. Lithium Ion bats have circuits designed to prevent this from happening by necessity.
So, there is no worry about this.
Garmin manuals state that to calibrate the battery gauge, “Allow the unit to fully discharge and then fully charge it without interrupting the charge cycle.”
I do that when I get a new unit, and then periodically during the life of the battery.
As to leaving the unit “plugged into the vehicle” note that Garmin advises to not do that because of the heat from sunshine that the battery in the unit may be exposed to.
My current GPS (765T) and all previous ones have either been connected to power either via a charger or USB always and have never had an issue with them or their batteries.
How long does the battery last with the GPS not plugged in and the GPS off? I assume there's some amount of current drain.
A lithium-ion battery provides 300-500 discharge/charge cycles.
Aging of lithium-ion is an issue that is often ignored. A lithium-ion battery in use typically lasts between 2-3 years.
Keep the lithium-ion battery cool. For prolonged storage, keep the battery at a 40% charge level.
* Avoid frequent full discharges because this puts additional strain on the battery................

Here is a good usage guide on Li-ion battery..

Thanks for the link I will keep it in mind if my battery ever wears out.
$45 plus God knows how much shipping they charge is wayy too much.that's %50 of the price of my GPS.
get one from amazon or even ebay.
...ore here. Note that I've not bought from them but have heard good reports:
Thanks for all the info,the battery replacement on another tread is great,always great info from everyone.
Google search found buy.com had Nuvi 300 series batteries for $17 with free shipping.
This is from Batteryship.com website.
The Garmin Nuvi 750 Battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible.
Thanks for the info-I am not to the point yet of needing to replace my battery, but I have noticed it doesn't hold a charge as well as it used to. 17 bucks is a better deal than buying a new GPS. My 350 might be old, but it still works fine. Now if only there were a way to use custom POI databases like the RLC with Google Maps I'd dump my GPS entirely.
for new batter mine also does not hold charge!
The PDA place wants $45 for an 885 battery, plus shipping. Batteryship is $27.95 with free shipping.
