mgbinspect Posted December 23, 2009 Report Share Posted December 23, 2009 Thanks to the time of year and a foot of snow, I haven't done an inspection since last Friday morning. And, as I showered and mentally prepared for my 2:00 PM inspection the thought arises - my truck's been sitting in the driveway for four days under a blanket of snow with the GPS plugged in, on and charging. [:-sour] I'm about to deal with a dead battery... RATS! [:-weepn] Don't forget to unplug your GPS for extended down times! Quote Link to comment Share on other sites More sharing options...

mgbinspect Posted December 23, 2009 Author Report Share Posted December 23, 2009 Yeah, I have AAA, But I won't need it. Just glad I thought of it with 5 hours to get up and running. Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted December 23, 2009 Report Share Posted December 23, 2009 Most plug in stuff draws less than 50mA. So every 20 hours = 1amp hr. Most car batteries are rated well over 100 amp hours and many are rated >135 amp hours. My points is, if your battery is dead after running your GPS for four days you need a new battery.

mgbinspect Posted December 23, 2009 Author Report Share Posted December 23, 2009 Fortunately, it struggled a bit but started. Last time I went to spend five days in FL with my folks (seven actual days downtime) it needed a jump. You're probably right, Chad. I should probably get it checked with the cold months ahead.

fqp25 Posted December 23, 2009 Report Share Posted December 23, 2009 A little drift; but I'm wondering how long does your GPS hold a charge. I had an inspection over 45 minutes away, and had it plugged in the whole way there. Then I unplugged the GPS but kept it on. By the time I hit the road it had been around three and half hours, and noticed that the GPS was off. I figured it went into a sleep mode or something, but when I turned it on it flashed low battery and turned itself off again. I've had it for over year and always kept it plugged in or turned it off when I stashed it away when I parked. I guess I just expected it to hold a charge for more than 3 and half hours. Is this the same for most brands? I have a Tom Tom. (I know it's not the best but I'm still content with it, might go with a Garmin once I recalibrate after the holidays) Frank Quote Link to comment Share on other sites More sharing options...
mgbinspect Posted December 23, 2009 Author Report Share Posted December 23, 2009 Between two vehicles and passing units down to my kids, I'm on GPS's five and six. They really don't go too far ON and unplugged, so what you're describing is typical to above average. Quote Link to comment Share on other sites More sharing options...
Mark P Posted December 23, 2009 Report Share Posted December 23, 2009 I would think it should last 2ish hours unpluged. I took mine to Sydney this summer and used it when I was just out walking around town it did pretty good. Quote Link to comment Share on other sites More sharing options...
Les Posted December 23, 2009 Report Share Posted December 23, 2009 I have noticed that many times after I l leave one of my folding maps open and unused for several hours they re-fold automatically. I also had a magnetic device that always pointed north. It was worthless anywhere on the south side of the state. I am at a stage (passage) in my life where I do not accept an appointment unless I have been there before or they send a driver. Remember door bell batteries? Ray-o-Vac, Everedy, Edison? You should never go places that require electronic devices to guide you! Quote Link to comment Share on other sites More sharing options...

Tom Raymond Posted December 23, 2009 Report Share Posted December 23, 2009 Gary, Don't burn your GPS, it's bad for the environment and won't stay lit long enough to keep you warm anyways. Tom Quote Link to comment Share on other sites More sharing options...
mgbinspect Posted December 23, 2009 Author Report Share Posted December 23, 2009 Les does have a point. There are times when I've been out in BF Egypt staring at the driveway to a large farm and my GPS is insisting that my destination is just the other side of this humongus property thinking their driveway is a highway. That always stinks. Quote Link to comment Share on other sites More sharing options...
Bain Posted December 23, 2009 Report Share Posted December 23, 2009 I was listening to NPR one day, and they were describing how a guy drove his car off a cliff, tumbled over several times, but miraculously survived. When asked what happened, the driver explained that there had been a heavy rain that limited visibility, so he was moving slowly and following the instructions of his GPS. The GPS told him to take a right turn, but no one had told the GPS that a certain bridge had been removed the previous year. Quote Link to comment Share on other sites More sharing options...
resqman Posted December 23, 2009 Report Share Posted December 23, 2009 I have two outlets in my vehicle, one that is hot all the time and one that is only hot when the car is running. I plug the GPS into the one that is ONLY hot when the car is running. Start the car, GPS turns on, 15-20 seconds later, I have a screen that accepts input. When turn car off, GPS signals it has lost power and will shutdown in 30 seconds unless I request otherwise. I purchased lifetime updates from Garmin. About once a quarter they send me an email that updated maps are available. Takes about 3 hours to download and update the GPS. Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted December 23, 2009 Report Share Posted December 23, 2009 If the GPS is plugged in to charge but it is not turned on, a good car battery will last a very long time. Once the GPS battery is full, the draw almost ceases. Add to that, the size of the GPS battery compared to the size of a car battery is no match. The car battery can fill many a GPS batteries and still have enough juice to get the engine started. The reserve power of the car battery will sustain it for a long time. How about how they suggest that you unplug your cell phone charger when you're not charging your phone? Isn't that a mis-leading suggestion? Am I correct in thinking that if the phone is not plugged in and charging, there is no draw? Quote Link to comment Share on other sites More sharing options...

As far as I understand it, AC power is still used whether or not the phone is plugged into the charger. With DC, I don't know. Quote Link to comment Share on other sites More sharing options...
Stephen D. Gazo Posted December 24, 2009 Report Share Posted December 24, 2009 GPS where the hell do you guys live. Seriously, I was watching Bear Grylls last night on TV. He started the second day of his treck complaining that he left his gps on overnight and now the batteries are dead.

mgbinspect Posted December 24, 2009 Author Report Share Posted December 24, 2009 Well, for what it's worth (and this is a little bit of drift), the tech at the T-mobile store was explaining that phones on AC chargers are "smart" and stop charging after the phone battery is fully charged. But, DC powered chargers apparently keep charging and can wear out your phone battery. His point had nothig to do with this discussion, bir apparently it's best to limit charging a phone in your car.

Erby Posted December 24, 2009 Report Share Posted December 24, 2009 I've got a power converter plugged in to the rear lighter in my van. Then a power strip plugged into the converter. Use it to have AC to charge my computer, gps, phone, camera batteries, rechargeable batteries, etc. One switch (on the power strip) shuts everything down. - Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted December 24, 2009 Report Share Posted December 24, 2009 One switch (on the power strip) shuts everything down. John, Anyone want to take a stab at why I've had more dead batteries in my trucks than I care to remember? Hint: I walk out to my truck and hear a screeching alarm sound [:-censore I carry jump start cables at all times, but am tempted to carry my battery charger as well. Asking agent's for jump starts is getting old. I always back into driveways just in case the need for a jump start arises. Quote Link to comment Share on other sites More sharing options...
