Battery

[vt_maverick]

I have the watercraft/marine version "Battery Buddy" in my ski-boat. It has saved my bacon on countless occasions, and you definately don't want to be out on the open water with a dead battery!!! Most vehicles have things that always draw power; namely the clock on the stereo is the biggest culprit. The "Battery Buddy" is best for vehicles that are operated infrequently (like a boat); situations where it may be hard to get an actual jump from another vehicle (like a boat), or isolated locations such as a boat marina without a nearby electrical outlet (like a boat).

Or when you're say, out on a deserted beach in a national park, miles away from the nearest car, gas station, etc., and the minimum tow fee is $250.

Well, that is always my fear. I am building up my Trooper to be my hard-core expedition vehicle. After I am done, she is going to be pretty stout. The last thing I want is to get stranded 60 miles from the nearest paved road because of a dead battery. I guess I should always park near a hill so I can do a push start if I get stuck.

VT,

Looks like they've discontinued the 'battery buddy' so that they can introduce the 'battery brain' for more $$$ (but still less than $70 so that's not too bad).

The only experience I've had with them was when we installed some surveillance equipment on some Suburbans for the Boarder Patrol years ago. We didn't want them to use the equipment for hours on end without the engine running and then not be able to start the Burb for the final chase.

you should invest in one of those jumper boxes (im not sure what they are called but they store enough charge to jump a vehicle and are relatively small) if your really planning on using the trooper for long expeditions like that.

$29.95 at Pepboys but you needed to keep it charged as well. I do not see why you could not create a one way circuit that would allow a running motor to charge up a battery. Then have a switch that you could hit that if your car would not start would reverse the flow so the always charged battery could then jump the car.

sure, but then you would need a very large diode/very expensive battery isolator

same idea that they use for high end car audio, 2 batteries. but they dont cross signals, otherwise they would drain each other.

That's my major problem with the chargers, I'm too forgetful to make sure it's charged all the time. The battery brain/buddy isn't a replacement for a charger, but it should at least help to avoid the drain situation, which in my experience is what caused all of my battery flatlines.

Want to eventually have both, but chargers can be big $$$ if you want a really good one.

There is no button to push on the battery buddy. It has a solenoid that disconnects the battery somewhere around 13V terminal voltage. If you push the brake pedal or flash the brights, it reconnects the battery. No wiring required, just connect it in series with the battery's positive cable. For those with lots of accessories, they all have some small amount of leakage current, amps, monitors, GPS and so on. My expy sits for 5-6 days at a time, so it needs a battery buddy. But as said before, having a dead battery in BFE National Park would not be a good thing. It also could save your battery's life. Running a lead-acid battery to dead reduces its life dramatically.
I will break down the benefits of one battery vs another when I get home from work(I teach all this stuff at school, so I can make it understandable.)

I told ya it was years ago since I had any experience with a battery buddy. Back in the day when cars had wooden wheels ... ya had to pop the hood & push a button.

more than 50%....
