Gryphon and battery drainage..

Uncle · #1 Wed, February 16th, 2011, 04:30 PM

Hey guys, just a totally satisfied Gryphon user here! I have a question. On occasion, i go out of town for 2 weeks at a time and leave my truck parked at the airport. The last time i came home, it was in the winter, so it was cold here, for Knoxville anyway. When i got to my truck, the battery to the truck was dead. My remote would not unlock the doors, nothing. I had to get a jump start.I double checked my interior lights, made sure i had not switched them on in the pre-dawn darkeness my flights always seem to leave. My headlights were not on, nothing i could find explainded my dead battery. I took it the next day and had the alternator checked and battery checked, no problems. Does the Gryhon continuously pull power from the truck even while it is switched off? Should i unplug the module from the OBD2 port if i leave the truck sitting for more than a week?

Thanks guys!

The gryphon pulls a very small amount of current but it wouldn't hurt to unplug it.

Both your truck and the Gryphon have a parasitic draw....
Battery tenders both plug in and solar are great ways to combat this....

I've read on other sites about the Evolution CS having a parasitic draw. I am planning to order a Gryphon CS for a 7.3 that sits for weeks at a time so this is of interest to me. I have a solar powered charger that plugs into the cigarette lighter power port. Would there be any reason I shouldn't use it on a 2003 7.3 with a Gryphon to keep the batteries charged?

You should be fine....

Nope, most of them don't even have the wattage to overcharge a single small battery. I have one that is called a "battery maintainer" and it says it only puts out 1.8 watts. I have yet to see more than half of that when I tested the wattage so I'm not worried. When you start getting up around 5+ watt chargers you want to look for ways to protect from overcharging. Many of them have have that built in but you always want to check.

I'm still testing because got mine a few weeks ago (whenever it actually snowed that 5 hours in Texas

) to help keep the battery cranking strong.
