Do any of you have a picture of the external power receptacle on a 172N or other model? Where is it located? I have to admit I've never seen mine and wonder if it was a factory option or something.

Here it is on my '78 172N, along with the sketch from the service manual. The manual says it was "offered as optional equipment." Mine may have been an aftermarket addition; the access door in the cowling looks different from the one in the Cessna manual.

I'm starting to think I just don't have one. Time to check the original config list. Thanks for the photo and drawing! I could not have asked for a better reply.

If I want one I'll have to look at having one installed this year during my annual. Pretty hard to "jump" without that receptacle.

Just spend the money on a battery minder, or a good battery and fly often. A good battery should hold its charge for at least 2 months and still start. Check that you don't have a clock wired onto the battery. Don

And where do you attach a battery minder?

In my case, I have a pigtail attached to my battery that I tie-wrapped to the engine mount just inside the battery access door on the left side of my cowling. I DID check with my AI before doing so, and had him inspect it after my install. I simply open the access door, remove the caps on the pigtail, and plug my Battery Minder in. It sets on a cart beside my plane in the hangar. Other AIs and A&Ps have seen it and never commented.

I am also aware that other model 172's do not have the large door on the left side of the cowling. I have no advice except to talk to the AI who will do your annual and ask for his opinion.

I don't have a battery problem but I do need to run my avionics for an extended period of time now and again for training and or configuration. A battery minder would be a good idea to keep the battery charged after an extended period with the master switch on.

My annual is coming up and I'll get my A&P to set this up. Thanks Don!

hooking to the pigtail is the easy way to attach a battery minder. I also have them on my motorcyles, too. Seems to work just fine, as it is easier than hooking up to the terminals each time you want to put on the battery monder.

Any issues with battery minder and wet cell batteries? I know when hard charging you want to allow any H2 to escape... For those using the minders, do you have sealed cells only, or does the slow trickle not generate enough hydrogen to worry about?

I know others will disagree, but a good battery in a sound plane should go 4 weeks no support and start the engine, then fully charge. I don't use a trickle charger IF I have gone a month as during winter and haven't flown I use a solar panel for 48 hrs before flying. Otherwise I use nothing to charge my battery. Battery minders cost $$ and can over charge if you dont' have the correct one.

I have a Concorde RG-25XC with a Batteryminder made for that battery.
