Battery Tender
« on: June 21, 2017, 01:25:52 am »
In the thread about buying new Gill batteries, I mentioned that I had just put in a battery tender, which is supposed to increase the life (hat tip to Adam, who gave me the idea). I also put in two new batteries at that time, about 18 months ago.

Before that, I was replacing them about every 18 months - 2 years.

So, 18 months in, at the 150 hour the batteries passed with 100%. Usually at this point they tell me they barely passed or just failed and I end up replacing them, either now or in 6 months. So to have them at 100% is really impressive.

So I think the battery tender is working out well.

Good info Don... I have been using one since they became digital about 8 or 10 years back and have had far fewer battery issues as well. But I also use cart (APU) starts as much as possible, so I was not really sure which was helping more. Before the digital units it was mechanical and a hassle every 18 to 24 hours adjusting it. Not sure which one you have, but some of the more complex digital tenders have a "refresh" cycle and that clears the plates of the calcium I think it is.
For me it has been money well spent.

Hi!!!!

What is the price of a battery tender? Does it need an STC or custom kit? Is it just plug and play???

Kind regards

Don,
That sounds great!
Would you mind, once again, sharing which tender you purchased? 

thanks,

Mine is a "Battery Minder." It's aircraft-grade. I believe it was installed as a "minor alteration" but I'd have to check.

I'm including some photos-- it just has a plug in the baggage compartment.

This is the unit that I have used for a few years.

It really is important that you use one that is designed specifically for aviation batteries. This is a good info article to review.

Incidentally, I almost never do GPU starts. I don't recall if I've ever done one with this airplane. Maybe once, at most.

At home, it's not practical as I don't have a GPU, or anyone to pull the plug if I did. On the road, I guess I could do them sometimes, but it just doesn't seem necessary. If it was really cold or something I might consider it, but that's about it.

Another year in, and the batteries yet again passed with flying colors. I think I've more than paid for my battery tender setup by now.

Me too Don.. I have not had a battery issue in over three years now.  The digital tenders are worth every penny

Speaking of batteries, at the last flyin the guys that fly all the freight in Commanders said they use a totally different battery now that is lighter and lasts forever with very little maintenance.  Does anyone know anything about what they're using?

Yes.  They installed mine a couple of years ago and I have had zero problems with it.  Two 12-volt batteries hooked together.  If I remember correctly, they told me the reasoning is replacement at an out location would be much easier than finding a 24-volt.  I haven't had to deal with that yet, though.

Did you have to get STC or anything to replace the 24 volt battery?  I'm not thinking it was concord that they were talking about.  I need to get in touch with them and get more specifics.  They kept raving about them at the flyin though.

I'm at four years now on the same batteries. I expect I'll probably have to replace them at the next annual, but still, huge improvement!
