battery replacement

battery replacement

The battery in the 150 looks like it has to be replaced it's a "G25".  It looks like a riding lawn mower battery.  Does it have to be replaced with an aviation battery, or will any comparable battery be ok?

Re: battery replacement

Must have STC.  Use the Gill.  You cannot use whatever you want in aircraft.

Re: battery replacement

I know this will sound dumb, and I am even dumber, but what is STC, and what is "the gill"?

Re: battery replacement

STC  Suplimental Type Certificate.  Gill is brand of aviation batteries that work well.

Will:

There are a few battery manufacturers out there that have FAA-PMA batteries for a Cessna 150.  Your replacement battery does not necessarily have to be STC'd.  If you buy a PMA'd battery check the manufacturers eligibility list to verify it can be installed on your model.

Re: battery replacement

Can anyone tell me what the cold cranking amps rating is on the Gill G25?
I want to check the battery to see if it is good or bad, but without the cca rating, it's a crap shoot.

Re: battery replacement

Never mind, I just found that it is 250 cca.  This battery held up at a 300 cca test, only dropping to 9.60 volts, then recovering to +12 volts, so I think it is good.

Re: battery replacement

I stopped offering Gill batteries (unless the owner absolutely insisted)
Concorde makes a sealed lead acid battery for the 150.

The sealed battery is maintenance free (no checking water levels),will save your battery box from corrosion, and will give you more energy to the starter.

Sure, they may require an STC (Supplemental Type Certificate) and cost a whopping $25 more, but the benefits definitely outweigh the initial costs.

Re: battery replacement

Thanks to everyone, but it looks like the battery is still good.  For some reason, it lost some of the charge, showing only 11.3 volts, and when I put a load to it, it dropped to 3 volts.
But, after a night on the charger, I brought it to an Advance auto supply store, and they tested it at 300 cca, and it only went down to 9.6 volts, and recovered to over 12 volts.

Re: battery replacement

Have to agree with RH.......I don't stock or sell Gill batteries. Concordes are the only ones I install. Much cleaner, more power for cranking, less heat during recharge and handles cold soaking better....which is REALLY important up in SE Canada where RH lives.

Re: battery replacement

So what do I have to do to replace my Gill with a Concorde?

Re: battery replacement

Will,

If the battery will not hold it's voltage, then it has to draw more current to get the same power.  This increases the current through the starter and may impact the starter life. 

I fear I just run into this problem as of late due too much cold cranking of the engine recently when the plugs had condensation on them.  I should have used a preheater.  It was 28 degrees in DE and had a lot of rain during the previous few days.  My plane's stuck at MYR (Myrtle Beach, SC) right now waiting for Monday morning to roll around and probably will need a new starter.  I may end up replacing the battery in the my C-172.  Looks like the Concorde battery is a good choice.

Re: battery replacement

you can get the Concorde from Wilco  in Wichita Kansas. Also recommend EZ pan heater or such and use any time temperature is below 32 degree F. Operated fleet for 15 years and this was our policy.

Re: battery replacement

Concords are service free but a bad choice if you dont fly much.  If you don't fly at least weekly get the Gill.  If you do fly frequently get the Concord.  Note:  Concord would not fit correctly in the battery box of my 182 - had to use a Gill which are very good batteries.

Re: battery replacement

Most parts houses carry the Concorde batteries.

I'd pick someone near by as 25lbs is heavy to ship.
The good news is Concorde batteries do *not* fall under hazardous materials qualifications for shipment (ground or air).  The battery acid  needed to fill Gill batteries *does* qualify as hazardous materiuals.

Chris, I'm curious.
Why you feel Concorde batteries need more excercise than Gills?

Best regards,
RH

Re: battery replacement

Regarding the shipping of batteries.  I've had both Concorde and Gill shipped to be from Chief Aircraft (Oregon State)  Both batteries came in a box that contained the battery acid in a seperate container.  I havent been charged extra for hazardous materials by chief.  They were shipped UPS ground.  I think Chief's website states whether or not an extra charge applies to particular batteries.  I'm sure there IS an extra charge if it's shipped by air...for the faster service AND hazardous material.  Shipping charges used to be included on the batteries...It's been about 4years now...I'll probably be finding out
if things have changed much in the not too distant future...
It definately does pay to shop around, if you can.

Re: battery replacement

Apparently sealed batteries do not hold a charge as long or as well.  When I bought my battery last xmas, this was explained to me by a salesman at Falcon Aircraft Supply.  I opted for the Concord because I fly regularly but I had to bring it back b/c it didn't fit right in the battery box.
