    Skipper Batteries - Revisited

    I have had far better luck with Concorde batteries than with Gill, for the
    past five years or so. The reduced idle drain of the Concorde AGM (sealed,
    absorbent glass matt) helped it perform better than wet-cell batteries, in
    the Aviation Consumer tests.

    Subject: [musketeermail] Skipper Batteries - Revisited

    Musketeer Group,

    I thought I would share some of my battery woes.

    I purchased a Gill G-25S (Sealed) battery for my Skipper back in November.
    I've had the battery go dead on me 5 times since then. Every time I would
    remove it from the plane, take it home, and put it on a charger.

    I finally spoke with a technican from Gill today. He said that the sealed
    batteries are tempremental and would require a 'battery maintainer' plugged
    in after flying to keep it fully charged.

    Since I don't fly nearly enough to keep the battery charged, he recommended
    I go with the standard G-25 wet battery. He gave me a warentee number and
    told me where to exchange the old battery.

    I got the new G-25 from a local distributer. I have the shop at Hillsboro
    Airport putting in the acid and charging up the battery. It should be ready
    tomorrow. I'm hoping for better luck.

    My old Grumman had a Gill wet battery that one time sat for 2.5 months from
    the middle of November to early February. After all that time the engine
    started right up!

    I'll let you all know how the new battery works.

    I suspect that a Concorde rep might disagree with the Gil rep.

    BTW - can anyone shed light on whether an STC is required for the
    Concorde battery? I can get a Condorde RG-35AXC replacement for the
    G-35 about $135 - but the STC is only available from Wilco which
    sells their private labelled Concorde RG-35AXC for $237, but then
    provides the STC for free.

    Anyway - I was having issues and my 3 year old Gil G-35 was only
    charging to about 11.9V - but $50 at Northern Tool got me the
    Battery MINDer (recommended by several people on the BAC website)
    and after only 2 weeks it was charging to 13.8V again...so $50 well
    spent.

    Installation basis for Concorde battery in a Skipper?

    (I searched and searched, but couldn't find the answer...)
    My old Gill is going to be 6 this summer and although it works fine on the Battery Minder, I'm thinking of a preventative replacement. I'm interested in changing from the Gill G-25 to the Concorde RG-25.

    Concorde doesn't list this on their applicability guide (only their wet cell CB-25) and I can't find anyone with an STC to put the Concorde RG battery into the Skipper.

    Gill only lists their wet-cell G-25, not even the G-25S VRLA battery.

    If I want to put the concorde battery in, do I need a 337? Or since the battery is the same, standard size 25 can it simply be installed? I don't really understand the "PMA" term.. does it apply to the battery, or the application of the battery to the airframe?

    Thanks for any info, especially from IA types (Bob?)

    Hi my skipper does not start recently
    my CFI says just jump start it, but I do not want to risk it for future
    I am so ignorant but where do I go to restore the RG-25?
    Can I do the job myself or got to go mechanic ?
    Sorry I am still a student pilot and new owner
    Thanks!

    Finding threads that are 10, 14 years old and still applicable reinforces the value of these forum threads!!

    You can't restore a battery, well at least not easily. Best bet is to buy a new one. IIRC Aircraft Spruce has them with free shipping. Battery removal and replacement is not A&P territory, logbook entry by owner good enough unless your installation requires an STC.

    There has been a consensus in these forums that I have read that most of us favor the Concorde sealed batteries. I have had one for about 8 years now and do not use a maintainer. I have been getting concerned that maybe I should replace it, but read that Concorde says to replace them only on condition. So....until it fails to start the plane or shows some sort of low power sign, I am going to keep going with it. I bought mine from Wilco Aircraft Parts in Wichita, KS. If a person needs it, they provide the paperwork for free if you need it. (I think it is an STC.) Good people to work with. https://www.wilcoaircraftparts.com/. By the way, my old lead acid battery was corroding the belly skin just aft of the battery vent hole. Paint was pealing off. I don't worry about that anymore. We cleaned up that corrosion and painted it. Removed the vent and sealed the hole. No problem now.

    At least once a year (at annual) the battery “should” be load tested. Below a set level (of reserve capacity) it should be replaced. Waiting for it to fail is a false economy, as it places a greater strain on the rest of the electrical system.

    Eight years is about retirement age for a Concorde.

    I move mine down the line. Put a fresh battery in the plane and the old one goes to the lawnmower or the log splitter.

    Mine went 11 years until I bragged about in the forums and it failed next start. I'm Irish, I should know better. IDK if STC paperwork is required anymore, but even if it is, replacing a concorde with a concorde should be covered by the first STC.

    In my 40 years of owning aircraft, I've never had an A&P so much as offer to load test the battery. I don't know if any of the many A&P's I have had over that time have the tool to do it. I don't have the equipment and don't know how to do it. Sometimes we do what we have to do Mark. You might consider a detailed description of the tool, including make and model, that is used and how to do it in these forums.
