Tom , who always has a contrary opinion,
Only when bovine skitology is present.
Tom , who always has a contrary opinion,
Funny thing, I've been reading a new book I just got, it mentioned seaplane operators removing their batteries and taking them in for the night, as well as their oil.
A good freezing winter precaution is drilling some small holes in the top sides of your crank case breather tube incase it freezes up.
You also have the pour point of your oil. You'll ether know it, or see it when your oil congeals in your cooler and pressure spikes.
100W -4F
15/50 -43F
This is far colder then most here will fly in, but.. Even with a good preheat, split weight is a good call for winter.
The 15/50 is going to run through the engine easier, getting to all the parts needing lubrication better.

If you believe your battery needs to be warmed you might ought to lose the old flooded battery in favor of an AGM type. I've used a small Odyssey jet ski battery to start my 0-520 for 15 years and the battery has never been warmed and never needed charging including after all-winter storage. AGM batteries keep full charge for two years of inactivity in average temps so you can lose the battery maintainer, too. http://www.odysseybatteries.com/docs/US-ODY-TM-001_0411_000.pdf

1004. AIRCRAFT STORAGE BATTERY DESIGN AND INSTALLATION.
a. Lead Acid.
(1) Each aircraft storage battery, whether approved to a Technical Standards Order (TSO) or not, must be designed as required by regulation and installed as prescribed by the manufacturer.
1. PURPOSE. This advisory circular (AC) contains methods, techniques, and practices acceptable to the Administrator for the inspection and alteration on non-pressurized areas of civil aircraft of 12,500 lbs gross weight or less. This AC is for use by mechanics, repair stations, and other certificated entities. This data generally pertains to minor alterations; however, the alteration data herein may be used as approved data for major alterations when the AC chapter, page, and paragraph are listed in block 8 of FAA Form 337 when the user has determined that it is:
a. Appropriate to the product being altered,
b. Directly applicable to the alteration being made, and
c. Not contrary to manufacturer’s data.
AC43.13-2B chapter 10 discusses standard practices for installing and/or relocating aircraft batteries including lead-adid and nicad types. AGM batteries are lead-acid batteries but use Absorbed Glass Mat design as opposed to flooded cells. Here's an important excerpt from page 108 of the AC.
And for the nay-sayers out there who will argue the AC doesn't allow you to modify the battery or location, here's a quote of the opening paragraph of the document. The AC also talks about ski installations, shoulder harnesses, avionics, etc.

Not everyone will interpret all documents the same way. I'm okay with that. The FAA provides us with much more flexibility than many aircraft owners are aware of. If you prefer to ask permission for approved maintenance practices that are documented? Go for it. Or perhaps you may want to use the Odyssey SBS-J battery which is PMA'd. I've used both. I like the PC625 better.
And for the nay-sayers out there who will argue the AC doesn't allow you to modify the battery or location, here's a quote of the opening paragraph of the document. The AC also talks about ski installations, shoulder harnesses, avionics, etc.
7. ADMINISTRATIVE PROCESSING. Form 337 will be executed in duplicate with one signed copy given to the aircraft owner and one copy forwarded to the FAA within 48 hours after the airframe, aircraft engine, propeller, or appliance is installed on an aircraft and approved for return to service. FAA processing of the forms and their supporting data will depend on whether approved or unapproved data is used.
a. Approved Data. Complete the form as instructed in this AC, excluding item 3, and ensure that items 6 and 7 have been properly executed. Give a copy of the form to the aircraft owner/operator and send a duplicate copy to the FAA Aircraft Registration Branch within
48 hours after the airframe, aircraft engine, propeller, or appliance is installed on an aircraft and approved for return to service.
b. Unapproved Data. Complete the form as instructed in this AC, leaving items 6 and 7 blank. Both copies of the form and any supplemental data will be sent to the local FAA district office. When the FAA determines that the major repair or major alteration data complies with regulations and conforms to accepted industry practices, data approval will be recorded by entering an appropriate statement in item 3. Both forms and any supplemental data will be returned to the applicant who will then complete items 6 and 7. The applicant will give one of the completed forms to the aircraft owner/operator and submit the other completed form to the FAA Aircraft Registration Branch for inclusion in the aircraft records.
That quote can be found on page 6 of the linked AC regarding 337 forms.

Well, heres a quote from the FARs,
21.9 Replacement and modification articles.
(a) If a person knows, or should know, that a replacement or modification article is reasonably likely to be installed on a type-certificated product, the person may not produce that article unless it is—
(1) Produced under a type certificate;
(2) Produced under an FAA production approval;
(3) A standard part (such as a nut or bolt) manufactured in compliance with a government or established industry specification;
(4) A commercial part as defined in §21.1 of this part;
(5) Produced by an owner or operator for maintaining or altering that owner or operator's product; or
(6) Fabricated by an appropriately rated certificate holder with a quality system, and consumed in the repair or alteration of a product or article in accordance with part 43 of this chapter.
(b) Except as provided in paragraphs (a)(1) through (a)(2) of this section, a person who produces a replacement or modification article for sale may not represent that part as suitable for installation on a type-certificated product.
(c) Except as provided in paragraphs (a)(1) through (a)(2) of this section, a person may not sell or represent an article as suitable for installation on an aircraft type-certificated under §§21.25(a)(2) or 21.27 unless that article—
(1) Was declared surplus by the U.S. Armed Forces, and
(2) Was intended for use on that aircraft model by the U.S. Armed Forces.
The AC 43,13 can not be used when the aircraft is supported by manufacturers manuals.
Plus FAR 43-A (a)
(xii) Changes to the basic design of the fuel, oil, cooling, heating, cabin pressurization, electrical, hydraulic, de-icing, or exhaust systems.
If you believe changing the type of battery used isn't a major change to the production certificate, explain why all the Jell Cell batteries come with a STC to install them.
When you leave blocks 6&7 blank what are you asking for?
c. Signatures of Form 337.
(1) An FAA inspector’s signature in item 3 indicates approval of the data described in that section for use in accomplishing the work described in item 8 of the form. The statement of completeness in item 3 by an appropriately rated designee is a “certification of completeness” of required data. It is not a field approval or approval of data.
NOTE: Signatures in item 3 count as data approval or completeness of approved data only and do not indicate the approval for return to service for the work in item 8.
(2) A signature in item 6 is a certification by the person performing the work that the work complies with all applicable airworthiness requirements and FAA-approved data. The certification is only applicable to the work described in item 8 or attached sheets.
(3) A signature in item 7 by an FAA Flight Standards Inspector or Designee constitutes an authorized return to service. A signature is not an approval of data. Data approval procedures are performed in item 3 by an authorized individual and further defined in Order 8300.10 and AC 43-210. Other persons listed in item 7 are authorized to “approve for return to service” if the major repair or major alteration uses and conforms to FAA-approved data and is performed in compliance with part 43.
(4) If engineering assistance was requested, written Aircraft Certification Office concurrence (e.g., memo or e-mail) becomes an attachment to Form 337.
§43.9 Content, form, and disposition of maintenance, preventive maintenance, rebuilding, and alteration records (except inspections performed in accordance with part 91, part 125, §135.411(a)(1), and §135.419 of this chapter).
(a) Maintenance record entries. Except as provided in paragraphs (b) and (c) of this section, each person who maintains, performs preventive maintenance, rebuilds, or alters an aircraft, airframe, aircraft engine, propeller, appliance, or component part shall make an entry in the maintenance record of that equipment containing the following information:
(1) A description (or reference to data acceptable to the Administrator) of work performed.
(2) The date of completion of the work performed.
(3) The name of the person performing the work if other than the person specified in paragraph (a)(4) of this section.
(4) If the work performed on the aircraft, airframe, aircraft engine, propeller, appliance, or component part has been performed satisfactorily, the signature, certificate number, and kind of certificate held by the person approving the work. The signature constitutes the approval for return to service only for the work performed.
You would be wrong, other wise why would the aircraft battery manufacturers spend the money to gain STC authority?A would say a battery arguably falls under 21.9 (a)(3)
That only applies when using UNAPPROVED data, as is clearly stated in the document. Once the data has been reviewed and accepted...
I posted the appropriate chapter and verse regarding 337s. I can provide the info but interpreting it is up to the reader.

When you use an off the shelf tractor battery how would you prove you meet the owner produced part, when you had nothing to do with its production?
When you use a new era battery in place of a wet cell lead acid battery, you have made a major alteration to the production certificate the aircraft was produced under. Plus as an A&P how would you comply with FAR 43,13 ? How will you prove the tractor battery complies with any thing the administrator has approved?
Interesting....it's time to change my oil as it's now frigid and I had been using aeroshell 100w in my Continental O-300.
Someone (I believe Ron) commented that if I switched I'd see less oil burn. What oils do you recommend? There's a lot more available since the recommended oils were published in 1956.
Do I need to do a full oil change or can I just add in the new oil?
I have yet to do an oil change on her so I'm interested in learning how it goed
They meet an industry standard, they all do, it doesn't say FAA Approved/PMA/TSO or anything like that. I would assume that the rules are different if you operate 135.
Proving a product not intended to be used in Aviation meets the aviation standard is an unsurmountable task.
Just think how long it has taken Whelen to prove their LED landing lights are a drop in replacement for the GE incandescent bulbs. the money it required is now reflected in the price of the new LED light.
Trying to do that with a tractor battery off the shelf at Central Tractor Inc. would get stonewalled from Day one.
Using the Unapproved battery would be like substituting a AN standard bolt with a ACE hardware stove bolt. they do not meet the standard for production certified aircraft.
Perfect example of the task at hand....

(3) A standard part (such as a nut or bolt) manufactured in compliance with a government or established industry specification;
Where is "Aviation Specification" listed in that? Batteries are all built to established industry standards, and are easier to make and less safety critical than nuts and bolts.
And yes, the alternator/regulator are field approved.
It's called a Mil-spec, look it up. AN, MS, NAS. see 43,13
1004. AIRCRAFT STORAGE BATTERY DESIGN AND INSTALLATION.
a. Lead Acid.
(1) Each aircraft storage battery, whether approved to a Technical Standards Order (TSO) or not, must be designed as required by regulation and installed as prescribed by the manufacturer.
A quote from AC43.13-2B chapter 10
When the manufacturer gain certification publishes manuals to support the maintenance, and Illustrated parts catalogs for parts replacement, you can for get using the 43,13 as approved data for making any modifications on that make and model.
Here's a link to CFR 23.1353, the regulation regarding aircraft battery design and installation.
