[QUOTE] What is the amp hour rating for your jeep battery? That is what will determine how long a battery will last under a KOL. RC is based off a 20A draw that normally does not occur in a vehicle unless somebody put the vehicle in ACC mode and cranked up the climate fans
====
Amp hours is directly proportional to reserve capacity (RC)times(0.4167)=AH
To be technical
Multiply the reserve capacity by 60 to convert it to seconds. For example, if a battery offers a 100-minute capacity: 100 x 60 = 6,000 seconds.
Multiply this length of time by 25, which is the battery's amperage. Example: 6,000 x 25 = 150,000. This is the number of coulombs of charge in the battery.
Divide this answer by 3,600, which is the number of coulombs in an amp-hour. Example: 150,000 / 3,600 = 41.67. This is the number of amp-hours in the battery.
Odyssey 65 pc1750, RC=145minAH =145*60*25/3600=60.42
Per Odyssey specs 74Ah @20 hr rate, 65Ah @ 10hr rate
BAGM48H6-760AH=120*60*25/3600=50

Will the Forscan lite allow me to reset the battery to a different cca? Or do I have to use the full size version?

There are two suppliers to Ford OEM NA for H6 AGM batteries, Clarios (JCI) and East Penn. On the F150 it is Clarios. However, the Motorcraft service H6 AGM battery regardless of OEM is Clarios (different plant from their OEM plant also).

[QUOTE=PaulWil;6527966]Ford OEM H6 AGM from Clarios has a 70ah rate and a specified Reserve Capacity of 120min. I copied the specification area of the battery drawing that is loaded into Ford's database. To be more technical the conversion you offered does not include Peukert's findings for discharge rate. His findings found capacity decreases as the rate of discharge increases. Thefore, for Automotive batteries Ah is tested with a constant current 1/20th of it's rated capacity (i.e., 70Ah for OEM battery), 70/20 = 3.5amps. Reason at this level as it mimics closer discharge rates a vehicle will see. Discharging at a lower value than 20 or 25 amps, Ah increases dramatically. That is why I asked.


However, the formula you have shown will work for comparing batteries on store shelves on service batteries just not for OEM batteries. To prove that you are right, here is the Motorcraft H6 AGM service battery



I was just curios if you knew the Jeep OEM Ah specs.

Thanks brother. Just took a closer look at both batteries, and the Walmart one says 'Clarios', which confirms it's made by JCI, by your post above. The Ford one says 'Distr. PAR', instead of Clarios. But they're identical, so it also has to be made by JCI.

PAR is the French translation for Distr. All current Ford NA OEM batteries have wording on them in English and French so vehicles can be exported into Canada without any export sticker. When Ford exports vehicles to most other countries, Ford needs to cover the battery to meet the particular homologation requirements.

elptxjc

Okay. Thanks. So no word who makes the Ford battery then, but it has to be Clarios/JCI, since they're identical to the EverStart (Walmart) one. The other large manufacturer is Interstate, but it's hard to know who makes the OEMs since there's no wording.

PaulWil

The internals of any specific battery made by JCI (and most other battery manufacturers) is dependent on the marketing of company paying for the product. Walmart specifically wants a cost conscious battery so they get one that has less quality internally. For example recycled lead is much cheaper than pure lead. The fabric between the plates may even be different compared to the JCI top of the line version. This sort of tailoring of products has been going on for many years. The result is who makes the battery has little significance. The important thing is to look at the battery specs and warrantee and try to decide on the data. Independent battery testers can provide meaningful data. Find the testers with a Google search. like "who makes the best group xx batteries"

This^^ Ford issues the specs to make the battery. Sears never made those Kenmore appliances, Whirlpool made them for Sears. But a Kenmore appliance was usually better than a Whirlpool because Sears specd higher quality components. Just because the company that makes Wal-Mart batteries also makes Motorcraft batteries doesn't mean their internals are exactly the same.

Read post #53 where I say Clarios (who bought the battery business from JCI) makes the H6 AGM for the F150, and the H7 AGM for that matter.

Our local WalMart has apparently been on allocation from the battery supplier. They were almost out of units last week. A delivery was made finally and it was obvious batteries are being allocated. They only got one of the 760 H6 Platinum AGM's(5 yr free replacement) and it was gone within a couple days. Limited numbers of the 3 classes of type 65's also.
