Daves1940Buick56S Posted July 30, 2017 Share Posted July 30, 2017 I got mine from Batteries Plus. 3EH like the other numbers. Going into Year 4. Cheers, Dave Link to comment Share on other sites More sharing options...
MCHinson Posted July 31, 2017 Share Posted July 31, 2017 If there is a Tractor Supply near you, check out their batteries. I picked up a 6 Volt battery there for my 1937 Buick Century quite a bit cheaper than all of the other sources. A lot of places now have to special order 6 Volt batteries. Tractor Supply has them on the shelf. It seems a lot of old agricultural equipment that uses 6 Volt batteries is still in everyday use. 1 Link to comment Share on other sites More sharing options...
Spinneyhill Posted July 31, 2017 Share Posted July 31, 2017 If it were me, I would measure the space available, look up the "group" it belongs to (you probably already have that if the battery is a good fit in the box) and go for the one with the largest Cold Cranking Amps and largest reserve capacity. Then I would use the telephone to find a good price. Link to comment Share on other sites More sharing options...
buick special Posted July 31, 2017 Author Share Posted July 31, 2017 Hi Guys Thank you for the replies , at least I know now I can get a battery for it , I think the group is 3eh Link to comment Share on other sites More sharing options...
BuickBob49 Posted July 31, 2017 Share Posted July 31, 2017 The OEM battery for your car was probably a group 2E. They are still available. However, a group 3EH is a better battery--many more cranking amps and a much lower price. It is marginally larger than the 2E, but still fits the trays and hold down hardware on my 39 and 49 Buicks. Make sure that you have good cables. Link to comment Share on other sites More sharing options...
Marty Roth Posted July 31, 2017 Share Posted July 31, 2017 As Matt and others have suggested, the 3EH is your best bet, and Tractor supply is likely your best price - and likely to be fresh - but to be safe, check the date Code, and if not really fresh, have them order a fresh one for you . Another option I sometimes use, is to order a 6-Volt Optima from Amazon.com ($134.13 & FREE Shipping) they are fresh and affordable, and on some of our cars I even strap a pair of Optima batteries in Parallel, keeping at 6-Volt , but with 2000 cranking Volts https://www.amazon.com/Optima-Batteries-8010-044-Starting-Battery/dp/B00099HVN6/ref=sr_1_1?ie=UTF8&qid=1501544863&sr=8-1&keywords=6+volt+optima+battery Link to comment Share on other sites More sharing options...
buick special Posted August 1, 2017 Author Share Posted August 1, 2017 Thank you all for your help and suggestions , I saw a few of the 3EH batteries in the 80-90 price range but when you add shipping (sometimes $90 shipping ) price gets high hope to find one locally , a parts store says he has one but I want to make sure its a fresh one where is the date code and how can I tell if it is too old?

BuickBob49 Posted August 1, 2017 Share Posted August 1, 2017 I recall that my last ones were about $100 installed from the local Les Schwab tire store. They had a good local supplier of fresh batteries. In addition, each time it was nice to have someone else lift the old 50-pound battery up and over the fender and install the new one! Oh, my aching back! Link to comment Share on other sites More sharing options...

There will generally be a combination of letter/number for the month, and a number for the year, eg: 8-17 or H-17 might both indicate the 8th month of 2017. With some batteries, such as Interstate, there is also a stamped code somewhere on the battery, and if you phone their national toll-free phone number, they can give you the production date. Once while out of town, a distributor stamped a current date on a battery, but when I checked up, it turned out to have been manufactured some two and a half years earlier. The salesman said - "It is OK - you still have a year of warranty", but sitting on a shelf certainly would have reduced the remaining life expectancy. Buyer beware!

Podster Posted August 2, 2017 Share Posted August 2, 2017 I have two 40 buicks and they both have NAPA #7248 , 3EN, 875CCA, 1035CA@32F batteries that keep on going. They fit the tray and cover too! Link to comment Share on other sites More sharing options...
Dynaflash8 Posted August 3, 2017 Share Posted August 3, 2017 (edited) The original battery was a 2E and it is still available. However, I have found the 3EH commercial battery with 875 cranking amps is a little stronger. It is about the same size, but a little bigger. The battery cover will fit it with only slightly different and more effort. I just got one last week from O'Rielly's for $114 plus tax. AutoZone was $140-something plus tax. Tore my old hands up getting the old one out and the new one in and I have a factory battery strap with a handle. Two of them in fact. Now that is rare. I find all of the 6volt long skinny batteries I've had in recent years last about three years. A recent CarQuest battery didn't last a full year. Long ago I had an Excide that lasted 8 years. Golf carts use the 2E and tractors use both 2E and 3EH, so they can be ordered. They might be on the shelf in some farming areas. Batteries Plus didn't know what I was talking about and then when they found it in the book wanted a week for delivery. The heater hoses really got in the way, and I don't remember the batteries being so heavy. Maybe the 2E isn't as heavy.....Wow, at 79 I had to get my wife to help me pull it over the side panel on the '39 Buick.

WendyDee Posted August 4, 2017 Share Posted August 4, 2017 (edited) Here's an OPTIMA option, as I hate lugging around that big old battery. A friend of mine has installed one in his 52 and seems very pleased. They do also seem to offer this in the yelow top as well. https://www.optimabatteries.com/en-us/redtop-starting-battery/6v Edited August 4, 2017 by WendyDee (see edit history) Link to comment Share on other sites More sharing options...
