cub battery

Postby thiggy » Thu Aug 06, 2015 4:46 pm

My NAPA battery that I bought a few years ago when I refurbished the Cub has bit the dust and I will be replacing it. However, I was never pleased with the size and was unable to use the battery cover with my old battery (original battery box and lid). The NAPA # was 7217L. Is there another battery which might be a more precise fit? Oh, '49 6 volt Cub. Thanks, Folks.

Here is what you need to know about battery sizes, both 6 and 12V. I copied this and pasted it in a word file. I believe the author is "bob in CT," however I'm not sure since I did not have the good sense to save the author also.

Cub batteries

There have been many questions about buying a 6v battery.

Batteries are identified by "Group Number" in the battery industry. Group number identifies the size of the battery and the location of the terminals. The 6 volt battery used in the Cub is the same as the old VW Bug 6 volt battery and they are still available as they are used in golf carts, floor machines, signs and many commercial applications. Ask for Group 19L or Group 1 and you will get a 6 volt battery that fits. You may then get choices on battery quality and the best measure of this is cold cranking amps or CCA. The higher the number the more plates in the battery and that means you have more "power" available especially in cold weather when battery capacity drops. You can buy batteries at Sears, NAPA, or any other battery retailer that will order a battery for you if they do not carry it on the shelf. Interstate Battery has them in their on-line catalog under vintage cars. Use VW as the lookup in their battery finder, but you need to look it up in the vintage car section to find it.

I have seen some 12 volt tractors with the wrong battery too. I think a lot of battery box covers and fronts are lost when the PO came home with a battery that was not the right size so the covers were set aside and eventually lost. The correct 12 volt battery is Group 26R.

The Group 1 batteries you can buy at most places are too tall for the Cub battery box. Tractor Supply is too tall. Advance Auto is too tall. AutoZone is too tall. Napa is too tall.

Apparently the "group" dimensions are just rough guidelines, not exact measurements.

My experience is that recently I bought a 6v battery from NAPA that was a good fit although I did have to take some rubber off the cover's hold downs.

19L is what I buy and they fit nicely in my battery boxes... Interstate usually has them in stock which I like as does Battery Direct. I won't buy NAPA batteries again .. don't last and don't fit ... :-(

6V is getting harder to find in any size. A down side of any in stock 6v battery is it could have been sitting on the shelf for a long time.

Best bet is Interstate. I have seen their truck at the local Cub Cadet dealer, so possibly you can get a local place to order one for you if there is not a store nearby??
