Nelson Posted January 2 Report Share Posted January 2 I forget the number for the original batteries but remember they where used in fork lifts. However, I’ve noticed some smaller more conventional batteries being used. I think they were used in a Honda but not for certain. Anyone know which small one I’m considering might be? Also, any information on availability of the original style. This car isn’t a show car so paying a premium to get the long original battery isn’t in the cards.

Dwight FitzSimons Posted January 2 Report Share Posted January 2 I believe the Honda battery number is 51. The dimensions should be available online. --Dwight Link to comment Share on other sites More sharing options...
psdenno Posted January 2 Report Share Posted January 2 If you have an O'Reilly Auto Parts store nearby, they have the correct 3EE battery for about the same price as a size 51.

Dwight FitzSimons Posted January 2 Report Share Posted January 2 (edited) Group 51 battery dimensions (LWH): 9.375 x 5.06 x 8.75" (weight: 28 lbs) Group 3EE battery dimensions: 19.25 x 4.25 x 9" (weight: 42 lbs) I suspect that a modern group 51 battery would be a better choice than a 3EE considering all factors. I will soon be doing the same battery swap on a '63 Avanti. --Dwight Edited January 2 by Dwight FitzSimons Link to comment Share on other sites More sharing options...
Nelson Posted January 3 Author Report Share Posted January 3 Thanks. The type 51 takes 14 pounds off the crack prone battery box. That is a big plus. I will look into both. Another plus for me with the 51 is it will fit into a Lark or Hawk I would think. I bought a 63 Avanti in Phoenix area. I’m headed out there late next week and would like to get the car running and driving. I’ll check the 3ee also. Maybe I can buy one dry and leave it on the shelf for a later restored car. I know you can buy a type 24 for a Lark at Wallmart for about $60. I wonder if they sell the type 51 or even the 3ee? Link to comment Share on other sites More sharing options...
EnduroDriver Posted January 3 Report Share Posted January 3 I think the big advantage of the group 51 battery is you now have access to superior battery technologies like AGM or Lithium. I was always puzzled by why the 3EE battery has such mediocre performance numbers for its size. Link to comment Share on other sites More sharing options...
Nelson Posted January 3 Author Report Share Posted January 3 It appears you could fit two type 51 batteries in the space allotted for the 3EE and put them in parallel. Of course you would gain a few pounds over the 3EE. Link to comment Share on other sites More sharing options...
tanda62 Posted January 4 Report Share Posted January 4 Here is an option I am considering: https://shopbraille.com/products/braille-g30-greenlite-lithium-battery At 6.4 pounds this really takes the stress off the fiberglass. Link to comment Share on other sites More sharing options...

That's a great price (Walmart) The group 24 I purchased at Auto Zone a few months ago was more like $150, and it wasn't even 'top of the line'!

mfg Posted January 4 Report Share Posted January 4 New manufacture 3EE batteries remind me of new manufacture 6V batteries, even with care they simply don't seem to last very long. Link to comment Share on other sites More sharing options...
