Are all 8D batteries standard size?

I am back in the states and my boat is on the other side of the globe. I lost my notes with my battery dimensions that I need to replace. I don't have any experience with these batteries because this is my first time to replace them.

I know I have 8D batteries. Are they all the same dimensions? Regardless of Ah capacity?

Thanks

They're supposed to be. 8D's do vary considerably by weight, depending on construction details, but they should be pretty close to a standard size.

Isn't there anyone you could trust to measure the ones you have?

Another option might be to use other battery sizes while you're at it, like 6V golf-cart batteries. With a little ingenuity, it's sometimes possible to squeeze in more amp-hours in just about the same space, and to do it using batteries which won't break your back like 8Ds will (e.g., 70lbs each instead of 150lbs each :-)

No, they are close to the same size, but not quite. If you have a critical dimension, like height, its better to measure beforehand than take out the chisel or grinder (like I had to).

I agree. I had a space that was X by Y and the batt was X by Y but it had 2 little tabs on the base that stuck out further. I had to file them off with a wood rasp. I'm sure I voided my warantee.
