Roy 0 Posted March 3, 2007 Before I start measuring and doing a site search does anyone know off the top of their head if a group 51 battery will fit in a B-1, 700, or 725?? Thanks, Share this post Link to post Share on other sites
MDB 134 Posted March 3, 2007 Roy, I do not think that there is enough room between the dash and the fuel tank. Share this post Link to post Share on other sites
LPH-5 0 Posted March 3, 2007 I have a B-110 & the last battery i put in it that fit like factory was one that fit in a HONDA S2000 (little sports car) just got it off the shelf at store. Will try to look later..(oops its a group 51 so guess it won't work) Share this post Link to post Share on other sites
Roy 0 Posted March 3, 2007 OK, I did the research. Results as follows: Group 51 battery: L = 9 3/8, W = 5 1/16, H = 8 13/16 Group U1 battery: L = 7 3/4, W = 5 1/16 to 5 3/16, H = 7 5/16. Group U1 width varies slightly depending upon the manufacturer. A Group 51 is too long for a B-1, 700, or 725. May also be too tall. The hoods are a close fit over the top of a Group U1. Now I know.

Roy 0 Posted March 3, 2007 Paul, Your picture raises an interesting question. Are the battery terminals supposed to face the front or rear of the tractor? All mine face the front. Also, I highly recommend some sort of non conductive shield/gasket between the gas tank and the battery. Vibration and battery acid tend to wear and corrode the tank in the long term. P.S. My B-1 Parts Catalog shows an insulator and tank gasket between the battery and gas tank but I have never seen these OEM pieces on a tractor. It also shows the battery terminals facing the engine.

MikeES 453 Posted March 4, 2007 To help prevent corrosion to metal parts I use pieces of vinyl flooring. I put piece under the battery and on the FDT tractors, a piece between the battery and the gas tank, and a piece between the battery and the outside shield/cover. I works great! On the RBT tractors only a piece under the battery is needed when using a 22NF battery (plenty of clearance all around). Share this post Link to post Share on other sites
