Say hello to Andy - he's been absent from this site for awhile.
The batteries you considered are all the same type battery and all the same weight (~10#) and size, as supported by the common 'root part number' as follows: ?T14B-4are all 135CCA battries.?T14B-BS are nearly all 135CCA but there is a 200CCA in the mix (it weighs~15# is the only way to tell the difference). Those starting with "Y" are made in a Yuasa factory someplace. Those starting with other letters are made in some other battery factory (that is most oftenowned by Yuasa or GS Yuasa or under contract to them to build their batteries). These batteries are allmanufactured to the same Japanese 'international battery' specification.
They should all fit the oem battery box.
You got a good price, plus you get a ride out of the deal. Very nice!
