I shouldn't be too frustrated since my battery has lasted 11 years without any maintenance at all, but it is starting to get a little weak so I purchased a new battery after doing some research. I chose to go with a Moto Batt battery which has pretty good reviews. The only negative that I seen was that it is yellow in color. So I went to do the install this evening. Pulled old battery out went to put new battery in and NO GOOD! It will not fit. The battery has the same measurements as the original but there is a cut out or an indentation on the top of the original battery that slides under the hold down bracket and the Moto Batt does not have this cutout. I think I am screwed. I sent them an email but after looking at return policy it says that return battery shipments are not authorized because they are hazardous. I got the D@mned thing shipped to me without any issues. What the #&*! ? This is the battery that their site calls for but it definitely does not fit. So take note do not purchase this battery even though they say it will fit! The battery # is MBTX12U
