I only seem to get about two years with a standard 14L-A2 lead/acid.
I also have noted that my batteries can overcharge a tiny bit during the year and I have to put an ounce of water in occasionally.
It is new this March but I'm going to try taking the battery out and bring it in the house at the end of the riding season this year to see if it last any longer.
