986 AGM Replacement Battery Exact Fit

[Eric-986]

Check that the "outermost" position on the battery mount is threaded. My 987 has a hole for the H8, but it wasn't threaded and needed some work to make it usable (pain in the butt, worried me about scratching the paint, and ending up with rust eventually.......)

I have had some luck by charging them while also having a second (good) battery hooked up to boost the voltage.
