I had clean all the connector as advised and also took out the grounding cable and brush it before reinstall it. Test all connector with ohm meter and all seems low resistance. Then i took her out for a ride till hot and swap the battery from my friends bike and it crank easily. Only the original battery seems weak when hot. And Max is right, I had only change the battery less than a year, but already pass the 6 months warranty. Its a Bikemaster brand AGM. Guess its time for another battery again. The heat here can range from 27C (80F) on cool day to 40C (104F) on a hot day, and my car thermometer sometimes show 42C (107F) park under the hot sun during noon... Maybe its the heat that shorten the battery life or due to the lack of riding recently due to pandemic...
Yeah, beware: Not all AGM battery quality are created equal.
