So my guess is that the battery is not the problem, right?
What is the "regular one" ? Make sure it is a good battery for your bike. It must be more than 200cca, should be AGM not liquid as it does not stand streight. You'd better have the original one which is the HD part OEM 65948-00A B or C. This battery is AKA the DEKA ETX14.
