Hi guys, I understand from some audio shops that upgrading to a bigger battery has a lot of benefits in terms of stability, especially when the sound system has been upgraded with more components. I have also been seeing a lot of Japanese owners change their batteries to this Panasonic 60B19L model. They have given it mostly good ratings too, though I can't pinpoint its exact benefits from their reviews. Has anyone tried upgrading to a bigger battery? Any views to share? cheers
