I have diamond and stealth batts in manuel and auto and I have been charging them on v4l standard usb charger for some time and thought nothing of it. But now Im wondering, can someone tell me if I am supposed to charging either or both of these types of batteries on a slim line charger instead? Is using a usb harmful to these batteries?
Thanks.
