[QUOTE="M3talmiliti4, post: 242369, member: 6438"] I also considered one of these batteries for my 4500 but because the original battery is buggered i have opted to go with the genuine minelab battery as it will be the main battery not the spare. Considering there are no (extra) electronics within the battery, pretty sure they are, as you said, camcorder lithium ion battery cells. According to the 4500 manual a minelab gpx battery fully charged is 8.2v - 8.4v and the electronics in the minelab battery shut it down at 7.1v, so i spose as long as the fully charged voltage doesn't exceed the 8.4v stated in the manual then they should be fine. Sorry i can only give technical advice not practical experience with these batteries. On a side note i would be looking at the amp hours of the battery so you know roughly how long they will last between charges. Hopes this helps mate. :) [/QUOTE]
