[QUOTE="WayneF, post: 355908, member: 12496"] I think some of those are lithium ion now... Overcharge is sort of serious, so lithium ion (camera, smart phone, laptops) have semiconductor chips in the battery pack, called coulomb counters ( [URL="http://www.google.com/search?q=coulomb+counter"]coulomb counter - Google Search[/URL] sometimes called gas gauges, not sure that name is a plus?) These chips monitor and counts the current flow in and out, and can report the charge status (that third pin on our camera batteries), and adds some of the expense of them. But the chip protects against overcharge, and disconnects them when charged (so you can leave them plugged in). I would qualify the need for a spare camera battery in one day. Video is something very different. :) [/QUOTE]
