Insten 2X LI-50B Battery+Charger Compatible with Olympus Stylus Tough 8010

i was having an issue where this olympus tough tg4 camera won't charge um it has a battery in it i have two batteries so i put both batteries in neither of them power up okay if i have it plugged in it powers up but as soon as i unplug it the power goes out so um you know i leave it plugged in overnight and it won't charge in there we go so um i was trying to figure out what's going on i could not figure it out and it also wasn't showing the battery light at the bottom here now what i figured out which was seems really ridiculous now that i figured it out is the battery so i was putting the battery in like this the battery look at the bottom has this little tabs can go in backwards so if i put the battery in the correct way there we go now it'll actually start charging so if you have one of these cameras and you're like it's not charging it won't power up blah blah it seems really ridic
