Time will tell if I made a worthwhile investment with these instead of Al AAA batteries. How many charging cycles they will hold up to will make that determination. The batteries with a 4 in 1 USB charging cable makes a nice kit. Took about an hour to charge batteries & measured a solid 1.5vdc. They will see lots of use in several applications & if they give equal performance to Al batteries I will be purchasing more. Richard

I was sceptical of how accurate the rating of the cells on these AAA batteries was going to be but since buying my first set of 2 I've not been disappointed they are really well made the micro usb port is very sturdy and battery than some of my smartphone ports it has a red LED that is a ring at the positive end which turns green once fully charged so you'll know if it's charging or not they aren't too heavy and they are the same size as Standard AAA by 0.01mm accuracy Great Product!
