Review on Rechargeable AAA Lithium Batteries With Micro USB Charging Port - 1000 Cycle, 1.5V/400MAh - Pre-Charged, 4/Pack by Jasmine Williams

I bought these to use with my wireless mouse and presentation laser pointer with my notebook computer. As much as I was going through AAA batteries, I tried these as an alternative to possibly save money. Good choice! They might seem a little "steep" at first price-wise but over time they will more than make up in savings versus the cost of OTC AAA batteries. As for long lasting, these are great. I've charged them up and with nominal use (my experience) they last a good long time before I have to recharge them. The little 4/way USB charging cable that comes with them is both handy and convenient. What I really like is that there are orange/green indicator lights on the batteries that let you know when each of them is charged. No guessing! Highly recommend these!
