Review on Keenstone Universal 18650 Battery Charger - Recharge Li-ion, LiFePO4, IMR, Ni-MH, Ni-Cd, AA, AAA Batteries (NO Charger) by Steven Ripley

I have only used the charger twice and I really liked that it tells you when each one Battery is charged. I love the design and the ease of use. Batteries take a while to charge and seem to be losing some charge after being left in a drawer for weeks. To be honest I've read that rechargeable batteries need to be charged from time to time and they actually lasted about 4 weeks from my first charge. I would definitely buy this product again as it works well and is nicely compact. Five stars for the charger, four stars for the batteries.
