    Great charger. Might confuse those who are very technologically challenged, but for anyone who understands anything about batteries, it's awesome. I have a lot of random NiMH batteries and I used to to determine the condition of each.

    Great Li-ion charger. Got my Milwaukee M18 XC 8A battery pack back to normal (in sync). Great for charging 18650 cells.

    A high-quality battery charger. Very useful for folks like me who have 18650 powered devices (or any battery size for that matter that the charger supports) and want to charge them using a battery charger that actively maintains the health of the batteries.
