Good solid 18650 battery charger
on July 19, 2013
For reasons that still mystify me I've begun acquiring devices that use the 3.7 volt 18650 rechargeable li-ion battery. Thus, this purchase.
Unlike many other battery charges you can buy for these batteries, this charger will charge _only_ the 18650 battery. It is capable of charging one battery at a time and also charging two batteries of different charge states at the same time.
Seems reasonably well-made and charges 18650 batteries from a state of about half-depleted to fully charged in an hour or so.
One quibble, the left charging station has a base spring that was installed slightly off centerline, so you have to fiddle with the battery you put in that station to get it into a position where it stays put. That's probably an issue of someone being sloppy during assembly.
Each charging station has an led light that indicates the state of the battery while charging. Red = charging, Amber = nearly charged, Green = finished charging.
If 18650 rechargeable batteries become part of your life, this is a good way to get two batteries and a dedicated charger.
