The Tenergy Lithium-Ion battery chargers you may have purchased from our recommended source, All-Battery.com, have a little quirk that is worth noting.
The LED indicator is quite simple; Red = charging, Green = Fully charged. However, if you connect the charger to the battery without turning on the power to the AC input, you will also get the green LED. The battery powers the LED when the power to the charger is off. This can trick you into thinking the battery is fully charged, when in fact it may not be.
Despite this little hitch, I love the simplicity and low cost of these chargers. I have been using them for quite a few years now with no problems.
