Q: Why is the battery 3.7V and the charger outputs 4.2V?
A: The charger is limited at 4.2V, but does not go to 4.2V immediately when the battery is just plugged in. It first charges the battery at a constant current until the voltage reaches 4.2V. Then, it stays at 4.2V for a few minutes. Then it shuts off and the LED turns green. This is according to Li-Ion charging specifications (optimal voltage is 4.2V, nominal at 3.7V). It is different from Ni-MH or Ni-Cd battery charging. Read our Forum for battery charging tips.
Q: Why would the LED turn red and immediately turn green with my battery?
A: Your battery is "dead". It has lost over 90% of its capacity. This usually happens when you overdischarge the battery too much. Read out Forum for battery usabe tips. You need to get a new battery.
Q: The LED never turns red but my battery works. Is the charger bad?
A: There is a chance the battery terminals do not touch the charger contacts all the way or became dirty. Please, check that. If necessary clean the battery terminals or slightly bend the charger contacts to have a better connection. If this is not the case - then yes, the charger is bad. Generally, these chargers have a very low rate of returns. Less than one in 500.
