Changing the Battery on the Dermlite DL3N (and DL3)
Replacing the battery on the Dermlite DL3 is easy and only takes a few minutes! So if you notice your dermatoscope isn't holding a charge quite as well as it used to - and especially if it's more than a few years old - you may want to order a new one!

NOTE: The Dermlite DL3 and DL3N use the same battery. The two dermatoscopes are nearly identical, except that the DL3N provides "PigmentBoost" lighting, whereas the original Dermlite DL3 does not. Other than that, they're identical.
