e-cigars, rn4062 and dse701 battery question

[serrada36]

Hi,

Just picked up one of each a rn4062 and dse701 . I origanaly thought they used the same batteries and both manuals say they use 3.6v. The 4062 was shipped with and uses a 3.6v and the 701 I got was shipped with 3.7v's.

Is there any harm in using the 3.7v's in either cigar or chargers?

Thanks in advance!
