18650 is a size declaration. HOWEVER, Not all 18650s are 650mm x 18mm. some may be 17600 or even 19700. Make sure the SPECIFICATIONS of the batteries you choose match what the DT battery clip says it can fit.
Unprotected cells may fit better but you MUST BE CAREFUL when putting them in as polarity is EXTREMLY IMPORTANT and reversing this may cause detriment to the battery, the device or both.
