M401, 402, and 403

[mrmack00]

I'm looking for replacement parts for my 401 some questions come to mind. can I use the same refillable cartridges and the same atomizers if I just bought a 402 and 403 battery? '

I ask because I saw this cool cigarette case looking thing that charges 402 and 403's but it's not listed for the 401.

I appreciate your help.

Yup, they're all interchangeable, the only difference is the length of the battery. I have the M402 charger case and it will charge the 401, but the lid won't close.
