These batteries are the biggest headache. Yes, they have longer battery life and vape better but they also have the following problems:
- Cleaning is more difficult. The small groove around the centre post fills up with black gunk and only the slightest amount seems to prevent contact.
- It is not compatible with older KR808 chargers/PCCs or adaptors with KR808 threading. Screwing these in too tight can damage the centre post and lose contact. This is because the centre pin on chargers/PCC's dents or moves the centre post.
- On the subject of the centre post, it moves very easily and needs nudging about to re-establish contact. This often happens after attempts to clean out the gunk mentioned above.
- A clearomizer will run off a KR808 version 1 battery fitted with an adaptor but not off the version 2's.
- Most KR808 adaptors on the market also have the centre pin which damages KR808 type 2 batteries.
I'm sick of the frustration caused by these batteries and am seeking a reliable source of KR808 version 1's. They are sold out everywhere I've looked so far and those that have them do not ship 'Down Under'.
Otherwise, it's 510 batteries for me. The above issues are sufficient to make me switch. So much for lightweight portability and elegance.
Has anyone else noticed these issues? Does anyone know of a KR808 Version 1 source with USPS First Class International shipping?
