hi there,

I promissed a while back to do this post, and although I'm only here occasionally (mostly using a local dutch forum), a promiss is a promiss.

A while back (jan 5th) I came back to vaping.. having strayed from the right path for over a year..
So.. time to bring my eRoll out of it's long wintersleep and hang in on a power socket.

Allthough the led's came on, red, blue, green, all at moments it should.. the PCC (Portable Charging Case) was actually doing nothing else then throwing on the lights.. a full night's charge equalled about 10-20 puffs.. that's all she could still handle.

So.. googling around I found the ECF forum, and a post about a year old and this being a 752080 battery.
It didn't however show the results of replacing the battery, so I promissed to do so here.

Opened.. and the original is a 3.7v 1000mAh battery type 752080.

I used this link on to get a new replacement battery from China for $ 8,08

That link now however points to this one:

And it's probably a new link next week.. if you do a search on 752080 + battery you'll find it on Alie.

PLEASE NOTE!
The original battery is stuck to the PCC with a very sturdy tape!
It will require some force to remove the battery from the case, however do it patiently.. otherwise you'll wreck the case.

Strangely the new alie battery is labeled a 702080 and not a 752080.
I do not know what the difference is, but the size is identical, the power output too, and most important ; it works..
so i'm taking the difference for granted.

If you are wondering if you should/shouldn't do the replacement..
well, anyone who has had simple experience with a soldering iron can do it.
If you have never used a soldering iron.. get your hands on a 15w soldering iron/pen style.. nothing heavier.
Practiss a bit on attaching/detaching elsewhere.. it basicly is one of the most simple soldering tasks so even a novice could do this,
just make sure your iron comes from above on the board, and not too much sideways (or else you'll fry the chips or battery :p )

So basicly.. it's detach the red and black wire.. remove old battery, and connect the black and red wire of the new battery.. tadaa :)

NOTE!
Tape-off the red wire once it's detached from the board.
Even though that wire goes to your "dead" battery, you don't want it making a shortage just incase.

Closed up.. and a couple of hours charing later... Ah.. the lovely green light :)

It seems like my simple battery replacement solved the problem with this unit.

A new PCC costs 25 euro's in the Netherlands.
This battery replacement is less the 8 euro's.

If you have an eRoll that's been put aside for the same reason, you might find this post helpfull :)

This eRoll is going back to friends/family that are considdering vaping, but still have the need for something sig-a-like.

ps, sorry if this post is in the wrong place
