Hi, I received my Torpedo PV the other day and so far am pleased with its performance. It's the battery charging that is making me a bit anxious. I have been reading about lithium ion batteries and have come accross some horror stories about them catching fire or exploding. I have heard mention of 'protected' and 'unprotected' batteries, I assume the supplied batteries are protected, right? The instructions provided state that the charger should not be left unattended so there must be some risk. Anyway, I first attempted to charge the two (depleted) batteries at the same time, which went on for 8 hours before I unplugged the charger before going to sleep. I put it back on in the morning (Is it wise to stop and then resume charging?) for a further 4 hours before giving up. Both batt's gave a reading of 4.1 V. There is some info on lithium battery charging here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries. Looking at this it seems as though I stopped charging during the 2nd (Saturation?) phase. It also says that not charging to capacity can be good for the batt's life expectancy but TW say to ensure that the batt' is fully charged. I performed another charge of a single battery today and gave up after 7.5 hours. Should it really be taking this long? Again, it came out at 4.1 V. It is obviously impractical to babysit a charging battery for over 7 hours so is it ok to take them off early? or can anyone recommend a faster (and safe) charger? Not to imply that the supplied charger isn't safe. Any help that anyone can provide for these issues will be greatly appreciated. Even if it is just to tell me I'm being paranoid. Cheers, Peter |

Hi Peter
All I can say here is that I leave my batteries charging unattended and they have been asolutely fine. Sometimes it seems manufactureres give these warnings to cover there own ass. My batteries take 3 hours to charge when depleted.

When you put your batteries on charge do you put the batteries in the charger then plug it in? If so then that could be the reason for the long charge time/indicator not switching. You should plug the charger in first then put the batteries in the charger. If you're doing it the 'right' way round then I would contact TW as it may well be a fault with the charger. As far as partial charge cycles goes, they will have no adverse effect on the batteries, Lithium batteries don't have any 'memory' issues.

I didn’t time the charge on my batteries but it was nothing like the times you state Blackacid
I estimate 3 – 4 hrs.

With regards to StevieD's post, it turns out I was doing it the 'wrong' way round! I'll try doing it properly tomorrow.
But what about about the risk of explosion if left unattended?

The risk, while present, is minimal....What I do is check the batteries I've put on charge after about fifteen minutes and again after about thirty minutes, just feel the batteries in the charger and as long as they're not getting hot should be no problems. I do this with all my rechargeable batteries and in over two years of vaping have only had one battery start to heat up, I pulled it out and binned it straight away. |

Probably the same risk as with your phone, no one ever bothers if the phone is going to explode.  |

I have the same charger and different vendor 18650 batteries for a dif mod. Had it about 8 month's or so and never had any problem's
Trustfire batteries are some of the best out there atm so i doubt there charger is gonna be junk.
What company TW get's there 18650 batt's from i dunno as there TW labled, but there protected so I don't see there being a problem.

some lion and lipo batts would catch fire in rare cases, generally overcharged unprotected batts using shitty charges and being overdrained by @#$% equipment. the techs safe but many horror stories from crap kit. just my exp from working with airsoft guns using lithium batteries.

Just tried to charge my batteries today for the second time and the charger made a high pitched noise and started smelling. Sent email to TW, I think the charger is toasted. I am assuming the red end of the battery is the + end correct?

Yeah the red end is definitely the positive (+) end of the battery.

All four of the TW batteries I have take about six hours to charge in the supplied charger. They show 4.1 V when fully charged and I put them on to charge when they've dropped to 3.5 V as the performance is dropping off by the time they get down to that level. I do leave them unattended when charging but also check whether they feel warm on occasion if I'm around. So far all seems fine.
