Charge time is a function of how many 18650's you are charging, and how 'discharged' your 18650's are. With 2 18650's in the independent slots, the charge current is 750 mA. So to fully charge a 3100mAh cell, about 4.5 hours, with 3400mAh Cells, closer to 5 hours. If you have all 4 slots in the charger in use, the charge current is effectively 375mA, so figure about 8 1/2 hours for 3100mAh cells, and about 9 1/2 hours for 3400mAh cells. However most people recharge before the cell is fully discharged, so your times will be somewhat shorter. YMMV. If you want faster charging times, you might look into an Xtar charger such as the SP2 (up to 2 amps), or VP1 (up to 1 amp). The main drawback of the I4 with 18650's is the long time it takes to fully charge large capacity 18650 cells.

Hi Matthew,

Thank you so much for your detailed reply. My first set of 4 - 18650's were going on 7 hours to charge. These are new to me and I was just a little concerned. I prefer trickle chargers anyway so as not to stress the batteries. I have no problem waiting. Thanks again!

Hey,

I was waiting for the Xtar XP4 to come out and it looks like it has. HKJ doesn't have a review on his site yet though, has anyone reviewed this? Searching looks like it might have problems with NiMH termination, though it may have been the person was charging at too low an amperage. I was hoping it would be a great multi-chemistry charger.

Now I'm just looking for a good Eneloop and 18650 charger, but I don't want to have to spend $100+ for an MH-C9000 and a VP1.

Looking for a 18650 but which one? I'd like panasonic Gonna order from fasttech I've heard some bigger mah may not fit. I'd like a protected battery. I'd also consider a protected Sanyo from the same source.

18650 Charger question.

What is the largest number slot charger for 18650 batteries? Do they make a charge that charges 8 or 12 batteries at one time? I have a TK75 with the two extensions and it holds 12 18650 batteries and would like to charge more than 2 at a time.

Thanks!!

XTAR WP6 II does six at a time.

You could get a hobby charger and probably do 8 or 10 but they don't have pre made cradles.
Or atleast I haven't found any with pre made 18650 holders.

Battery/charger help

Ok, it's been a long while since I've been around so please forgive me as I'm sure this has been asked a million times.

I have a SureFire 6P that has a single cell rechargeable battery (I forget brand/number), a WolfEyes 9DX (uses 3 - CR123's) and I'm thinking about getting a Fenix PD32G2. The charger I have is broken.

What's the best but not crazy expensive way to go rechargeable on everything and have one charger to charge them all? I started to look at the Fenix kit but I'm guessing I'm going to end up with two different sizes of batteries and the charger in the kit only does one size.

So, what batteries and charger (links please)?

Thanks in advance from this old noob. :candle:

Re: Battery/charger help

I just dropped in a Redilast ( http://edcplus.com/ ) 3 mode XM-L2 U2 in my 6P LED and bought two of their Sanyo celled 17670s and can't complain. For $70 shipped, I took a woefully anemic light that I got lucky and paid $35 for and turned it into something I'm not embarassed to carry.

As far as chargers go (and I have a PD32 XP-G R5,) I use an Xtar WP2 II charger for $20 shipped. You can look into their SP2, VP1 and WP2S chargers, which test out well and top out at $50.

I don't know what you'd do with the 3xCR123 light, but you can run the 18650s and 17670s in the other lights.

I removed a few 18650 batteries from old laptops , have put 2 pairs of batteries with solar panel and a 7805 regulated O/P from panel to a Li-ion charger. Seems to be working great. With one USB port in it I can now charge my phone and GPS while on a trek.
