I ordered one from Manafont

I ordered one from Manafont two days ago (edit: ordered Saturday, dispatched Monday).

European customers: MF advised that to get it with the EU plug you order the US SKU# and ask for the EU version during checkout.

From another site (?) I got the specs that state three current levels, depending on battery voltage (900, 700 and 500/550mA). Seems a clever solution for charge time and saturation.

I have no 26xxx batteries. I ordered this charger because some of my protected 18650s have a hard time to fit into the WF-139.

TR--5 is 1.5A, this one is 2

TR-005 is 1.5A, this one is 2 rails at 1A each. I am also thinking of getting this one, I don't mind the slower charge time, and anyway slower charging is healthier, not?

Not necessarily. Some of the seasoned members here with batteries/electronics have expressed there's sort of a sweet spot for charging. Too much or even too little can be unhealthy for the battery. Personally, I just try to get what's popular because I'm not ready to stress out about the health of my batteries. I've got my own health to worry about Tongue Out

According to what I've read,

According to what I've read, moderate current charging isn't actually that much slower.

Higher current (within the allowed range, up to 0.7C) during the first stage does bring up 4.2V sooner, but gives rise to a longer saturation phase (constant 4.2V until current drops to the 50mA termination level) for full capacity charge.

Although the above makes sense to me, I'm still just a messenger, so please refrain... Wink

Charging batteries at faster

Charging batteries at faster rates is healthier for your patience, it's way more important than couple extra months to lifetime of a $5 battery.

I wonder if TR-005 does the same… is this stepped charging better that constant current?

My take on this is that

My take on this is that charging a well-discharged battery with a higher current for a limited initial time only, will somewhat shorten the time to reach 4.2V, without the negative counter-effect of the longer saturation time that would arise if the entire first phase (up to 4.2V) were done with high current.

Quoting the full specs:

- voltage under 3.4V, current 850-900mA
- voltage to 3.5-3.6V, current 650-700mA
- voltage to 3.9-4.1V, current 500-550mA

Wut? Since when higher CC current slows down CV current drop-down? Theoretically higher CC current should make CV phase FASTER, as it heats up the cell resulting in lower internal resistance.

Quote:

Increasing the charge current does not hasten the full-charge state by much. Although the battery reaches the voltage peak quicker with a fast charge, the saturation charge will take longer accordingly. The amount of charge current applied simply alters the time required for each stage; Stage 1 will be shorter but the saturation Stage 2 will take longer. A high current charge will, however, quickly fill the battery to about 70 percent.

The “TR-005” charges up to 1.5 amps approx then ramps down as the voltage gets close to 4 volt and will keep ramping down till 4.2v with a very very slight charge once the light is green like most cheap chargers. In my very basic quick Review: Trustfire TR-005 26650 Charger from Manafont I called it a 26650 charger as a starting current of 1.5 amps in my opinion is to high for smaller cells and in my opening post i suggest only charging high end 18650,s nothing smaller.

Your not going to run into the problems mentioned on this thread when charging 26650,s with the TR-005 as 1.5 amps is about 0.3C charge rate (for king Kong’s and protected trustfire 26650’s), where on smaller cells like 16340’s its 1.8C witch is way to high, NCR18650A’s it is 0.50C.

When charging 26650 4000 + mAh cells there is a big difference in time of charging between 0.5 and 1.5 amps. I normally balance charge 3 × 26650 at once at 1.5 amps (0.3C) with my hobby charger and 2 to 6 18650’s at once 0.5 amps (0.2C) and it does not matter if they are sayno’s, panisonic’s or cheapies.

The hobby charger i uses the correct charging method CC/CV. And 0.3C charge rate or under is fine and safe for long life and keeping the internal Resistance low in the cells, it is a slow charger still but thats why i charge minimum of 2 cells to a maxim of 6 cells at once to save time and recomended the TR-005 for 26650 batteries.

Even the Trustfire TR-006 charger will charge a 26650 4000 + mAh at around 0.25C not a problem and a average 18650 2400 mAh at 0.4C but a 16340’s its 1.2C witch is still way to high to me, so i would only use it for good 18650’s and 26650 batteries.

To work out 1C = 1 x the capacity (mAh) % 1000

1 amp maxim IMO for an 18650 and i personally use 0.5 amp and a maxim of 1.5 amp for 26650’s and i personally use 1.5 amp for my 26650,s any thing under 1 amp for 26650,s is no good and will just take way to long to charge imo.

All figures and numbers are approx and is what Ive found works for me over the the years with just about all battery types and i could not recommend either charger for charging any battery smaller then 18650’s

Thanks for the info benckie.

Thanks for the info benckie. What is a charge rate, for example 0.3C as an example? So would I be right to say that if you have many different size batteries, the best thing is to have a hobby charger instead of multiple different chargers?

Mine came in from MF today.

Mine came in from MF today. My first impression is that TF brought the quality up a notch on this one. It came packed in retail clamshell packaging and included a product detail card with specs and instructions written in better English than I’m used to seeing from TF. The charger housing is kind of a rubberized plastic with the multicolored TF logo printed right on it. Overall, the look and feel is of higher quality than the UltraFire WF188, which I think is its closest competition. This one boasts a faster charge rate, but the UF-WF188 can accommodate 32mm wide cells (D-sized), so each has its advantage.

I dropped in a pair of LiMn 26650 cells that had open voltage of 4.09V and the lights went from red to green in just a few minutes. At first sign of green, the battery open voltage tested at 4.14V and 4.15V. Next test is on a pair of A123 18650 LiFePO4 cells. I notice that this charger shares the same complication as the TR005, which is that the negative contact protrusion is well placed for 26mm diameter cells, but for 18650 with narrow shrink wrap windows, the contact lands on the shrink wrap edge when the cell is laid flat. You must prop up the neg. end of the cell somewhat for it to make contact.

I am also observing that during charging of the A123 cells with the charger switch set to 3.0V, the red charge indicator lights are pulsing rapidly. I assume this is normal operation. Note that there was no pulsing observed when charging the IMR cells in 4.2V mode.

26650 and 18650 are merely cell dimensions. The 4.2/3.0V switch allows you to specify what chemistry of cell you are charging. Use the 4.2V setting for conventional LiCo chemistry and IMR chem cells, and use the 3.0V setting for LiFePO4 chem cells, sometimes called “nano phosphate” cells. Both chemistries are available in both sizes.

I just received four of these

I just received four of these chargers, and three of them were bad right out of the box! I e-mailed the seller on ebay and they said:

“hi,friend,
please don’t worry,we will do our best to help you.

we do check to it before sending out.
they are all on.
whether the line can not connect the power well?
please check it.

there were some chargers returned before,and we checked them again,it is ok.
if not work well,would you mind returning them back to us.
we will check and replace them to you,OK?

regards,

- rabbitword88”

I’ve tested everything. The one good charger, I unplug the cord from the back of it, try it in the other three, no juice. When I take any of the other three cords and plug them into the working charger, boom, lights right up!

I may just open them up and see WTF is going on. The cost to ship three of them back to china is $44USD Sad

Dead

>>>>>>>I just received four of these chargers, and three of them were bad right out of the box!

I just got one a couple weeks ago and it’s deader than a door nail. No lights. Nothing. Looks like this charger is an avoid.

I popped the covers and looked inside yesterday to see if it was something simple, an unsoldered connection or something. No such luck. Nothing obviously bad inside. In fact, I was quite surpised that there were so many components inside. Soldering was neat and well-done. Must be a bad component or two.

Pix of the innards

Here’re the innards of my DOA TR-006. Maybe someone will say: “See that cap numbered 897? A coat of nail polish will fix it.”

Red wires go to the charging rails. Nothing amiss that I can see, although the only thing that I could ID would be a disconnected wire or something equally obvious.

I’ve seen some REALLY sloppy and cheap Chinese PCBs, but this looks pretty neat and well done, although not well done enough to make the thing work. Wink

Because of your nice work so

Because of your nice work so far, I will disassemble my working AND non-working TR-006 and use my multimeter to determine where the two units start to differ Smile

Pics and info shortly.

I appear to be missing the “LED Holder” that’s in your pic:

And I’m pretty sure those aren’t supposed to be touching, and it looks a little different than your pic (the black thing with the copper wound wire).

Gonna rip apart the non-working one and take a look see Smile

Ok, so the first place where I can find any problems starting from the 120ac input is at C10 to the bottom of C19. The good one is 2.5v DC and the bad one is 0.5v DC Sad

I’m checking to see of anything “important” got installed upside down with the rest of the upside down resistors, lol.

Well, the one not working is

Well, the one not working is now totally fried. I was testing voltages around R3/R6 and the probe must have touched something it shouldn’t, sparks, smoke, doesn’t smell good. Now I don’t have power where I used to have power Sad

I filed a paypal dispute and like 20 mins later the seller agreed to ship me two new chargers free of charge (pre-tested ones, lol).

So I’ll only be short one charger, I guess that’s OK Sad

Good luck on your repair.

Thanks

Thanks for trying to help! That was above and beyond the call. I got my money back no problem on the broken one. I always go with ebay sellers with ultra-high feedback, even if their products are a little more money. I told him the charger was DOA and he refunded my money in the next e-mail. Never asked me to send it back.

Thanks again. Sorry your charger burned up. That’s awful. That was the good one right? That’s why I don’t poke around with a DMM. I would have fried something in the first seconds. Thanks for trying.

bad one also
I have one of these chargers also. Mine was from Manafont.The ac to dc power supply is dead.The charger does work fine with a direct dc input.I have checked all the solder joints and tryed tracing the a/c side but just got a headache.I could return it the MF but probably won’t bother…I’ll just use it w/5 amp 12v supply I already have.Supprised to see there have been others with the same problems with this charger…probably best to avoid it!-Rick

>>>>>probably best to avoid it!-Rick .

Now that you too have a broken one, I’d say it’s a definite avoid. Too bad. Was a nice-looking charger with okay specs, but after all this bad press, I won’t get within 10 feet of another one.

The seller agreed to send me two more chargers for free, to replace the three bad ones I got, so I’d be only short one charger.

Guess what, the two chargers they sent me are totally dead as well.

What the heck is going on? I specifically asked them to test the chargers before they sent them to me Sad

Uggggh

>>>>>> I specifically asked them to test the chargers before they sent them to me

Well, I suppose they could have tested them and they could work on 240/220 and not 120? But that seems unlikely.

Man, you’d think after getting burned once, they’d check the chargers before shipping.

Wow, good timing! I just heard from two friends the exact same thing! They shipped them back to china, tested on 240v, BOOM! Work perfect!!!

Looks like there could be a defect in the 110/220 voltage setup in the charger Sad
