What does the display say when a process is finished?

Now I can answer it myself, it says “full”. Since I was doing the ‘refresh’ cycle, I wasn’t sure it was still operating, or had finished, but it does seem to have improved my old 2500, blue Trustfires.

The real bad one is still being refreshed and is at 4.16v, and up to 108f at it’s hottest spot, the one that was just old and tired, came off at 4.20 and 2016mAh.

Actually, it is still running on the worst 18650, and it is two days later, about 2.5 days after the first one finished the refresh cycle.

Should I be worrying?

As far as I know, only Nimh cells gain from “break-in or refresh” mode. Li-Ion do not, you only hasten its demise when doing so.

I thought that was the purpose of this charger, that it would refresh a Li-Ion battery like the c9000 does for Nimh.

The first one of the pair came off at 4.20v, but this second one reached 4.2v, and now is back at 4.13, 4.14, and 4.15, I’m wondering if it will get back to 4.2 and just say “full” at some point, or if it is frozen in some cycle?

It does get hot spots of up to 109f at times, in temperature.

you can not buy the charger at $39 and use your $2 coupon
look like the $2 coupon is for future use, and can not be combine with any other discount… sheesh :Sp

I will try to find that article concerning refreshing a Li-Ion cell being not beneficial. Anyway, doing a charge/discharge cycle on li-ion doesn’t do any good to them, it’s even harmful!. I have experimented this with my hobby charger. You just do more damage by decreasing its life-cycle. Remember, li-ions does not even like to be deep-cycled, not even fully-charged (which is ironical) nor deep discharged. Read battery university’s article on it.

If you don’t have a hobby charger, I believe one of the better features of this charger is its ability to discharge-capacity test a cell/s, thereby avoiding the ‘guesstimate’ of knowing the health of your Li-ions or any cell for that matter, aside from its other features. This way, you will know when to finally retire your beloved cell!

The Refresh Mode, on the other hand, is really beneficial to NiMh.

Hey Bro,
I will take it up with Dora tomorrow when office hour starts. Thanks

You should have low confidence in GB. It took them almost two weeks to get mine in the mail, and I chose express shipping. I ordered a TR-J20 from them on Wednesday (to spend the store credit that they gave me for express shipping last time). It was expensive enough that I got free express shipping, but once again, it looks like it’s going to be a long wait — it’s been two business days, and they haven’t shipped yet. (OTOH, mountain electronics, from whom I ordered the batteries, shipped immediately).

[jmpaul320]

i guess expedited shipping does not mean expedited processing lol

mines been sitting for 2 days … i should have just gone with the free shipping

I went with free shipping. Ordered on May 7th. The package just popped up having gone through Chicago customs and now at Chicago US post office. If things go as normal, I should have it in about two days.

Ordered on 05/01/2014
Finally got an update with great news!
2014-05-14 21:56, Processed Through Sort Facility, ISC NEW YORK NY (USPS)

There’s a good chance I’ll see it on Monday May 19!!! 3-5 days from NY to Marengo, IL

Finlay got my unit on 15th May free shipping. I received “has been shipped” status on 30th of April. I am currently charging KK 18650 cell in slot 1 at 2A. In slot 4 i put 18650 cell and set charging at 1A. In slot 3 a put another 18650 cell and also set charging at 1A. Soon after that, charging current in slot 1 went down to 1A. This charger has 4A charging current 1A for each slot and can also split 4A evenly into slot 1 and 4 right ? So while slot 1 uses 2A other two slots should have 1A each available, am i wrong ? Meanwhile slot 1 reduces charging current form 2A to 1A (at least so indicates LCD), so the charger operates at 3A max with three slots occupied. I also noticed that, when i set 2A at slot 1 or 4 and put second cell in slots 2 or 3 (2A in slot 1 and 1A or 2A in slot 4 works fine), the charging also reduces form 2A to 1A in slots 1 or 4. Is it normal behavior ? Am i missing something in spec ? It may happen you start charging one cell at 2A slot and you decide after 1h to charge second cell in slot 2 or 3 which results you got suddenly longer charging time in one of “2A slot” due reducing to 1A.

[dazed1]

Its 4A max, no matter how you mixed it. 4x1A 2x2A….the 4A is the max.

The charging current can be selected for 200mA, 300mA, 500mA, 700mA and 1000mA.
If only bay 1 and/or 4 are used to charging batteries, current 1500mA and 2000mA can be further selected.

Hello dazed1,

GearBest.com offers three types of shipping: flat rate shipping, standard shipping and expedited shipping. Just go to product page on GearBest.com, there is a detailed chart about each type of shipping time. GearBest.com offers FREE shipping, which is “Flat Rate Shipping” which usually takes from 10-25 business days, and buyers can choose to pay additional for Expedited Shipping, like DHL/FEDEX, which takes only 3-7 business days.

We also hope you can understand that shipping time is dependent on the respective courier.

It will be so kind of you if you can recommend other faster shipping ways, we will try our best to list them on our shipping partners.

Thanks!
