This would seem to be the new one , that fixes what was wrong with the previous one :thinking:..
Anyway , Open Circuit = 4.2volt Charging Volts 4.05 as near as I can tell .
2 channel charger .. Seems to charge at a constant rate that drops as the battery becomes loaded . [ Nice ]
Charge rate :
1. With a 18650 @ 3.69v C1 does o.55A C2 does o.5A
2. With a 18650 @ 4.13v both do o.12A
2.B 18650 @ 4.17v Charger is varying from o.o4A to o.o7A
2.C 18650 @ 4.2v Charger is still charging at o.o2 - o.o4A - No green light as yet [ Trustfire 2500mAh Unprotected ]
3. With a RCR123A @ 3.91v both do o.31A
4. With a RCR123A @ 4.07v both do o.15A
5. With a RCR123A @ 4.11v both do o.12A
6. With a RCR123A @ 4.17v both do o.o8A
Im currently charging a 18650 to see where it terminates .
Then I will do a RCR123A
Well , I must say im impressed with the TR-001 , its a very clean and un-cluttered looking charger , it also handles RCR123A to 18650 with no problems or spacers needed . The case seems to be very robust in construction , and the entire unit does not seem cheap at all , it in fact feels - looks - and handles like it should cost more .
Speaking of price , $8.81USD
Just waiting on those batteries to charge now .. Ok I used the left channel to charge a 18650 Trustfire 2500mAh Unprotected batt , when it hit 4.22 I pulled the batt out and tried the right hand channel and it would not go red , Im currently charging a CR123A in the right hand charging slot , but it looks like the left side may have a problem and overcharge . I will try the right side with a 18650 [ Same brand etc ] to see if it works ok ..
Currently charging a RCR123A in the right hand side ... Ok looks like about 4.22volt on the right hand slot for termination voltage , after resting the batt for 2 minutes , its reading 4.19v [ RCR123A ]
Conclusion
Ok bottom line , it overcharges and just does not look like it wants to shut of or go green at all , I just left the 18650 in there and it hit 4.23 no problems and looked like it just wanted to keep on going . If they could fix the overcharge problem , this would be a great charger , as it is , I can only recommend you dont put it on your shopping list .
For a while there it looked good , I liked the way it charged the batteries , dropping mA as it got closer to 4.2v , but there is the crux of the problem , it just does not look like it wants to stop charging .
Great product if your looking burn your house down .
