Will my charger work?

Hello fellow vapors,

Quick question, will my Trustfire TR-001 Charger charge my Aw 3.7v icr 123 750mah batteries.

Thanks

Yes, it will. Well, I mean if it is in working order. It is compatible with those batteries.

Hopefully you have a DMM to check the voltage when they come off the charger. My TR-003 always over-charged my batteries a bit. They should end up at 4.20 volts or a little less.

Mine were coming off the charger at 4.23 volts.

Yes. Just check your batteries before going on the charger and then coming off. Once off the charger, let them rest for an hour before using.

TR-001 is made by Trustfire, not Ultrafire.

Dedicated 16340 (RCR123) charger is always much better choice (Full size 18650 charger usually provide much more current for ICR 123 ), but if you do not have anything else for your ICR batteries... it is probably OK . As previous poster said- it is important to find out what is open circuit voltage reading from freshly charged bateries - anything below 4.21V is OK (measured after charging is completed). After "resting" 30min. they should be btwn 4.14V-4.19V.

Thanks for the replys. I think this is a good excuse as any to run out and get a multimeter.

Don't forget li-ion charging (overcharging rule) If freshly charged li-ion batt. gives you reading of more than 4.22V do not use that charger.

Your charger is probably fine, and I am saying this because xxxfire chargers used to be known for overcharging li-ion batteries which is big no no.
