4 of 5 Great versatile charger September 5, 2020
Reviewer: BJSmith from MariAcopa, AZ United States  
I was excited to get this charger and try it out on some of my batteries that I had been having trouble charging with some of my other older chargers that seemed to be giving me unwarranted errors.  I had some older Powerex batteries that I used another brand charger and kept getting errors messages but as soon as I put them on UMS4 they went thru the testing and started charging without problem  The UMS4 did say that the batteries were in poor condition but it still charged them all and now I know not to expect much more life out of them.  The reason I didn’t give 5 stars is because some of my Ultrafire Lithium 14500 batteries need to be raised up in the battery slots to make good connection to the metal posts for charging but once I figured that out all was good and they proceeded to charge.
