Best laptop battery tester? Opus?

Post by jimbo69ny » Feb 14 2018 10:25am

I searched but I didnt find an answer.

What tester/charger do you guys like? I have heard mixed reviews of the Opus. Also I have read that the Opus doesn't read internal resistance which is a feature that I want.

Any suggestions would be appreciated.

I started testing my batteries with opus and mine broke within 2 weeks. GearBest sent me a new one for 18$ (shipping) and its going to take a month to get to me.

I've heard other people seem to have no problem with it though.

I actually already owned this one so I dug it out of storage and used it to charge some 18650s. It worked great!
