forget about analyzing Review by MCA

This charger is a joke when it comes to analyzing your batteries.

First, the displayed voltage is 0.3V lower than the voltage measured at battery contacts with a good multimeter. So you will not know how a battery bahaves under chosen load.

Second, after discharging the battery it resets the data and sometimes it restarts the process so if you are not looking exactly before the battery is finished discharging, you will see either 0 mAh capacity or a ridiculously low value like 80mAh for a 2000mAh cell. That is without touching the charger, so operator error or bad contact cannot be the cause.

Conclusion: typical Chinese junk. (Posted on 06-10-21)

No reverse polarity protection Review by Janko

I inserted an 18350 battery wrong way up by accident and the charger smoked and malfunctioned. Otherwise a good charger with a useful testing function. It's just a shame that it has no reverse polarity protection. My cheap and simple Golisi L2 has it. Opus were being a bit cheap here. (Posted on 19-02-20)
