I like the display of the Dlyfull, it looks more modern than from the Opus. But I decided to buy the Opus because of it´s advantages, at least for NiMH. Better selction of low charging currents like 300mA (my favorite for AAA with capacity 750-900mAh) and 700mA (favorite for AA), better selection of discharging currents (200, 300, 500, 700mA) while the T5 only have 500mA. The Opus-display looks more old school but you can see the one kind of parameters of all cells while the T5 shows all parameters of one cell. The only annoying thing on the Opus is the noisy fan.
Batteries are tested in "test mode." Place the battery and press the "mode" button until the word test appears on the right . Then the test will start first by fully charging the battery, then fully discharging it and finally charging it again. The capacity shown is tested while discharging the battery. Hope this helps.
@@reifenabhobeler4331 sorry I have the Dlyfull, 500ma is low enough IMHO but I don't do very many NiMH.... so all good as long as they work well which mine has now for a couple of years. I wish it did LifePo4 but I just bought a power supple for that.. lol's
