Review on 🔋 AccuPower IQ338: A Powerful Fast Charger and Analyzer Tester for Li-ion, NiMH, and NICd Rechargeable Batteries by Donnie Hickok

Bought 3 years ago and used well, now I'll buy another one. And here's why: I use a lot of rechargeable batteries, especially RCR123a and 18650, and some AAA and AA batteries. As a charger, I'd say it's decent, although not my favorite. It does what it's supposed to do, and you can change the current you charge at (tip: slower is better for battery life, so you're better off with two chargers and extra spares than fewer batteries and a fast charger to keep it going just saying)! ) If you just want a charger and not testing any functions I will say this is not my option for charging. for this I was lucky with Xtar VC4 (Quad Channel, USB powered, suitable for all types of batteries with 4x500mA or 2x1000mA charging in channels 1 and 4), it's enough that I have two of them and with that I continue my table and I'm very happy with it. The real reason I bought the IQ338 and am buying a 2nd one is so I can actually check the capacity of the batteries and for that it works really well (enough for me to take the 2nd). If you're reading this, please understand that most battery manufacturers lie about capacity! . And the only way you really know is if they just don't work (the worst) or if you test them and that's where this charger comes in and does a good job for the price. Patience is required - as a charger this thing has decent speed (like many others), as a tester it's slow, but that's a good thing! Note that this thing does both a CHARGE TEST (discharges the battery from its current state and then charges by measuring both) and a DISCHARGE TEST (fully charged, then fully discharged and then recharged, measuring both the usable discharge capacity and the charge capacity ) can perform. ) and this can be done ON A SINGLE CHANNEL (You can test all four channels at the same time or mix what each channel does. Some chargers only test on ONE channel). The following four charge/discharge rate options are available for you to test: 1. Charge at 300mA, Discharge at 300mA2. Charge at 500mA, discharge at 300mA3. Charge at 700mA, discharge at 500mA4. Charge at 1000mA Discharge at 500mA. Please note that charging faster will SHORTER battery life, and to get an acceptable discharge capacity for your use, you must discharge the battery at the designed rate, which will take some time. . Patience is required here. This is not a minus of this charger, it's just a process. and FYI I usually run charge/discharge tests at 500mA charge rate and 300mA discharge rate as most of my 18650 and RCR123 are used in flashlights, IR illuminators, thermal devices and Arlo cameras. By the way. Part of the patience is why I'm finally buying a second one, or should I say, my IMPATIENCE. This way I can test two batches of batteries at the same time.
